Novo Resources drills 2 m of 15.18 g/t Au at Belltopper

2024-06-03 13:31 ET - News Release

Mr. Mike Spreadborough reports



Recently completed drilling at Belltopper has delivered multiple new significant gold intercepts across a wide range of targets and includes the discovery of two new independent reefs with significant strike potential.

Highlights include:

  • 2 m @ 15.18 g/t Au from 9 m in BTD004.
  • 4.25 m @ 5.88 g/t Au from 274.75 m (inc. 2 m @ 11.15 g/t Au from 277 m) in BTD001.
  • 12.26 m @ 1.45 g/t Au from 185 m (inc. 4.6 m @ 2.64 g/t Au from 185 m) in BTD005.
  • 5.6 m @ 3.14 g/t Au from 219.8 m (inc. 3.04 m @ 4.97 g/t Au from 222.36 m) in BTD001.
  • 7 m @ 1.88 g/t Au from 179 m (inc. 3.19 m @ 3.42 g/t Au from 182.81 m) in BTD006.
  • 19.15 m @ 0.68 g/t Au from 216 m (inc. 1.45 m @ 1.82 g/t Au from 233.7 m) in BTD002.

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).

Significant gold results span a range of mineralisation styles; including oblique to stratigraphy high-grade shear or fault related mineralisation analogous to that at Costerfield or Stawell mines; layer-parallel laminated gold-bearing quartz, quartz breccia, and west-dipping mineralised faults analogous to high-grade Victorian deposits such as at Fosterville mine; and broad, low-grade mineralisation associated with the anticline saddle reef-style that has contributed so significantly to the historical gold endowment of the nearby Bendigo and Castlemaine goldfields.

The recent drilling continues momentum garnered from current exploration efforts and the 2021 - 2022 diamond program which discovered and delineated a gold-bearing felsic porphyry with clear IRG characteristics (confirming a new but hypothesised mineralisation style in the region); in addition to highlighting several underexplored, kilometre-scale, high-grade gold reefs with emerging shoot potential, that have in many cases only been tested by a handful of scout or reconnaissance holes at best.

The diamond drilling program was executed with a strong focus on safety, environment, and community engagement with no incidents. All drill sites used during the program have been rehabilitated.

Previous (2021 - 2022) drilling at Belltopper returned significant results from underexplored historic gold reefs, including: the Missing Link, O'Connor's, Queens Birthday, Panama, and Never Despair reefs; in addition to the more advance-drilled Leven Star Reef, with a current reported inferred resource of 0.82 Mt @ 3.95 g/t Au for 104 koz AU (JORC 2012)1.

Previously reported2 highlight results included:

  • 14 m @ 6.1 g/t Au from 120 m (MD16, Leven Star Reef).
  • 10 m @ 4.9 g/t Au from 173 m (MD16, Leven Star Reef).
  • 8.1 m @ 5.79 g/t Au from 131.9 m (MD21, Leven Star Reef).
  • 6.2 m @ 3.92 g/t Au from 144.6 m (MD21, Leven Star Reef).
  • 7.8 m @ 3.6 g/t Au from 32.2 m (MD13, Leven Star Reef).
  • 3.1 m @ 9.27 g/t Au from 400.9 m (MD20 Queens Birthday Reef).
  • 9.1 m @ 2.4 g/t Au from 65.4 m (MD14 Leven Star / Missing Link intersection)
  • 9 m @ 1.1 g/t Au from 257 m (MD19 O'Connor's Reef)

Drill holes MD17 and MD22 from the 2021 - 2022 program additionally confirmed the sub-surface potential of a gold-bearing porphyritic felsic intrusive discovered and mapped in outcrop with IRG-characteristics ("the Missing Link Granite"). Previously reported3 results testing the gold-bearing felsic porphyry returned:

  • 79.9 m @ 0.26 g/t Au from 197 m (MD17).
  • 45 m @ 0.23 g/t Au from 134 m (MD22).
  • 23 m at 0.46 g/t Au from 18 m (DDHMA3, historic hole infill assayed in 2022).

The 2021 - 2022 drilling demonstrated the potential for high-grade mineralisation on multiple prospective epizonal gold-reefs, in addition to confirming the potential for intrusive hosted or IRG mineralisation at Belltopper. The current program aimed to further test the potential at Belltopper to host occurrences of very-high-grade, world-class, epizonal-style mineralisation.


The six-hole (2,529 m) diamond drilling program (Figure 2) was completed at Belltopper between December 2023 and March 2024 with all results recently returned (including required, additional infill assays). The drill program was designed to test various structural, geochemical, and geophysical (IP) targets across a range of geological settings within the 22 sq km Belltopper tenements.

Table 1 presents all (+2-gram x metre) significant intersections returned from the six-hole program. Refer to Appendices for a full listing of all anomalous (> 0.3 gram x metre) intersections.

Drill hole BTD001 returned significant results on the Leven Star Reef within an emerging high-grade zone, reporting 4.25 m @ 5.88 g/t Au from 274.75 m (includes 2 m @ 11.15 g/t Au from 277 m) (Figure 3); 5.6 m @ 3.14 g/t Au from 219.8 m (Figure 4 ); and 1.94 m @ 2.37 g/t Au from 230 m ( Table 1 ). Drilling extended mineralisation up to 120 m down-dip of previously reported results and confirm a structural repeat (or overlap) of a high-grade segment of the Leven Star Reef in this zone ( Figure 5 ). The Reef remains open at depth.

Table 1: Significant (+ 2-gram x metre) intersections reported for recent drilling at Belltopper (holes BTD001 through BTD006). 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 BTD series Belltopper drilling 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. Calculated as length weighted averages. ^^ Au g/t multiplied by metres.

Figure 5: Drill holes BTD001 and MD16 4 on section with updated geological interpretation. Of note are the lowermost modelled high-grade zones in MD16 and BTD001 which are interpreted to represent fault repetition (i.e. structural thickening) of the Leven Star mineralisation. The Leven Star is lightly drilled at this RL, remains open at depth, and requires further drilling to evaluate mineralisation potential, and the extent of the local structurally overlapping portion of the reef in this developing high grade zone.

Drill hole BTD002 tested one of two high-order IP chargeability anomalies across a key anticline corridor and a potential SE extension of the historic NE-dipping Hanover Reef (Figure 6). A broad zone of mineralisation returning 19.5 m @ 0.68 g/t Au from 216 m in line with the modelled position for the Hanover Reef and nearby position of historic workings strongly suggests this reef was successfully intersected.

Figure 6: BTD002 on section with significant (>5-gram x metre) intersections. The Welcome Fault represents a newly discovered NE-dipping gold reef that is parallel to, and in the hanging-wall of, the targeted Hanover Reef. The anticline is occupied by a significant, gold anomalous quartz saddle reef as intersected by BTD002 (peak intersection of 2.22 m @ 0.43 g/t Au from 467.4 m).

An additional parallel reef "the Welcome Fault," was discovered in the hanging-wall position of the Hanover Reef and returned 4.1 m @ 2.37 g/t Au from 36.1 m (Figure 7). Both the Hanover Reef and Welcome Fault are relatively closely spaced, parallel targets with a potential strike length exceeding 800 m based on historic workings and mapping.

Figure 7: BTD002 from 32.47 m - 39.20 m across the Welcome Fault returning 4.10 m @ 2.37 g/t Au from 36.1 m. This zone is characterised by abundant blebs and veinlets of sulphide (pyrite + arsenopyrite) up to 15% locally. Pervasive sericite alteration with kaolinite gives the altered siltstone and fine sandstone a characteristic bleached appearance.

Up to 15% arsenopyrite and pyrite were logged in the Welcome Fault near surface; and up to 5% in the underlying Hanover Fault indicating a potential source for the IP Chargeability anomaly (Figure 8). This zone is interpreted to trend NW and parallel to both structures and remains mostly untested. BTD002 is the first hole drilled into this high priority, developing NW-trending structural and IP target corridor.

An interpreted saddle reef characterised by a wide intersection of quartz veining was also encountered between 464 - 515 m in BTD002 across an anticline (Figure 6). Anomalous gold averaging >0.1 g/t Au; with a peak intercept of 2.22 m @ 0.43 g/t Au from 467.4 m demonstrate gold fertility and highlight the anticlines as key target features with the potential to host multiple mineralisation styles.

A potential NE extension to the Leven Star and a parallel structure expressed at surface by a historically exploited alluvial gold channel known as Butchers Gully was targeted in BTD003. Two distinct, narrow (< 1 m) sulphide-breccias within wider (> 5 m) zones of intense sericite and clay alteration were encountered at 107.05 m and 132.6 m respectively, with the latter returning a narrow result of 0.3 m @ 3.71 g/t Au from 132.6 m, and the former returning an anomalous result of 0.90 m @ 0.37 g/t Au from 107 m; providing evidence that the Butchers Gully target is mineralised at depth. An intersection of 3.00 m @ 1.00 g/t Au from 318.41 m in BTD003 characterised by increased silica with disseminated chalcopyrite, arsenopyrite and pyrite is interpreted as a potential Leven Star Reef extension.

The second high-order chargeability anomaly was tested on section by holes BTD004 and BTD005 (Figure 8), in addition to several known and interpreted reef positions. Multiple gold occurrences were intersected across both holes (Table 1) with peak result of 2 m @ 15.18 g/t Au from 9 m associated with a thin limonitic tectonic breccia. This new high-grade intercept is flagged for follow up.

Figure 8: Oblique view of IP lines showing chargeability anomalies and key reefs tested as part of current program.

Drill hole BTD005 has intersected the Missing Link Reef, returning 12.26 m @ 1.45 g/t Au from 185 m (includes 4.6 m @ 2.64 g/t Au from 185 m) and extends this prospective reef an additional ~200 m to the north from previous drilling (MD18)5. BTD005 is drilled oblique to the Missing Link Reef and is not considered true width.

Drill hole BTD006 (Figure 9) targets a strong geochemical anomaly immediately adjacent the Taradale Fault. Several mineralised structures were intersected, with the most significant returning 7 m @ 1.88 g/t Au from 179 m (includes 3.19 m @ 3.42 g/t Au from 182.81 m). This intersection likely represents an extension to the Piezzi-Stackyard Reef that was historically mined and explored adjacent the larger O'Connor's reef. The O'Connor's Reef and Piezzi-Stackyard Reef represent a priority target that extends over a 1.8 km strike and is open in all directions. Only three diamond holes drilled to date test these reefs.

BTD006 has also demonstrated that the regionally significant Taradale Fault and associated splays are mineralised, albeit to lower levels, returning a peak result of 1.42 m @ 1.23 g/t Au from 150.43 m along the main Taradale structure.

Figure 9: BTD006 on section testing the regionally significant Taradale Fault and associated splay structures. A significant (>5-gram x metre) intersection along the east-dipping Piezzi Reef Fault returned 7 m @ 1.88 g/t Au and anomalous gold is present across the O'Connors Reef. Both the Piezzi and O'Connor's reefs are interpreted as "Blind Targets," on this section, occurring in the footwall of the Taradale Fault and not daylighting at surface.


Work is currently focussed on reviewing and re-logging historic drill holes relevant to current targets at Belltopper. Several historic holes intersect known or modelled reef occurrences, but in many cases the reefs are either unsampled, partially sampled or niche-sampled only. Where these unsampled prospective reefs are confirmed, they are infill sampled as part of the current program. Assays from infill sampling of historic core are predominantly still outstanding.

Information from the historic core re-logging and infill sampling program forms an important component of a detailed review of the Leven Star mineral resource, which is currently underway.

An expanded spectral logging program on pulps from key historic and recent drill hole samples has also commenced. In conjunction with detailed multi-element data for the corresponding pulps, this will provide another critical layer to be integrated into the targeting model to help vector into the most prospective areas for high-grade mineralisation.

It is anticipated that the remaining data from the current historic core logging and sampling program, in addition to data and interpretation from the hyperspectral sampling program, will be fully integrated into the evolving 3D targeting model at Belltopper by Q3, 2024. At that point, planning for the next phase of drilling and further exploration activities can be executed.

Mapping and surface sampling is additionally planned to follow up significant new reef discoveries in drilling that warrant investigation at surface, in addition to expanding the exercise across priority areas that have yet to be mapped and sampled at Belltopper.


Diamond Core

The diamond drill core was sampled by cutting the core in half longitudinally. Samples were cut to geological boundaries or to a preferred length of 1.0 m. The core was halved along the plane of orientation using a diamond saw and the upper half of the core dispatched for analysis and the lower half returned to the core tray in its original orientation. Sampling interval lengths range from 0.3 m up to 1.3 m. Core loss zones greater than or equal to 0.2 m are recorded. Sampling does not cross core loss zones of greater than or equal to 0.3 m. Depending on their relationship to potential mineralization, zones with core loss less than 0.3 m and greater than 0.1 m can terminate a sampling sequence or be included within a sample interval with the percentage of sample recovery recorded. Where core loss cannot be specifically attributed, the percentage of sample recovery is recorded.

All core samples were crushed and pulverised at ALS Limited in Adelaide, Australia (ALS CRU-21/PUL-23) and sub-sampled for fire assay and multi-element analysis at ALS Limited in Perth, Australia (ALS Au-AA26, ME-MS61).

Drill core duplicates are inserted at a rate of one sample every 25. To produce a duplicate sample, the whole core sample is first cut in half, with half of the core returned to the tray. The other half is then quartered with one quarter used as a primary sample and the other as the duplicate.

Blanks and standards are inserted at a rate of eight samples in 100, with three OREAS CRM standards (OREAS 232, OREAS 239, OREAS 264) and one blanks (OREAS C26d) systematically repeated.

No QAQC issues were detected.
