2018 Drill Program


During 2018, Sibanye-Stillwater completed a 4,923 m diamond drill program (3 holes plus one extension of previous hole) on the Altar project, which was directed and paid for by Aldebaran as part of the earn in agreement (announced by Regulus Resources Inc. on June 29, 2018). Results from that program were never formally released, however details can be found on the Sibanye-Stillwater website. This program was successful in defining long intercepts of higher than current resource grade mineralization and provided follow up targets for future programs. Highlights can be seen below in Table 2.

The grades are uncut. Cu Eq and Au Eq values were calculated using copper, gold and silver. Metal prices utilized for the calculations are Cu = US$3.00/lb, Au = US$1,400/oz, Ag = US$14/oz, and Mo = US$10. All intervals presented above consist of sulphide mineralization. No adjustments were made for recovery as the project is an early stage exploration project and metallurgical data to allow for estimation of recoveries is not yet available. The formulas utilized to calculate equivalent values are CuEq = Cu % + ((Au g/t * 1400) + (Ag g/t * 18) + (Mo ppm * 10 / 14.5833)) / (22.046226 * 3 * 31.1035) and AuEq =Au g/t + ((Cu % * 3 * 22.046226 * 31.1035) + (Mo ppm / 10000 * 10 * 22.046226 * 31.1035) + ((Ag ppm * 18))) / 1400.
