I compared the GS grades against the most significant Iron Cap grades that were reported in the 2016 SEA PFS. Most of the IC holes were 1000 m minimum depth. The IC deposit is closest to GS and described in the SEA corporate presentation as having grades and size that compares favourably with some of the largest and profitable copper/gold mines. I only compared gold grades as there is no significant cu yet at GS. The most siginificant results from the 2013 and 2014 IC drill programs were ranked against the most recent GS results using a gram-meter calculation(grade X intercept length):
Hole |
Grade(g-m) |
IC-14-59 |
841 |
IC-13-49 |
788 |
GS-19-47 |
637 |
GS-19-48 |
608 |
CB-18-39 |
553 |
GS-19-42 |
533 |
IC-14-53 |
350 |
IC-14-58 |
348 |
IC-14-56 |
320 |
GS-19-46 |
303 |
The most recent drilling at GS ranks among the best grades from IC. It is statistically unlikely the best grades have already been encountered at GS with a step out drill program. The next stage at GS is to define the strike length and width with step out and infill drilling , and then a resource estimate.
