Vancouver, B.C, Aug 18, 2022. Sanu Gold Corporation (CSE: SANU) (“Sanu” or the “Company”) is pleased to report the results of a recently completed auger drill program that outlined 7 kilometres (“km”) of significant gold in bedrock anomalies associated with high-grade rock chip sample results of up to 89.1 grams of gold per tonne (“g/t Au”) on the Diguifara Gold Exploration Permit (“Diguifara”) in Guinea, West Africa.
Assay results from a first-pass auger drill program have outlined 7 km of significant gold in bedrock anomalies at the geochemically defined DIG 1, DIG 2, DIG 3 and DIG 4 targets within Diguifara.
- Rock chip samples exceeding 1g/t Au include grades of 89.1g/t, 2.96g/t, 2.26g/t, 1.63g/t, 1.56g/t, 1.41g/t, 1.30g/t, 1.07g/t Au (Table 2).
- Assay results from a first-pass auger drilling program outlined four large target areas with a total strike length of 7 km of significant gold bedrock anomalies.
- Significant gold-in-auger anomalies with broad widths of anomalous gold results in the weathered bedrock (assay values up to 4.82 g/t Au) were returned from the auger-drilling program (Table 1).
- The first-pass auger results define four bedrock gold in bedrock targets, each composed of a series of sub-parallel structures associated with coincident gold anomalism (Figure 1).
- Gold trends defined by the auger align with and are located within the broader termite mound anomalies (contour >100 ppb Au), and also follow the interpreted regional structures, and are located in areas that returned high-grade gold in rock chip samples, and are in some places along trend of artisanal mining in saprolite.(Figure 1).
Martin Pawlitschek, CEO of Sanu commented: “With each phase of our systematic exploration programs we continue to confirm and progress towards delineating highly prospective drill targets. The work at Diguifara has progressed to a point where rock chip sampling has confirmed the presence of gold mineralization and kilometer-scale gold trends have been delineated by auger drilling. As soon as the reverse circulation (“RC”) drill program at the Daina Gold Exploration Permit is complete, we will commence initial RC drill testing of our newly defined targets at Diguifara”.
Diguifara Auger Drilling Results
Sanu completed a 11,146 metre (“m”) (1,150 hole) auger drilling program across Diguifara. The auger drilling program targeted the priority gold in termite mound anomalies previously delineated (see Sanu news release dated 9 August, 2022). A fast and cost-effective tool, the power auger allows systematic sampling of saprolite (weathered bedrock) below lateritic and transported cover that reaches thicknesses of 1 to 15 m. Auger drill lines were east-west oriented and spaced 200 m apart; drill holes were spaced at 25 m intervals along each line. A total of 6,317 auger samples (including quality control samples) were sent to the SGS Laboratory in Bamako, Mali (“SGS”) for gold analysis. Results from the auger drilling are highly encouraging and outlined 7 km of significant gold in bedrock anomalies. Bedrock gold trends of this size present highly prospective targets for follow-up RC drill testing.
The most promising target, DIG 1, extends over 3 km along strike, with a consistent width of 200 to 300 m. The DIG 1 target trends north-northwest and hosts multiple high-grade auriferous saprolite samples (including 1.88 g/t Au and 1.09 g/t Au) within several auger holes. The DIG 1 target is parallel to the regional-scale fault zone that defines the thrusted and faulted contact between volcanoclastic sequences and sedimentary domains (Figure 1).
The DIG 2 target extends over 1.5 km in strike length, with withs of 200 to 300 m. This target is composed of a series of sub-parallel trends of gold anomalism in a zone of structural dilation. The DIG 2 target contains anomalous gold values in auger saprolite samples (including 4.82 g/t Au, 2.51 g/t Au and 1.53 g/t Au) and high-grade gold mineralization in rock chip samples from outcrop, including 89.1 g/t Au, 2.96 g/t Au, 2.26 g/t Au, 1.41 g/t Au and 1.07 g/t Au (Figure 1 and Table 1).
The DIG 3 target extends over 1.3 km in strike length, with an average width of 300 meters. The main structure is associated with several secondary parallel structures and extends near the major faulted contact between volcanoclastic sequences and sedimentary domains. Assay results from auriferous saprolite auger samples range up to 0.71 g/t Au and 0.46 g/t Au.
The DIG 4 target is composed of a series of parallel, isolated and discontinuous north-south trending bedrock-mineralized structures extending over a 1 km strike length. High-grade gold mineralization in rock chip sampling from outcrop included 1.63 g/t Au, 1.30 g/t Au and 1.56 g/t Au (Figure 1 and Table 1)
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 amounting to 5% of the total number of samples shipped to the laboratory was inserted approximately every 20th sample to ensure an effective QA/QC 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. The sampling was conducted using 2 m composite intervals. The minimum depth of each auger drill hole was planned to be 10 meters. For drill holes where 4 m of saprolite within the 10 m hole was not intersected, drilling was continued to a greater depth to obtain a minimum of two composite samples of saprolite. All samples from the auger-drilling program were analyzed using fire assay ‘FAA505′ at SGS. SGS is an internationally recognized and commercially certified laboratory and is independent of Sanu.
An initial RC drill program, comprising at least 2,500 m is planned to commence in late August/early September 2022. The goal of this program will be to drill-test the high-grade 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 drill testing program will prioritize the DIG 1, 2 and 3 targets.
