December 2022 Quarterly Activities Report
- Assay results received for initial round of Bekajang Project drilling included exceptional high and bonanza grade gold intercepts within the Bau Limestone, indicating a potentially very significant new deeper zone of endowment, distinct from the traditional shallow Bau Limestone – Pedawan Shale Contact (“LSC”) target.
- The assay results also confirmed consistent high-grade zone of polymetallic mineralisation within the LSC target zone along the northern flank of the historical Bekajang tailings dam.
- Gold assaying of the Jugan Drilling Program was finally completed following receipt of the results for the last two holes, JUDDH-95 & -98. Both encountered higher than average gold grades and further endorse Jugan’s stand-alone potential.
- Environmental Impact Assessment for the proposed Jugan pilot plant and pit was completed and lodged with Natural Resources and Environment Board of Sarawak for decision.
- ZJH Minerals Company Ltd continued flotation test work on Jugan mineral bulk samples in conjunction with design of the on-site pilot processing plant.
The Board of Besra Gold Inc (ASX: BEZ) (“Besra” or “Company”) is pleased to provide this Activities Report for the December Quarter, 2022 which accompanies the counterpart Quarterly Cash Flow Report.
Overview of Bau Gold Project
The Bau Gold Project is located 30km – 40km from Kuching, the capital city of the State of Sarawak, Malaysia, on the island of Borneo (Figure 1) and centred on the township of Bau (Figure 2).
Besra controls, directly and indirectly, a 97.8% interest (92.8% on an equity adjusted basis) of the Bau Gold Project. This project lies at the western end of an arcuate metalliferous belt extending through the island of Borneo. In Kalimantan, the Indonesian jurisdiction portion of Borneo Island, this belt is associated with significant gold mining areas including Kelian (7 Moz) and Mt Muro (3 Moz).
The Bau Gold Project is defined by a gold bearing mineralisation system covering approximately an 8km x 15km corridor. Within this corridor the Company has identified total Resources of 72.6Mt @ 1.4 g/t Au for 3.3Moz, of gold, involving a number of discrete deposits (Table 1), together with a gold Exploration Target ranging between 4.9 Moz and 9.3 Moz, (on a 100% basis). The Bau Gold Project is well serviced by infrastructure including ready access to deep water ports, international airport, grid power, communications, and a multitude of service providers.

Table 1 – JORC 2012 Compliant Resources for the Bau Gold Field Project.
The Bekajang Project lies along a very prospective trend that includes two historical mine sites (Figure 2). The Bukit Young Gold pit (BYG) was mined until September 1992, prior to the redevelopment of Tai Parit that, according to mine records, produced some 440,926 tonnes at a grade of 4.51 g/t Au. Tai Parit recorded production of some 700,000 oz of gold, of which approximately 213,000 oz @ 7 g/t was produced between 1991 and 1997 by Bukit Young Gold Mine Sdn Bhd, the last commercial operator.
Figure 2: Locations of the Jugan & Bekajang projects (highlighted within red boxes) on the Bau Gold Field corridor. Bau township lies adjacent to Bekajang and approximately 30km-40km from Sarawak’s capital, Kuching (refer inset).
Historical drilling provides the basis for a substantial JORC 2012 compliant Resource inventory at Bekajang, comprising:
- A Measured and Indicated Resource totalling 120.4 koz @ 2.0 g/t Au;
- An Inferred Resource of 524 koz @ 1.5 g/t Au; and
- An additional Exploration Target of 0.50 – 0.80 Moz @ 2.0 – 3.0 g/t Au, respectively.
Bekajang Drilling Program
Since August 2022 drilling was suspended until the backlog of drill core assaying was completed, and results integrated into the forward drilling program. Drilling recommenced on 29 December 2022. It involves an initial follow-up program of six fully cored holes positioned to delineate the spatial extent of the interval containing bonanza grade gold intercepted in BKDDH-27. The initial Bekajang drilling program involved a total of 21 fully cored drill holes (BKDDH-12 to -30, inclusive), totalling 1,402m.

Dashed green outline represents interpreted footprint of intrusive body at depth beneath the Bekajang tailings dam, based on DIGHEM anomalies. Detailed illustration of the area contained within the purple rectangle is shown as Figure 4.
During the December Quarter gold assay results were received for BKDDH-12 to -27, inclusive, drilled during the initial Bekajang program up to August 2022 (Figure 4). As shown in Table 2, reproduced from the 22 November 2022 ASX Release, these included some exceptional intercepts.
Table 2 – Summary of significant intercepts from the initial BKDDH drilling program.
Highest gold grade intercepts were encountered along the northern flank of the historical Bekajang tailings dam where previous RC drilling (BKRC067 to 128) identified gold mineralisation near the top of the Bau Limestone and overlying units (predominantly Pedawan Formation shales and mudstones, but also clay dominated lithologies of unspecified age – “Z” lithologies – often intruded or replaced by dacite dykes.
Referred to as the “Limestone-Shale Contact (“LSC”) Target” typically, in this area, it occurs within 5m-30m of the surface and consequently most historical RC drilling terminated at depths of 50m or less. A summary of significant intercepts, summarised in Figure 4, illustrate LSC mineralisation ranges in thickness from 2m (BKDH109) to 29m (BKRC071) with reported gold grades ranging between 2.0 g/t and 5.0 g/t, although locally anomalously higher gold grades had been encountered – such as 12.4m @ 10.4 g/t in DDH102-02 (which includes a silicified interval of 1m @ 132 g/t).
Figure 4: Significant drillhole intercepts and Resource wireframe (in puce) located along the northern flank of the Bekajang tailings dam. Based on geophysical DIGHEM data, the footprint of an interpreted underlying intrusive is shown in green.
Historical assay data also revealed mineralisation along this trend to be characteristically polymetallic, with silver and base metal enrichment. For example, BKRC107 encountered 9m @ 60.0 g/t Ag from 9m depth, within an interval also containing 2.7% Zn and 3.1% Pb. This association of gold mineralisation with base and semi-precious metals at Bekajang is not observed at Jugan.
Besra’s 2022 Bekajang Program was the first comprehensive fully cored program along this trend. As outlined in the ASX Release dated 23 August 2022, visually the cores highlighted pervasive hydrothermal alternation, with a number of the later holes (BKDDH-23, -27, -28, -29 & -30) drilled to depths >100m in order to specifically assess deeper mineralisation potential.
Figure 5: Summary of core lithology and gold assay results for BKDDH-23 showing exceptional gold tenor within the lower Pedawan formation at a depth of 18m-25m.
For some time it had been speculated that there may be a deeper structural component to the mineralisation given that the Resource wireframe, based on historical RC drilling, paralleled a surface mapped NNW-SSE trending fault (Figure 4).
Besra’s 2022 Bekajang Program confirmed mineralisation at the LSC target zone with significant intercepts noted in BKDDH-12, -13, -14A, -16, -18, -23, & -27.
Figure 5 shows the lithological log and correlated assay results for BKDDH-23. This typifies the extent of mineralisation at the LSC level, although in this drill hole exceptional bonanza grades were intercepted.
BKHHD-23 intercepted 8m @ 17.1 g/t, including a bonanza grade intercept of 103 g/t Au within the interval 20.0 to 20.8 m. As shown on Figure 5 the bulk of this high-grade mineralisation lies within a shallow (18m – 21m) shaley unit of the Pedawan Formation, which is bound by two thin intrusives.
Deeper Bau Limestone Mineralisation Potential
BKDDH-27 to -30, were drilled to depths of approximately 100m to evaluate the extent of hydrothermal alteration beyond the typical target depths of LSC RC drilling.
Of the assay results received during the December 2022 Quarter, BKDDH-27confirmed the presence of exceptional gold mineralisation some 40m below, and distinct from, the overlying LSC (Figure 6). Comprising a total interval of 15m this deeper mineralised zone included:
- 2m @ 8.81 g/t Au from 40m to 42m;
- 13m @ 22.91 g/t Au from 58m to 71m including –
- 0.5m @ 209 g/t Au from 60.5m to 61.0m,
- 1.0m @ 64.0 g/t Au from 61.0m to 62.0m,
- 1.0m @31.8 g/t Au from 63.0m to 64.0m, &
- 1.0m @22.3 g/t Au from 64.0m to 65.0m.
The highest gold grades, including an interval with a peak of 209 g/t, are associated with silicified alteration of the host limestone involving vugs, brecciation and veining (Figure 7).
Reflecting these exceptional grades was the occurrence of visible gold which is highly unusual along the Bau Gold Field corridor given that the mineralisation style is predominately Carlin-like, and intimately associated with either pyrite or arsenopyrite.
The grades over the interval 58.4m – 71.0m within BKDDH-27 includes some of the highest documented since modern exploration commenced within the Bau Gold Field corridor.
Karst Related Mineralisation
Although visual inspection of the recovered core from BKDDH-24, -25 & -26, drilled in the southwestern flank of the Bekajang tailings dam, showed weathered clay mineralisation extending down to depths of up to 80m, none of the assay results indicated a gold tenor like that encountered in either the historical Tai Parit or BYG mine sites. Despite the presence of pervasive karstic and other alteration textures, as shown on Table 2, only minor gold mineralisation was identified at depth (BKDDH-25 3.7m @ 0.86 g/t, 4.4m @ 0.82 g/t, 0.9m @ 3.17g/t; BKDDH-26 2.0m @ 0.73 g/t).
Given their proximity to Tai Parit and BYG mines, this implies that the southwestern flank of the Bekajang tailings dam, was exposed to fluid flow and alteration histories sufficiently different from those operative and encompassing the nearby Tai Parit and BYG mines that produced their considerable mineral endowments.
Besra will undertake further analysis to understand the apparent controls of this partitioning and its implications for revising an exploration strategy to identify Tai Parit and BYG analogues within the Bekajang Prospect precinct.

Figure 7: Portion of BKDDH-27 core, between 60.0m-63.7m, illustrating intense alteration in a zone hosting bonanza gold grade: 0.5m @ 209 g/t between 60.5m – 61.0m; 1m @ 64 g/t between 61.0 – 62.0 m; 1m @ 15.9 g/t between 62.0m – 63.0m & 1m @ 31.8 g/t between 63.0m – 64.0m.
The Jugan Project is located approximately 6km NE of Bau township (Figure 2). Contained within the Pedawan Formation, the mineralisation is shallowest across a local topographic high – Jugan Hill.
Previous drilling has formed the basis of the current JORC Resource at Jugan which comprises:
Figure 8: Showing the location of the 2021-2022 Jugan diamond drilling program, highlighting the locations of drill holes JUDDH-95 &-98 in the east of the prospect.
Previous drilling also revealed the bulk of mineralisation to be bound between two thrust faults; the hanging and footwall thrusts, vertically separated by between 40m – 100m. To the northeast of the prospect this thrust-bound sheet rolls over to form a steeply plunging limb, its contained mineralisation remaining open at depth, beyond the current limit of drilling intersecting these thrusts- circa 300m, sub-surface.
Gold mineralisation intercepts for JUDDH-95 & -98 previously released to the ASX on 21 October 2022, are illustrated in Figures 2 to 4 and summarised below as Table 3. These intercepts are estimated based on 0.5 g/t Au cut-off and 1m, or less, of internal dilution.
Table 3 – JUDDH-95 & -98 significant gold intercepts (true thickness).
JUDDH-95 & -98 provided additional subsurface control near the crest of Jugan’s main body of mineralisation’s steeply NE plunging limb, nearly 200m from outcrop. Both holes intercepted superior grades of mineralisation over thick intervals from the surface (Figures 9 & 10). JUDDH-98 confirmed the lateral extension to Jugan’s main body of mineralisation, as previously determined in this area by intercepts in historical holes JNDDH-M02 and MDH05, together with its thickening – mineralisation being intercepted virtually continuously some 70m vertically from the surface at an average gold grade of approximately 1.8 g/t (Figure 9). Of note, at depth in this region, is the interception by several holes of higher gold grade intervals, exceeding 4 g/t. In JUDDH-98 this coincides with an interval of 10m thickness with an average grade of 4.26g/t Au, including 6m @ 7.12 g/t Au, between 65m & 71m. This particular interval can be correlated with similar higher-grade intervals intercepted in MDH-08 and DDH-1337.
Core from this higher-grade interval in JUDDH-98 displays strong carbonate and dickite veining, arsenopyrite and pyrite veining of 5-10%, vein selvedges, stockworks, as well disseminated fine sulphides in bands and breccias of up to 3-5%.
Figure 9: JUDDH-98, showing intercepted mineralisation grades based on nominal, true, 1m sample widths. JUDDH-98 intercepted significant intervals of higher-than-average historical global grades (1.5-1.6 g/t Au) including a maximum of 13.5 g/t Au.
Figure 10: JUDDH-95, showing intercepted mineralisation grades based on nominal, true, 1m sample widths. Virtually continuous mineralisation extends from the surface down to 45m near the interpreted footwall thrust, including an interval with a maximum grade of 6.03 g/t Au.
Flotation Scoping Study
Flotation test work of bulk samples of Jugan mineralisation continued to be undertaken by ZJH Minerals Company Ltd of Zingzen China during the December 2022 Quarter. Initial plans for design of the test-plant are currently being reviewed and finalisation, together with a procurement schedule, is due during the March 2023 Quarter.
Jugan Environmental Impact Assessment
During the December 2022 Quarter, Chemsain Konsultant Sdn Bhd completed community and other stakeholder dialogue meetings prior to finalising the EIA Report. This was submitted to the Natural Resources and Environment Board (“NREB”) Sarawak for its consideration. At the same time an Application for Early Commencement Works (“ECW”) was lodged in order to undertake drilling activities prior to a determination of the EIA. This ECW was approved, by the NREB, on 21 December 2022.
On 31 December 2022, the Company held cash reserves of $3.082m and no debt, which showed the impact of the $1m private placement in October and funds $3.007 received from the underwriter of the Entitlement Offer (see below).
