Vancouver, B.C, August 3, 2022. Sanu Gold Corporation (CSE: SANU) (“Sanu” or the “Company”) is pleased to announce the results of a recently completed auger drill program that outlined 14 km of significant gold bedrock anomalies and commences its initial RC drill program on high priority targets.
- Assay results from first pass auger drilling program outlined 14 km of significant gold bedrock anomalies at Daina, including results of up to 10m at 5.02g/t Au (Table 1)
- Significant gold-in-auger anomalies and significant widths of anomalous gold results (up to 24.5g/t gold) were returned from the auger-drilling program (Table 1).
- The auger results identify a series of parallel structures extending over 10 km at the Daina 1 target composed of sub parallel systems of structurally aligned trends of gold anomalism.
- Auger results confirm that the high-grade gold mineralization previously obtained in rock chip samples at the Daina 2 target have a north and south extension of up to 3 km along strike, and the Daina 6 target with a north and south extension of approximately 1.5km.
- The Auger saprolite anomalies fall within the broader termite mound gold trends, but are significantly more focussed and are coincident with interpreted structures that control the gold mineralization at Daina.
Martin Pawlitschek, President & CEO of Sanu Gold commented: “The intense work our teams have been completing over the last few months is progressively yielding results taking us from the initial steps of defining significant gold geochemical anomalies, gold mineralization in bedrock, to outlining kilometer scale gold bearing structures below the extensive laterite cover and providing attractive targets for our initial RC drill testing program. We look forward to drill results from these exciting targets”.
Details of the Daina Auger Drilling Results
Sanu completed a 10,832m, 1034 holes, Auger drilling program over its Daina gold targets. The Auger drilling program tested a strike length of 10 km of termite mound gold anomalism at Daina 1, 3 km of strike length at Daina 2 and 2km of strike at Daina 6 targets. Drill lines were east west oriented and 400 meters spaced apart. Auger holes were drilled vertical and spaced 25 meters apart. The sampling was done at 2 meters composites with planned hole depth was nominally 10 meters.
The auger-drilling program was undertaken to improve the surface geochemical understanding of the exploration targets within the Daina property using a fast and efficient auger drilling method that would penetrate and sample the saprolite below the widespread lateritic and transported cover. The main objectives were:
- To test the strong termite mound gold anomalies at Daina 1, Daina 2 and Daina 6 targets and define the gold bearing structures within the broad surface geochemical gold anomalies.
- To Test the extensions of the high-grade gold mineralization identified in rock chip samples from local artisanal working pits at Daina 1, Daina 2 and Daina 6 (Figure 1) targets.
- To test below large, laterite-covered areas for gold enrichment
- To generate initial Reverse Circulation (RC) drilling targets.
The auger assay results outlined a total of 14 km of significant gold bedrock anomalies within the Daina 1, Daina 2 and Daina 6 targets (Figure 2) that have the potential to host large volumes of gold mineralisation for further testing with RC drilling.
In addition, the auger results identified a series of parallel structures extending for over 10 km at the Daina 1 target composed of sub parallel, structurally aligned trends of gold anomalism (contour>100ppbAu) in zones of structural dilation (Figure 3). Within this trend is also the gold mineralization defined by the recent rock chip sampling from artisanal mining pits (including 5.16g/t and 1.1g/t Au) and anomalous gold values in auger samples from the saprolite (including 1.46g/t, 1.18g/t, 1.28g/t and 1.22 g/t Au)
The most promising anomalous area is the Daina 2 target, which has a gold in auger anomaly (contour >100ppb) extending over a length of 3km and with consistent widths of 150 to 200 meters (Figure 4). The results generated multiple high-grade auriferous saprolite samples (including 24.5g/t, 6.38g/t and 2.71g/t Au) within a number of auger holes and associated with positive rock chip results obtained from the local artisanal mining pits (including 12.5g/t, 8.78g/t, 7.55g/t and 6.51g/t Au). Rock chip fragments in auger holes along the defined structure consist of oxidized quartz vein fragments in hydrothermally altered whitish, bleached saprolite similar to the rocks mapped from the artisanal mining pits along the trend.
At Daina 6, the auger results show that the gold bearing structure (>100ppb Au) extends for 1.3Km in strike length and has a consistent width of 50m. Local artisan workings along this trend yielded high grade gold from rock chip samples including, 7.41g/t, 6.10g/t, 4.48g/t, 3.18g/t and 3.35g/t Au (Figure 1). Auger results yielded high-grade auriferous saprolite samples include 2,71g/t obtained some 350 meters south of the main working pit (Figure 5).

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 amounting to 5% of the total number of samples shipped to the laboratory was inserted approximately every 20th sample to ensure an effective QAQC program. 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 from the auger drilling program were analyzed using Fire Assay geochemical analysis ‘FAA505′ at the SGS Laboratory in Bamako, Mali. SGS is an independent, internationally recognized and certified commercial laboratory.
An initial RC drilling program has commenced, comprising at least 2,500 metres of drilling. The goal of this program will be to drill-test the high-grade gold results in rock chip samples obtained from artisanal workings and the encouraging results on select lines obtained from the auger-drilling program. The initial RC work program will prioritize Daina 1, 2 and 6 targets (respectively Figures 6 through 11), and then will continue throughout the project area to test the various auger trends along strike, as well as some of the parallel auger trends.
Following these highly encouraging results, the company is planning to drill infill auger holes with a grid pattern of 100m x 20m over parts of the defined mineralized trends to better delineate the identified anomalous areas and to assist in planning for further RC Drilling program over the mineralizing trends.
