Highlights
- Metallic screen assay testing of historic samples confirmed the presence of coarse-grained (nuggety) gold mineralization
- Significantly higher grades were seen in samples from Tarabala, including:
- 7 m at 14.13 g/t Au (inc. 1 m @ 97.34 g/t Au), compared to an earlier result of 0.42 g/t Au
- Previous barren interval returned the presence of gold
- 1 m @ 0.92 g/t Au, compared to 0.01 g/t Au
- Preparing to start new drilling program to confirm grade and thickness of mineralized zones at Tarabala and Massala using metallic screen assaying

Background
As previously announced, (see news releases dated
Five 1-m interval samples and one 5-m interval sample were selected from Reverse Circulation (RC) drilling performed at the Tarabala (see news

Table 1 shows the variable nature of gold grades in the retested intervals. Typically, the reproducibility of gold reassays is within 20 percent of the original assays. In this recent program, the reproducibility varies from a 98% decrease to a 6,977% increase, which clearly indicates the nugget effect is present. Of note are the exceptionally high gold grades recorded in diamond drill hole SADD001 from 109 to 116 m: 7 m @ 14.13 g/t Au (metallic screen fire assays) versus 7m @ 0.424 g/t Au (original fire assay), which is highly influenced by one sample that contained 97.34 g/t Au. Similarly, a 1-m interval from RC hole SARC001 at a depth of 85 m, returned a grade of 0.92 g/t Au (SFA) versus 0.013 g/t Au from the original fire assay. Nuggety gold is usually more common at shallow depths (less than 30 m), but this study shows that the largest grade variation is within the fresh rock in samples collected at depths of greater than 80 m.
The significance of the recent metallic screen fire assay analyses is that it is likely that coarse (nuggety) gold has not been satisfactorily analyzed at the prospects along the Tarabala and Moribala faults. This is independently verified by the fact that, while artisanal miners have been recovering coarse gold, Compass’s drilling has detected little or no mineralization (see Compass press releases from
Next Steps
As noted, this next drill program at Tarabala will focus on mineralization at depth within the fresh rock. Ten reverse circulation holes totaling 2,000 m will help ensure as large a sample as possible, while four diamond drill holes for 600 m will reveal the characteristics of the mineralized veins. At least one drill hole will target shallow gold mineralization so metallic screen assaying can be used to quantify the nugget effect at shallow, open-pittable depths. Based on financing, this program is expected to conclude by early February, with results likely available in March.
