Sovereign Gold Company Limited (ASX:SOC) Obtained Higher Gold Results at Martins Shaft
Sydney, Feb 14, 2012 AEST (ABN Newswire) - Sovereign Gold Company Limited (
ASX:SOC) (Sovereign) has completed twin Diamond and Reverse Circulation (RC) drill holes at Martins Shaft designed to compare the sample integrity of the drill methods.
The results of the diamond twin hole indicate diamond core provides samples that give a more accurate measure of the free gold content and hence higher grades.
The overall gold content of the diamond drill hole was 30.3% higher than the RC hole (3.05 vs 2.34 grams/tonne gold).
- Diamond Drill Hole SGRDD014: 15 metres @ 3.05 grams/tonne gold downhole* including 1 metre @ 15.40 grams/tonne gold.
- Reverse Circulation Drill Hole SGRRC005: 10 metres @ 2.34 grams/tonne gold downhole* including 1 metre @ 12.75 grams per tonne gold.
Further results
Diamond Drill Hole SGRDD014:
- 15 metres @ 3.05 grams/tonne gold from 19-34 metres downhole*
Including:
- 8 metres @ 5.40grams/tonne gold from 21-29 metres downhole*
- 4 metres @ 7.77 grams/tonne gold from 21-25metres downhole*
- 1 metre @ 8.60 grams/tonne gold from 21-22 metres downhole*
- 1 metre @ 15.40 grams/tonne gold from 24-25 metres downhole*
Reverse Circulation Drill Hole SGRRC005:
- 10 metres @ 2.34 grams/tonne gold from 23-33 metres downhole*
Including:
- 1 metre @ 12.75 grams per tonne gold from 25-26 metres downhole*
The exact cause of the variation in gold grades between diamond drill and reverse circulation drill holes is being investigated. The hypothesis is that it is a result of the presence of free gold within the ore body. It appears the reverse circulation chip samples are under reporting gold grades.
However no definite conclusions can be drawn from the current limited data set. Duplicate sampling and sampling of splits from +75 micron and the -75 micron pulp fractions are being undertaken to provide a statistical comparison of gold grades reported for both drilling methods.
* Downhole length, true width not known. All drill intersections are stated as downhole lengths, true width not yet determined.
