Detailed re-logging and additional sampling from 11 historical diamond holes in priority target areas at the Belltopper Gold Project (‘Belltopper’), has delivered multiple new significant gold intercepts across a range of known and emerging targets.
Significant new intercepts from the recent additional (infill) sampling include:
6.0 m @ 4.37 g/t Au from 169 m (including 5.0 m @ 5.18 g/t Au from 169 m) in DDHMA1 on the Never Despair Reef.
2.0 m @ 7.19 g/t Au from 52 m (including 1.15 m @ 12.01 g/t Au from 52 m) and 2.0 m @ 3.87 g/t Au from 43 m (including 1.0 m @ 6.92 g/t Au from 43 m) in MD04 on the emerging Butchers Gully Fault target, a layer parallel structure to the high-grade Leven Star Reef.
3.1 m @ 3.29 g/t Au from 36 m (including 1.3 m @ 7.26 g/t Au from 37.3 m) in MD06A, also on the Butchers Gully Fault.
2.1 m @ 3.82 g/t Au from 78.9 m (including 0.6 m @ 9.74 g/t Au from 79.3 m) in MD07 on NW Fault 9, an important, west-dipping, sub-parallel trending structure to the high-priority Missing Link Reef target.
13 m @ 0.64 g/t Au from 90 m (including 1 m @ 1.92 g/t Au from 94 m) in DDHMA2 on the West Panama Reef.
These results validate prospective gold intervals identified during the re-logging exercise, including current modelled high-grade gold +/- antimony reefs that were intersected, but not originally sampled in historic programs.
NW Fault 9 and NW Fault 4, identified from previous modelling, belong to an important set of gold-bearing, west-dipping structures that form a component of the anticline-related (e.g. Fosterville-style), epizonal targets at Belltopper.
The re-logging program has confirmed controls on higher-grade mineralisation and refined the position of several target reefs and key structural features such as modelled high-grade shoots and high priority target anticline corridors.
Current focus is on delivering an exploration target for the network of high-grade historic and newly discovered gold reefs at Belltopper and growing the pipeline of conceptual high-value shallow and deeper targets.

Novo Executive Co-Chairman and Acting CEO Mike Spreadborough said, “Belltopper in Victoria is an exciting high-grade gold project, located in a proven gold jurisdiction. The excellent work completed by our geological team, which has uncovered multiple significant intercepts including grades of up to 12.01 g/t Au, highlights the exciting opportunity we have in front of us to further explore and develop Belltopper into a project with size and scale. We have a busy period of work planned at Belltopper at a time when the price of gold is at all-time highs.”
VANCOUVER, British Columbia, Aug. 22, 2024 (GLOBE NEWSWIRE) — Novo Resources Corp. (Novo or the Company) (ASX: NVO) (TSX: NVO) (OTCQX: NSRPF) is pleased to report significant assay results received from a relogging and infill sampling program completed across 11 previously under sampled, historic drill holes, located within priority target corridors at the Belltopper Gold Project (‘Belltopper’) in Victoria (Figure 1).

SUMMARY
A re-logging and infill sampling program completed on 11 previously under-sampled historic diamond drill holes at Belltopper, has delivered multiple new significant gold intercepts across a range of known and emerging targets.
Highlights include:
6.0 m @ 4.37 g/t Au from 169 m (including 5.0 m @ 5.18 g/t Au from 169 m) in DDHMA1.
2.0 m @ 7.19 g/t Au from 52 m (including 1.15 m @ 12.01 g/t Au from 52 m) in MD04.
2.0 m @ 3.87 g/t Au from 43 m (including 1.0 m @ 6.92 g/t Au from 43 m) in MD04.
3.1 m @ 3.29 g/t Au from 36 m (including 1.3 m @ 7.26 g/t Au from 37.3 m) in MD06A.
2.1 m @ 3.82 g/t Au from 78.9 m (including 0.6 m @ 9.74 g/t Au from 79.3 m) in MD07.
13 m @ 0.64 g/t Au from 90 m (including 1 m @ 1.92 g/t Au from 94 m) in DDHMA2.
(Note: See Appendix 2 for complete assay results.)
The mineralisation presented in the body of this news release is not necessarily representative of mineralisation throughout the Belltopper Gold Project. Intercepts are expressed as down-hole intersections and should not be presumed to represent true widths, which vary from hole to hole and between reefs (refer JORC Table 1).

Article content
New intercepts associated with the Never Despair (e.g. DDHMA1) and West Panama (e.g. DDHMA2) reefs (Figure 2), further highlight the unrealised potential for a network of historic high-grade gold-reefs on the Project that have been developed to varying degrees at surface or underground during the mid to late 1800’s, but not extensively mined. Most of the key historic reefs on the project have very little ( 5 holes) to no modern drill testing.
New intercepts reported for the Butchers Gully Fault (e.g. MD04, MD06A) showcase the potential for this emerging +1 km steep, northwest dipping structure, that trends in parallel with the high-grade Leven Star Reef.
The new significant intercept associated with NW Fault 4 (MD07) is notable. This target was mapped as a sub-vertical to steep west-south-west dipping quartz reef and belongs to an important set of gold-bearing, west-dipping structures that form a component of the anticline-related (e.g. Fosterville-style) epizonal targets at Belltopper. The NW Fault 4 target may potentially link with the NW Fault 9 target mapped to the north (Figure 2), which returned 2.0 m @ 15.18 g/t Au from 9 m, in recently drilled BTD0042. These target faults combined have a strike length of ~1 km.

Of further note, both NW Fault 4 and NW Fault 9 are also modelled to interact with the Missing Link Granite, a porphyritic felsic intrusion and hence provide targeted structural intersections to test for intrusion hosted mineralisation, either along the margins of, or extending into, the Missing Link Granite itself.
Detailed information from re-logging allows better understanding of the geology and controls on higher-grade mineralisation at Belltopper. Data from the program has allowed Novo to precisely locate and refine specific target reefs and key structural features, such as modelled high-grade shoots and high-priority target anticline corridors. This is fundamental data that will be applied to ongoing targeting moving forward.

RESULTS AND INTERPRETATION FROM THE RELOGGING PROGRAM
A recent review of archived historic diamond core has highlighted a significant opportunity to validate several targets at Belltopper, by means of re-visiting select historic drill core and completing a re-logging and infill sampling exercise.

Article content
The re-logging program at Belltopper focused on 11 historic drill holes located within current priority target areas (Figure 2). Historic sampling practices vary from hole to hole, but as a general theme, the sampling was restricted to specific targets, or completed as niche-style sampling, and in many instances, what are recognised as gold-prospective zones today, were not originally sampled.
Figure 2, Location of re-logged and infill sampled historic drill-holes with significant new assays highlighted. Callouts represent new assays > 5-gram x meters.
Detailed geology and geotechnical logging were completed on all 11 holes and included collection of magnetic susceptibility and specific gravity data. The re-logging campaign included a sampling component which involved gold and multi-element assaying on previously uncut prospective intervals identified during the re-logging exercise, or across uncut intervals where modelled target reefs are projected to intersect the drill hole. Samples for assay were also collected where previous historic significant assays remained open (either at upper or lower sample intervals), or where infill sampling was extended to cover previous gaps in data between closely spaced historic assays.

Standard QAQC practices were adhered to as outlined in JORC Table 1. In total some 1,643 primary and 225 QC samples were submitted for fire assay gold and multi-element as part of the re-logging exercise. Table 1 highlights all (+2-gram x metre) significant intercepts returned from the recent infill sampling program completed. Refer to Appendices for a full listing of all anomalous (>0.3-gram x metre) intersections. The intercepts presented in both Table 1 and Appendix 2 represent either:
entirely new independent intercepts, or
extension and upgrading of historic intercepts, or
extension and integration of two or more previous intercepts by means of infill sampling.
Table 1, Significant (+ 2-gram x metre) intersections reported for recent infill sampling of historic drill holes at Belltopper. Intercepts calculated with 0.3 g/t Au cut-off and 2 m internal dilution. High grade included intercepts calculated with 1.0 g/t Au and no internal dilution. All significant intersections from recent infill sampling program on historic drill holes reported.

^ All width and intercepts are expressed as metres downhole rather than true width. Most intersections tabulated above will have an oblique component. Refer to drill cross sections and JORC Table 1. Calculated as length weighted averages. ^^ Au g/t multiplied by metres.
The Never Despair Reef was intersected at approximately 170 m down-hole in DDHMA1 and is characterised by a 5m wide zone of silica – sericite altered sediments with intervals of white, bleached puggy fault material and laminated quartz veins (Figure 3). Assays returned 6.0 m @ 4.37 g/t Au from 169 m, including 5.0 m @ 5.18 g/t Au across the reef. Strongly elevated arsenic, and elevated silver, molybdenum and antimony accompany this interval.
Figure 3, DDHM01 from 169.15 m – 174.9 m. Never Despair intersection returning 6.0 m @ 4.37 g/t Au from 169 m. Strongly elevated As, and elevated Ag, Mo, and Sb accompany this interval.
The Never Despair Reef dips to the NE and is currently interpreted up to 675 m along strike. Surface workings are restricted to the central portion of the trend and along a roughly 200 m section of the Never Despair structure, in a complex area where multiple reefs with different orientations converge. Local underground development along the Never Despair Reef itself is primarily within 30 m of the surface below the significant surface workings, although additional development along a 20 m segment of the reef occurs to depths down to 60 m in the south, where the Never Despair Reef converges at depth with the adjacent Panama Fault (Figure 2 and Figure 4).

The Butchers Gully Fault was intersected at shallow depths in several re-logged historic holes, including: MD02, MD03, MD04 and MD06A; with the best intercepts reporting 2.0 m @ 7.19 g/t Au from 52 m (including 1.15 m @ 12.01 g/t Au) and 2.0 m @ 3.87 g/t Au from 43 m (including 1.0 m @ 6.92 g/t Au from 43 m) in MD04; and 3.10 m @ 3.29 g/t Au from 36 m (including 1.3 m @ 7.26 g/t Au) in MD06A. Elevated arsenic, bismuth, and antimony accompany these intervals. This fault typically manifests in shallow core intervals as a limonite-rich zone, with quartz fracture veining and intervals of iron and sulphidic tectonic breccia.
The Butchers Gully Fault is an emerging, +1 km long target reef that dips sub-vertical to steeply to the northwest and trends in parallel with the high-grade Leven Star Reef, which is located roughly 80 m to the southeast (Figure 2 and Figure 4). Refer to Table 1 (>2-gram x metre) and Appendix 2 (>0.3-gram x metre) for additional significant intercepts on these drill holes.
Target NW Fault 4 was intersected at around 80 m down-hole in MD07 (Figure 4) and is represented by a limonite rich puggy tectonic fault breccia host predominantly in silt (Figure 5). A significant gold interval associated with this structure returned 2.1 m @ 3.82 g/t Au from 78.9 m, including 0.6 m @ 9.74 g/t Au. This intercept is bound by a 10 cm section of core loss between 79.9 m – 80.0 m. Elevated arsenic, antimony, bismuth, molybdenum and tungsten accompany this interval.

Figure 4, Geological cross section displaying the portion of drill traces for re-logged holes that fall within the field of view. Refer to Figure 2 for location of cross section A – A’. Cross section is north-facing with a +/- 20 m field of view. Callouts highlight significant intersections > 5-gram x metre that are captured within the field of view. Refer to Appendix 2 for all significant (> 0.3-gram x metre) for drill holes part depicted on section.
Target NW Fault 4 represents a mapped, sub-vertical to steeply west-dipping quartz-bearing tectonic breccia, which is interpreted over an ~ 320 m strike length and modelled to interact with the Missing Link Granite outcrop (Figure 2). Target NW Fault 9 may represent an extension of NW Fault 4, mapped to the north, which returned 2.0 m @ 15.18 g/t Au from 9 m, in previously reported assays for drill hole BTD0043. Both faults report narrow, high-grade results and display similar mineralisation styles and multi-element characteristics. These faults have a combined target strike-length of ~ 1 km (Figure 2 and Figure 4).

Figure 5, MD07 from 76.9 m – 81.0 m. The limonite rich puggy fault breccia represents the NW Fault 4 mineralised structure returning 2.1 m @ 3.82 g/t Au from 78.9 m, including 0.6 m @ 9.74 g/t Au. Elevated arsenic, antimony, bismuth, molybdenum and tungsten accompany this interval.
The West Panama Reef was intersected at around 41 m down-hole in DDHMA1 returning 4.0 m @ 0.64 g/t Au from 41.1 m, and at 90 m down-hole in DDHMA2 returning 13 m @ 0.64 g/t Au from 90 m including 1 m @ 1.92 g/t Au. Elevated arsenic, bismuth, antimony, and tungsten are associated with this interval. Within DDHMA2 this fault is represented by strongly silica and sericite altered and annealed granulestone with well-developed quartz stockwork veining.
The West Panama Reef is a steep to moderately steep, NE-dipping structure that is currently interpreted to extend for ~ 670 m (Figure 2 and Figure 5). Small segments (<10%) of this reef were explored and developed locally down to a depth of around 90 m.

Integration of historic, recent and new exploration data from the current logging and sampling program into an evolving 3D target model is ongoing and fundamental to effective targeting. This includes integration of data and interpretation from the recent hyperspectral sampling program which is currently being progressed and scheduled to be complete by the end of Q3 2024.
The recent re-logging program, coupled with previous exploration, have allowed an improved understanding of the overall prospectivity, mineralisation styles and characteristics, and key structural controls on the higher-grade zones at Belltopper. From these learnings, both the extensions to modelled high-grade zones, along with well understood reefs are targeted; as well as high-value, emerging shallow and deeper conceptual targets, which includes both intrusion related mineralisation, and the world class, Fosterville-style, high-grade epizonal mineralisation, of which Belltopper displays many of these characteristics.

Sampling techniques
Nature and quality of sampling (eg cut channels, random chips, or specific specialised industry standard measurement tools appropriate to the minerals under investigation, such as down hole gamma sondes, or handheld XRF instruments, etc). These examples should not be taken as limiting the broad meaning of sampling.
Include reference to measures taken to ensure sample representivity and the appropriate calibration of any measurement tools or systems used.
Aspects of the determination of mineralisation that are Material to the Public Report.
In cases where ‘industry standard’ work has been done this would be relatively simple (eg ‘reverse circulation drilling was used to obtain 1 m samples from which 3 kg was pulverised to produce a 30 g charge for fire assay’). In other cases more explanation may be required, such as where there is coarse gold that has inherent sampling problems. Unusual commodities or mineralisation types (eg submarine nodules) may warrant disclosure of detailed information.
All drill holes within the Belltopper Project were drilled as either diamond or reverse circulation holes. The detail of the various phases of drilling are discussed under drilling technique in the section below.
Details of sampling and assay methods are discussed in the sections below under the headings sub-sampling techniques and sample preparation and quality of assay data and laboratory tests respectively.

Max Depth
MD12 is the deepest DD hole from the project at 999.8 m. The deepest RC hole was drilled to 118 m. The overall average hole depth from Belltopper is 228 m.
Drill Method
All diamond drilling utilised standard wireline drilling methods.
The MD Series (MD13-MD22) was drilled with triple tube HQ3 and NQ3 core diameter, all other drill phases were drilled with conventional HQ core (63.5 mm diameter) from surface with occasional NQ or NQ2 Core tails.
Core Orientation
All diamond core from the MD Series onwards was orientated to varying degrees. The BTD series utilised a REFLEX ACT III™ digital core orientation system, while DD core from the MD13-MD22 series was orientated with a Boort Longyear TruCore™ orientation tool. Earlier DD core used varying methods of core orientation including a traditional spear method. Bedding and key foliation relationships are well understood and were often used to calibrate the orientation of drill core.

Drill sample recovery
Method of recording and assessing core and chip sample recoveries and results assessed.
Measures taken to maximise sample recovery and ensure representative nature of the samples.
Whether a relationship exists between sample recovery and grade and whether sample bias may have occurred due to preferential loss/gain of fine/coarse material.
Diamond core recovery was recorded in logs run by run and, in general, core loss greater than or equal to 0.2 m was recorded in geological logs. Core loss zones were treated as zero grade in any significant intersection calculation.
Drilling recovery data for RC drilling is recorded in drill logs as good, medium or poor with recovery generally considered by the geologist logging as ‘good’.

The sampling methods utilised are appropriate and representative of the of the drilled ground.
Particularly in historical drilling, occasional core loss was observed within ore zones. More recent drilling efforts focused on ensuring good recovery in these zones.
Significant sample bias or “High grading” due to any core loss has not been observed.

Logging
Whether core and chip samples have been geologically and geotechnically logged to a level of detail to support appropriate Mineral Resource estimation, mining studies and metallurgical studies.
Whether logging is qualitative or quantitative in nature. Core (or costean, channel, etc) photography.
The total length and percentage of the relevant intersections logged.
All diamond drill core was washed and metre-marked, orientated (where appropriate), and then selectively logged for geotechnical parameters (RQD, recovery and rock strength), lithology, mineralisation, weathering, alteration, quartz vein style and percentage and number of quartz veins per metre. Later core logging ( BTD and MD series and relogging of historic core) included measurements for magnetic susceptibility, and representative density measurements. Additional comments relating to specific mineralised intervals were added once assays were received.
Since 2020, many of the historic drilled DD holes have been relogged and infill sampled to ensure consistent interpretation of key features and the identification of any previously missed mineralised zones.
Both wet and dry photographs are available for all MD and BTD series holes and for the vast majority of historic core.
All logging is of a standard that allows identification and interpretation of key geological features to a level appropriate to support a possible mineral resource estimation in the future.
Sub-sampling techniques and sample preparation
If core, whether cut or sawn and whether quarter, half or all core taken.
If non-core, whether riffled, tube sampled, rotary split, etc and whether sampled wet or dry.
For all sample types, the nature, quality and appropriateness of the sample preparation technique.
Quality control procedures adopted for all sub-sampling stages to maximise representivity of samples.
Measures taken to ensure that the sampling is representative of the in situ material collected, including for instance results for field duplicate/second-half sampling.
Whether sample sizes are appropriate to the grain size of the material being sampled.
DD core was sampled by cutting it using a diamond saw longitudinally in half. Samples were cut to geological boundaries or to a preferred length of 1.0 m. Where a core orientation line was present, core was cut 2 cm to the left of the line (when looking down hole). When no cut line was present, core was cut longitudinally down the apex line of the most prominent geological feature (such as bedding or vein boundaries). Once cut, the upper half of core (left side of the tray when looking down hole) is placed in a pre-labelled calico bag and dispatched for analysis. The lower half of core is returned to the core tray in its original orientation.
In general, sample intervals ranged from 0.3 m to 1.3 m.
RC samples (LSRC series) were split using a Jones riffle splitter to a nominal 3-5 kg sample weight.
Field duplicates were representative of the original primary pair either as a quarter core duplicate or RC riffle-split duplicate.
Once at the laboratory, all sample material was crushed and pulverized prior to analysis. Samples from the BTD and MD13-MD22 Series were coarse crushed using the ALS method CRU-21 and pulverise up to 3 kg to 85 % passing 75 microns (ALS Method PUL-23).
The sampling methods and sample sizes are appropriate to the style of mineralisation (fine-grained free gold, fine grained disseminated auriferous sulphides or the oxidized equivalents).

For the recent BTD series, drilling of MD13-MD22, MD12 and any recent infill sampling of historic holes, samples have been submitted to ALS Laboratories Adelaide for analysis using the methods described below:
Gold was analysed with a 50 g ore grade (DL of 0.01 g/t Au) Au fire assay and an atomic absorption spectroscopy (AAS) finish (ALS Method Au-AA26). Original assaying of MD12 used trace level (DL of 0.001 g/t Au) ALS Lab Method Au-AA21 with a nominal 30 g sample weight.
Multielement geochemistry was analysed for a suite of 48 elements obtained by a four-acid near-total digestion with a combination of Inductively coupled plasma (ICP) Mass Spectrometry (MS) and Atomic Emission Spectroscopy (AES) finish on a 0.25 g pulp sample (ALS Lab Method ME-MS61).
Samples from GBM MD01 to MD11 series holes were originally assayed at Amdel Laboratories in Adelaide
Gold was analysed with Fire Assay method FA1 (DL of 0.01 g/t Au)
Multielement geochemistry was analysed with method IC3E using a sample of up to 0.2 g of the analytical pulp digested using a HF/multi acid digest, with solution presented for analysis with ICP Optical Emission Spectroscopy (OES).
Samples from original LSRC, LSRC/D, LSDDH and HMDDH series utilised ALS lab method PM203 for gold analysis (DL of 0.02 g/t Au) based on the aqua regia digestion of a 50 g charge and a fire assay with an Atomic Absorption Spectroscopy (AAS) finish.
The original lab method for DDHMA series holes could not be determined with confidence. Any gold assay of significant grade (0.1 g/t Au) has been resampled using the same lab method as used by the BTD series (Au-AA26 and ME-MS61).
All assays were performed at external laboratories.
A portable XRF available on site during recent drilling has only been used to assist with mineral identification.
QAQC Method
For the recent BTD series drilling, drilling of MD13-MD22 and any recent infill sampling of historic holes (Includes earlier MD, LSDDH DDHMA series holes), staff used an industry accepted QAQC methodology incorporating blind field duplicates, blanks, and certified reference materials (CRM) standards. Standards and blanks were inserted at a rate of four each per hundred samples (see Standard ID table) and field duplicates were inserted at a nominal rate of four per hundred with geologist discretion for duplicate placement.

Laboratory QAQC involves the use of internal lab standards using certified reference material, blanks, splits and replicates as part of the in-house procedures.
QAQC insertion rates for early-stage drilling are in line with industry standards at the time.
The LSRC series included the insertion of field blanks and standards at a rate of approximately 5 per 100 samples and conducted riffle split field duplicates nominally at 20 to 30 m intervals.
Original LSDDH and HMDDH series sampling included the insertion of approximately 12 % field duplicates and the occasional insertion of field blanks and standards.
No QAQC assay data was reported with original DDHMA series samples.
No issues of concern were identified in a comprehensive review of QAQC data associated with the Belltopper project.

Specification of the grid system used.
Quality and adequacy of topographic control.
Drill collar surveys
All BTD and MD series collars were initially surveyed by company staff using a hand-held GPS. At the completion of each program all collars were surveyed in MGA94 Zone 55 and MGA2020 zone 55 by a Registered Licensed Surveyor using a Differential GPS system (DGPS).
Holes drilled by Eureka and the majority of holes drilled by Pittson in the mid 1990’s (LSRC/D & LSRC Series and HMDDH & LSDDH Series respectively) were surveyed in AMG84 Zone 55 by a Registered Licensed Surveyor using a theodolite.
The collar positions for the DDHMA Series are considered less reliable, as they have been digitised off old plan maps. Although the general drill pads for these holes could be located, Novo staff were unable to locate the collar positions.
Most collar positions, except for the DDHMA series collars, have been validated in the field.
A high-resolution LIDAR survey flown in Dec 2022 over the Belltopper project has assisted in validating the collar position of all Belltopper drill holes.
All drill collars have been converted to and are presented in MGA94 Zone 55.
Downhole surveys
Downhole surveying of DD for the MD and BTD series were carried out at a nominal depth of 6 m, then every 25 m from thereon and at end of hole. The BTD series drilling used a REFLEX EZ-TRAC™ digital magnetic hole survey system, while the MD13-MD22 series used a Boart Longyear TruShot™ magnetic multi-shot tool. DD holes MD01-MD11 were surveyed with a magnetic single shot camera
Earlier DD holes were surveyed using a magnetic single shot camera at the collar, then at nominal 50 m intervals down hole and at end of hole depth. RC holes were surveyed at collar and end of hole depth.
Data spacing and distribution
Data spacing for reporting of Exploration Results.
Whether the data spacing and distribution is sufficient to establish the degree of geological and grade continuity appropriate for the Mineral Resource and Ore Reserve estimation procedure(s) and classifications applied.
Whether sample compositing has been applied.
Drilling at the Belltopper project has primarily focused on the Leven Star prospect area. Drilling along this mineralised trend has been at a nominal 30-50 m spacing along strike and down-dip. The deepest Leven Star intersection occurs approximately 400 m below the surface topography.
Drilling outside the Leven Star mineralised trend has been of a scout nature testing narrow lode mineralisation styles.
Coupled with a comprehensive understanding of the historic workings and detailed geological mapping there is good confidence in the continuity of mineralised structures and other geological features outside of the Leven Star mineralised trend.
DD core samples were not physically composited.
RC samples were physically composited into four-meter intervals for initial sampling. Any composited samples returning grade were subsequently resampled at a one-meter infill intervals.
Orientation of data in relation to geological structure
Whether the orientation of sampling achieves unbiased sampling of possible structures and the extent to which this is known, considering the deposit type.
If the relationship between the drilling orientation and the orientation of key mineralised structures is considered to have introduced a sampling bias, this should be assessed and reported if material.
In most cases, holes were drilled across strike at a high angle to the interpreted mineralisation geometry.
No sampling bias is considered to have been introduced by the drilling orientation.
Further discussion regarding drilling orientation is presented under the heading Relationship between mineralisation widths and intercept lengths.
Sample security
The measures taken to ensure sample security.
All samples from the BTD and MD13-MD22 series were transported by a commercial courier directly to ALS Laboratories in Adelaide from the Novo/GBM core facility in Castlemaine, Victoria.
During previous drill programs, samples were either delivered via courier or directly delivered by staff to the appropriate laboratory.
Available core, coarse rejects and pulps are stored at the Novo core facility in Castlemaine, Victoria.

Exploration done by other parties
Acknowledgment and appraisal of exploration by other parties.
The project area has been explored by several companies since the 1970s. In 1987 Molopo/Paringa drilled 3 DD holes for 741.55 m. In 1990-92 Pittson drilled 16 DD holes for 2245.8m. In 1994 Eureka drilled 15 RC holes for 1682.1m and 2 RC holes with DD tails for a further 185.1m.
GBM Resources drilled 12 DD holes (MD01 to MD11 including MD08A) for 3694 m in 2008 followed by a single 999.8 m hole (MD12) which was drilled in March 2010).
In joint venture with GBM Resources, Novo Resources drilled 3161.7 m of HQ and NQ diamond core across 11 holes (MD13 to MD22 including MD18A).
Geology
Deposit type, geological setting and style of mineralisation.
The geology within the project area consists of a series of Early Ordovician turbidites that form part of the Castlemaine Supergroup within the Ballarat-Bendigo Structural Zone of the Lachlan Fold Belt. The sediments comprise of a very uniform and well-bedded sequence of marine sandstone and mudstone interbedded with fossiliferous black shale. The Drummond North goldfield is a north-trending belt of fault-related mineralised zones, extending from the Humboldt reef in the north to the Queen’s Birthday reef in the south, a distance of around 4 kilometres. Approximately 30 % of the tenement area is covered by basalt cover.
Historically two styles of mineralisation have been investigated at Belltopper Hill, located within the Drummond North Goldfield. One comprises steeply dipping, north-west to north-trending quartz veins with associated stockwork zones (e.g. Panama and Missing Link) that were worked to shallow depths in the late 1800s. The other is a northeast-striking zone that cuts obliquely across bedding in the Ordovician sedimentary rocks and was worked for a short time in the 1930s as Andrews Lode but more recently as the Leven Star Zone. Most modern exploration has targeted the Leven Star lode with only modest attention paid to the other reefs on Belltopper or to the reef lines south of the hill where the bulk of historical production occurred.
Recent drilling has also highlighted the potential of saddle reef style mineralisation within the Belltopper corridor.
At Leven Star, the GBM 2008 resource work determined that the reef, up to 8m wide, follows a narrow, brittle fault zone with associated intense fracturing and quartz vein development in the country rock. Deformity and reef width are controlled by lithology with the best development in coarser-grained sandstone units. Sulphide mineralisation occurs as; fine-grained pyrite/stibnite/bismuth-telluride/bismuthinite in quartz veins and country rock fractures, disseminated clots of pyrite-arsenopyrite-stibnite-pyrrhotite-chalcopyrite, and as fine needles and radial clots associated with sericite. Pyrite is most widespread while stibnite-arsenpyrite are restricted to stockwork veins and larger-scale quartz veins. Alteration is dominated by sericite, within quartz veins and as vein selvedge. Carbonate/sulphide alteration is extensive as haloes around breccia zones. Skarn-like assemblages of scheelite/fluorite/cassiterite with coarse bladed calcite and muscovite are also present.
The Drummond/Belltopper mineralisation shares similarities with the Fosterville gold field; mapped distribution and scale of workings, reef geometry, gold in arsenopyrite disseminated in country rocks, sulphide-carbonate alteration and gold antimony association, and mineralisation age (370 Ma).
Mineralisation may be associated with buried intrusion(s) of IRG or porphyry affinity. Evidence for intrusion-related mineralisation includes; outcropping auriferous and altered porphyritic monzogranite with overprinting gold-bearing sheet veins, a Falcon gravity low anomaly spatially associated with the hill and mineralisation, presence of Mo-Bi-W-Te-Sb in soils and rocks on Belltopper, and anomalous Mo-Bi-Sn-W-Cu-Sb-Zn to significant depth in the deep exploration hole MD12.
Drill hole Information
A summary of all information material to the understanding of the exploration results including a tabulation of the following information for all Material drill holes:
easting and northing of the drill hole collar
elevation or RL (Reduced Level – elevation above sea level in metres) of the drill hole collar
dip and azimuth of the hole
down hole length and interception depth
hole length.
If the exclusion of this information is justified on the basis that the information is not Material and this exclusion does not detract from the understanding of the report, the Competent Person should clearly explain why this is the case.
Detailed drill hole information is provided in the accompanying table.
Data aggregation methods
In reporting Exploration Results, weighting averaging techniques, maximum and/or minimum grade truncations (eg cutting of high grades) and cut-off grades are usually Material and should be stated.
Where aggregate intercepts incorporate short lengths of high grade results and longer lengths of low grade results, the procedure used for such aggregation should be stated and some typical examples of such aggregations should be shown in detail.
The assumptions used for any reporting of metal equivalent values should be clearly stated.
Reported gold intersections have been calculated with length-weighted averages using the following parameters: Standard intersections º 0.3 g/t Au cut-off and 2 m internal dilution. º High grade included intercepts calculated with 1.0 g/t Au and no internal dilution. Granite/intrusive intersections º Significant intersections across broad intrusive zones in MD17, MD22 and DDHMA3 were calculated using a 0.1g/t Au cut-off grade and no more than 5m internal dilution.
All width and intercepts are expressed as metres downhole. Calculated as length weighted averages.
Reported core loss was treated as 0 g/t Au grade in all calculations.
The gold assay of a primary sample from a duplicate pair was used in all calculations.
Any isolated gold intersections separated by internal dilution must independently be above the average cut-off grade when including the grades of the internal dilution.
Metal equivalents were not reported.
Relationship between mineralisation widths and intercept lengths
These relationships are particularly important in the reporting of Exploration Results.
If the geometry of the mineralisation with respect to the drill hole angle is known, its nature should be reported.
If it is not known and only the down hole lengths are reported, there should be a clear statement to this effect (eg ‘down hole length, true width not known’).
Reported gold intersections from drilling represent apparent downhole widths.
Most targeted mineralised trends for the Belltopper Project are interpreted to be vertical to sub-vertical with many drill holes intersecting mineralisation at an acute angle of between 30 ° and 65 °. As a result, true widths of most significant intersections are likely to be a reduced factor of reported apparent downhole widths. In general, it is estimated that true width twill be between 40 % and 85 % less than the reported downhole widths.
In summary of more recent drilling:
BTD001 intersects Leven Star at a shallow angle. True widths for these intersections will be between 50 % and 60 % lower than the reported downhole widths.
BTD002 was drilled shallow along the strike of geology with the aim of increasing the potential of intersecting anticline related mineralisation. The two most elevated intersection in BTD002 were Welcome Fault (4.1 m @ 2.4 g/t Au from 36.1 m) and Hanover fault (19.15 m @ 0.7 g/t Au from 216 m in BTD002). BTD002 intersected both structures at a shallow angle and the true width of these structures are likely to be around 40% less than the reported down hole width.
Cross section interpretation of BTD003 indicates that BTD003 intersected Butcher Gully fault at a high angle, while other key intersections from this hole were likely intersected at a shallower angle, and the true width of these structures are likely to be around 20% to 30 % less than the reported down hole width.
Cross section interpretation of BTD004 and BTD005 indicate most drill intersections were at a high angle to intersected reefs with the notable exception of the Missing Link (12.26 m @ 1.4 g/t Au from 185 m) and Missing Link Footwall (3.17 m @ 1.1 g/t Au from 164.11 m) which were both intersected at a shallow angle of around 30 degrees. True widths for these intersections will be approximately 40 % less than the reported downhole widths.
BTD006 intersected Piezzi Reef Fault (7 m @ 1.9 g/t Au from 179 m) at a shallow angle. The true width of this intersection is likely to be between 50 % and 40 % less than the reported downhole width.
Diagrams
Appropriate maps and sections (with scales) and tabulations of intercepts should be included for any significant discovery being reported These should include, but not be limited to a plan view of drill hole collar locations and appropriate sectional views.
Collar plans showing drill collar locations are included.
Balanced reporting
Where comprehensive reporting of all Exploration Results is not practicable, representative reporting of both low and high grades and/or widths should be practiced to avoid misleading reporting of Exploration Results.
A table of significant intersections with a gram metre intersection of greater than 0.3 GM with the detailed parameters is presented within this report.
Other substantive exploration data
Other exploration data, if meaningful and material, should be reported including (but not limited to): geological observations; geophysical survey results; geochemical survey results; bulk samples – size and method of treatment; metallurgical test results; bulk density, groundwater, geotechnical and rock characteristics; potential deleterious or contaminating substances.
Other recent phases of exploration at Belltopper include:
Detailed geological mapping.
