Vancouver, B.C., November 1, 2022. Sanu Gold Corporation (CSE: SANU; OTCQB: SNGCF) (“Sanu Gold” or the “Company”) is pleased to announce the results of a recently completed initial auger drilling and artisanal pit sampling program (the “Program”) on the Bantabaye Gold Exploration Permit (“Bantabaye”, or the “Permit”), located 50 kilometres (“km”) south of the multi-million ounce Lefa Gold Mine in Guinea, West Africa. The Program outlined a total of 9 km of gold in bedrock anomalies and returned high-grade gold in pit samples of up to 18.3 grams of gold per tonne (“g/t Au”).
- Broad zones of gold in bedrock anomalies extending over a cumulative 9 km strike length on the Permit have been defined by auger drilling in 6 target areas; these anomalies correlate with previously defined termite mound gold anomalies and artisanal workings,
- High gold grades of up to 18.3 g/t Au were returned from bedrock samples collected from artisanal workings in 2 target areas, and
- The 10 target areas defined on the Permit form a series of sub-parallel gold bearing lineaments that are coincident with interpreted local structures.
Martin Pawlitschek, CEO of Sanu Gold commented: “We are very pleased with the results of our first pass auger drilling and bedrock sampling of artisanal workings at Bantabaye. The results from this program outline a total of nine kilometres of gold in bedrock anomalies coincident with artisanal workings and previously-defined termite mound gold anomalies and will be used to delineate targets for our initial reverse circulation drill program, which we anticipate starting early in the new year.”
The Program included 11,756 meters (“m”) drilled in 658 auger holes over Targets 5 to 10, as well as the collection of bedrock samples from pits in artisanal workings at Targets 2 and 7.
Initial Auger Drilling (Targets 5 to 10)
Auger drilling targeted previously defined high priority gold in termite mound anomalies (see Sanu news release dated September 1, 2022). The objective of this work was to outline shallow bedrock geochemical anomalies, which will be used to delineate initial Reverse Circulation (“RC”) drill targets. A fast and cost-effective tool, the power auger allows systematic sampling of saprolite (weathered bedrock) below a 1 to 15 m thick cover of lateritic and transported cover material.
Auger drill lines were oriented east-west with 200 m line spacing and 25 m drill hole spacing along the lines. A total of 6,151 auger samples were collected and assay results were highly encouraging, outlining a total of 9 km of gold in bedrock anomalies, defined as >0.05 g/t Au from down hole saprolite samples.
Auger drilling outlined a minimum of three north-west to north-northeast oriented trends of gold bearing structures on the Permit. These structures are associated with a complex imbricated system of east-west to west-northwest trending, shallowly south-dipping thrust fault and fold structures that defines the structural contact between sedimentary and volcanoclastic rocks of the Siguiri Basin and intruded by Birimian syn-tectonic felsic and mafic intrusives at Bantabaye North, the northern block of the Permit (Figure 1).
Auger drilling has confirmed the north-northwest-trending gold lineaments associated with a system of north-northwest-trending strike-slip fault systems in Targets 5 and 6, located north of the main thrust fault zone in Bantabaye North (Figure 1). Bedrock gold anomalies extend for over 1 km in Target 5 and 500 m in Target 6. The results of auger drilling have outlined a system of closely spaced sub-parallel sets of structurally aligned bedrock gold anomalies that trend north-northwest. The gold mineralization is associated with volcanoclastic rocks cut by numerous quartz veins and stockwork of white or smoky quartz. This assemblage is the primary target for artisanal mining. Quartz vein float is widespread over the area of Target 5, correlating well with the observations from the auger holes.
Target 8, located southeast of the main thrust fault and fold structures in Bantabaye North, is comprised of a series of parallel northwest trending bedrock gold anomalies, an orientation that lines up with structural measurements observed in the field (Figure 1). The gold anomaly outlined at Target 8 extends over a 2 km strike length and is parallel to the trend of the main thrust fault to the north. The most significant gold-bearing structure identified at this target extends over 1 km in length, with auger sampling in saprolite of up to 0.35 g/t Au over 10 m (hole BAN-AUG-0628).
In Bantabaye South, which covers the southern block of the Permit, auger drilling at Targets 9 and 10 delineated strong north-northeast trending bedrock gold anomalies, each of which extend for over 1.5 km in length (Figure 2). Target 9 has a width of 300 m and Target 10 has a width of 1 km.
Rock Sampling of Artisanal Workings (Targets 2 and 7)
A total of 65 rock samples were collected from pits in the artisanal workings at depths of 5 to 26 m at Targets 2 and 7 (Figure 1).
Multiple rock samples collected from artisanal pits at Target 2 returned high gold grades, including 18.3, 12.9, 10.2, 8.42, 6.82, 4.55, 4.47, 3.93, and 2.89 g/t Au from depths of 6 to 26 m (Figure 1 and Table 1). Gold mineralization in the pits is associated with different styles of alteration, including altered volcanoclastic rocks cut by quartz veins stockworks with evidence of pervasively disseminated, now oxidised sulphides. This target is located within a west-northwest to east-northeast trending fault jog system along the main thrust fault in Bantabaye North. Artisanal pits focused on gold production from mineralized bedrock extend in excess of 200 m along strike and up to 50 m in width. Artisanal gold production at Target 2 began only in recent years and workings currently extend to 30 m depth. Artisanal pits expose rocks within the shallowly southerly dipping thrust fault zone.
Target 7 is located south of the main thrust fault and fold structures in Bantabaye North (Figure 1). Initial auger drilling defined a pronounced north northeast trending bedrock gold anomaly that extends over 2.3 km in length and 200 m in width. Samples from the artisanal workings at Target 7 returned high gold grades, including 5.92, 2.54, 2.49, 1.22 and 1.32 g/t Au at depths of 5 to 10 m (Table 1). This anomaly is associated with a system of parallel fractures that host gold mineralization. Individual fractures can extend up to 700 m along strike. The northern portion of Target 7 has extensive artisanal workings, where free gold is extracted from saprolite of hydrothermally altered and sheared volcanoclastic rock cut by quartz veins, stockwork and breccia.
Following these encouraging results a 3,000 to 5,000 m infill auger drill program, followed by a 2,500 to 5,000 m initial RC drill program, is planned to commence in early January 2023. The goal of these next phases of work will be to drill-test areas that returned high gold grades from artisanal workings and to better define gold-bearing structures delineated from initial auger drilling.
Quality Assurance / Quality Control (“QA/QC”)
Sampling was completed following industry best practices, conducted under the supervision of the Company’s project geologists and the chain of custody from the Permit to the sample preparation facility was continuously monitored. An appropriate number and type of certified reference materials (standards) and blanks totaling 5% of the total number of samples shipped to the laboratory was inserted approximately every 20th sample to ensure an effective QA/QC program was carried out. Data verification of the analytical results included a statistical analysis of the standards and blanks that must pass certain parameters for acceptance to ensure accurate and verifiable results. The auger sampling was done at 2 m composites. The target minimum depth was 15 m. Where the holes did not attain 6 m of saprolite within the 15 m, drilling was continued to attain three composite samples of saprolite. All samples were analyzed using ‘‘Fire Assay FAA505’’ at the SGS Laboratory in Bamako, Mali (“SGS”). SGS is an internationally recognized and commercially certified laboratory and is independent of Sanu Gold.
