The Tambang prospect comprised a 10-20m wide structurally controlled veinlet swarm, mapped over 2.2 km of strike length. Recent reverse circulation drilling by Finders has shown erratic correlations with previous diamond drill results, and that potentially ore grade material at Tambang occurs in higher grade shoots of 100 - 200m strike length and each with 0.5 - 2 million tonne potential, within the overall vein system.
With generally high Ag-Au ratios, and also accompanying low grade Zn, Pb and Cu and Mn mineralization, the metallurgy of Tambang is more complex than Jambi but still has potential for significant resources of both gold and silver in high grade shoots. A program of metallurgical test-work to determine the optimum processing options for Tambang ores is currently in progress. Only the central portion of the Tambang vein system has been adequately drill tested within the top 100m, and the system remains largely open at depth.
It is now considered that the Tambang mineralization will require either additional drilling or work on the metallurgy to meet JORC resource guidelines.
The Tambang vein system continues to yield strong encouragement for exploration, as evidenced by recent RC drilling and trench sampling results listed below.
- A new high grade gold-rich shoot that is completely open at depth with an intersection of 7m grading 5.62 g/t Au and 70 g/t Ag from 55m depth within a broader intercept of 24m grading 1.84 g/t Au and 38 g/t Ag and 0.56% Zn from 49m depth in TBGR 29.
- Further high grade shallow silver intersections, including:
- 13m grading 184 g/t Ag and 0.41 g/t Au from 23m in TBGR 21,
- 20m grading 128 g/t Ag and 0.39 g/t Au from 52m depth in TBGR 19
- 1m grading 658 g/t Ag and 0.52 g/t Au from 30m depth in TBGR 20
- Wide low grade gold intercepts, including some narrow but very high grade gold intercepts, from surface trenching, extending over 1 km south from Finders recent drilling, including (horizontal bedrock channel samples in E-W trenches, using 0.3 g/t Au cutoff):
- 40m @ 1.39 g/t Au including 2m at 15 g/t Au in trench TBG 28 (9480250m N)
- 34m @ 3.35 g/t Au including 2m at 50 g/t Au in trench TBG 19 (9479850m N)
- 26m @1.35 g/t Au in trench TBG 7 (9479400m N)
