Vancouver, B.C., September 9, 2022. Sanu Gold Corporation (CSE: SANU) (“Sanu Gold” or the “Company”) is pleased to announce results of its recently completed infill auger drill program (the “Program”) on the Daina Gold Exploration Permit (“Daina” or the “Permit”) in Guinea, West Africa. As announced by the Company in a news release dated August 25, 2022, an initial reverse circulation (“RC”) drill program is underway at Daina, with results from initial holes pending.
Martin Pawlitschek, President & CEO of Sanu Gold commented:
“The infill auger drill results on key target areas at Dania are highly encouraging and have further delineated the gold bearing trends and extended the strike length of the prospective area to test with RC drilling. These results also demonstrate that high gold grades are present along much of the defined mineralized trends. The initial RC drill program underway at Daina will be optimised to incorporate these latest results.”
The Program returned significant gold in bedrock intercepts above 1 gram of gold per tonne (“g/t Au”) from infill auger drilling at the Daina 1, Daina 2 and Daina 6 Targets and confirm the gold-bearing structures interpreted from the initial regional 400 x 25 m spaced auger drilling program (Figure 1 and Table 1). Program highlights include:
Daina 1 Target
- 8.86 g/t Au over 9 metres (“m”), including 39.30 g/t Au over 1 m (DAI-AUG-1201)
- 6.59 g/t Au over 3 m, including 6.48 g/t Au over 2 m (DAI-AUG-1250)
- 2.26 g/t Au over 9 m, including 9.78 g/t Au over 2 m (DAI-AUG-1246)
Daina 2 Target
- 4.07 g/t gold over 3 m, including 5.83 g/t Au over 2 m (DAI-AUG-1104)
Daina 6 Target
- 1.97 g/t gold over 8 m, including 7.36 g/t Au over 2 m (DAI-AUG-1164)
The Program included 4,000 m of infill drilling in 237 auger drill holes over key target areas on the Permit and tested the extension of gold in bedrock structures interpreted from the initial regional auger drilling program at Daina 1, Daina 2 and Daina 6 Targets. Auger drill lines were east-west oriented, with 100 m line spacing. Auger holes were drilled vertically and spaced at 20 m intervals. Hole depths ranged from 15 to 25 m and 2 m composite samples were collected for the entire length of each hole.
The focus of the program was to follow-up on previously identified gold mineralization at the Daina 1, Daina 2 and Daina 6 Targets. The aim was to better delineate gold-bearing structures for follow-up RC drill campaigns. The results of the Program have provided a refined definition of the lateral extensions of the bedrock gold anomalies previously identified at the target areas.
At the Daina 1 Target, results from the Program delineated two zones of bedrock anomalies, each extending for over 3 kilometres (“km”) along strike and 400 to 600 m in width along a north-northwest orientation (Figure 1). The Program generated multiple high-grade auriferous saprolite samples associated with zones of structural dilation along a north-northwest-trending strike slip fault system (Figure 1 and Table 1). These dilation zones affect hydrothermally altered coarse-grained greywacke with auriferous-sheeted quartz vein sets that are targeted by artisanal miners. The syn-orogenic calc-alkaline granite outcropping south of the Daina 1 Target (Figure 1) along a pronounced east-northeast trend is interpreted to contribute hydrothermal mineralizing fluids and provide the opportunity for the development of zones of structural dilation which focused the flow of such fluids.
At the Daina 2 Target, results from the Program provided better delineation of the gold mineralized structure that extends for over 4 km along the north-northwest structural trend and returned multiple high-grade results (Figure 1 and Table 1). Auger drilling in the Program centered on previous positive rock chip results obtained from artisanal mining pits (including 12.5, 8.78, 7.55 and 6.51 g/t Au, as reported in the Sanu Gold news release dated July 29, 2022). Observations of rock chips in mineralized auger holes and exposed saprolite in artisanal working pits indicate that the gold mineralization is contained in a strongly fractured and hydrothermally altered coarse-grained greywacke that is cross-cut by numerous sheeted quartz vein systems and boxwork after oxidized, disseminated sulphides. Interpretation of the gold-bearing structure from the auger results indicate that the greywacke that hosts the gold mineralization is folded in proximity to zones closely associated with fracturing and brecciation. These fractures and breccia zones provide favorable sites for gold mineralization.
At the Daina 6 Target, folding and fracturing is more apparent (Figure 1). Gold mineralization is associated with a subvertical system of fractures and breccia that affected hydrothermally altered greywacke. These fractures and breccia zones contain quartz veining and boxwork after oxidized sulphides that is targeted by artisanal miners. Two auger drill holes located proximal to artisanal working pits returned high-grade gold mineralization (1.97 g/t Au over 8 m, including 7.36 g/t Au over 2 m; Figure 1 and Table 1). The interpreted gold-bearing structure extends over 1.5 km in strike length and trends north-northwest.
Results from the Program have confirmed the highest priority areas for additional exploration work and provided additional definition of the main gold-bearing mineralized trends at Daina. Follow up RC drilling is currently underway to test the potential depth and strike extensions of the gold mineralization and to obtain an increased understanding of the geology and mineralization in this area. Results from the Program will be incorporated into the geological database for the Permit to optimize and potentially extend the current 2500 to 5000 m RC drill campaign.
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 project 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. 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.
