Plymouth Minerals Encounters More High-Grade Spanish Lithium
THE DRILL SERGEANT: Plymouth Minerals (ASX: PLH) released drilling results from a maiden drilling program at the company’s San Jose lithium project in Spain.
Plymouth Minerals has received results for seven of ten holes completed in the current reverse circulation (RC) and Diamond drill program.
The company said the drilling, and drilling by Joint Venture partner Tolsa, has demonstrated the San Jose Lithium deposit is open along strike and at depth with lithium mineralisation extending from surface to in excess of 250 metres vertical and in excess of 500m along strike.
High-grade intercepts include:
142 metres at 1.2 per cent lithium oxide (Li2O) from 67m;
68m at 1.1 per cent Li2O from 91m;
52m at 1.1 per cent Li2O from 18m;
45m at 1.0 per cent Li2O from surface;
34m at 1.3 per cent Li2O from 103m; and
250m at 1.0 per cent Li2O from surface.
“Drilling confirms San Jose is a globally significant lithium deposit with potential to be significantly enlarged,” Plymouth Minerals said in the company’s ASX announcement.
“The deepest hole drilled by Tolsa, hole number SJ-1A, which reached 391.5 metres down-hole and significantly to illustrate the size and scale of the deposit ended with a significant intercept of 6.5 metres at 1.62 per cent Li2O from 386m.
“The deepest diamond hole drilled by Plymouth, MSJ-DD-003 on section 4 reached 250 metres down-hole reported 250 metres at one per cent Li2O and ended in significant grade of 1.08 per cent Li2O.”
Plymouth indicated it is currently reviewing detailed metallurgical testwork reports commissioned by Tolsa for its earlier feasibility study.
Tolsa produced lithium carbonate via a sulphuric acid route and a sulphate roast process with good recoveries.
Plymouth Minerals said it expects to initiate a next stage of the metallurgical testwork program, utilising lessons learned by Tolsa, in the next few weeks to fast track the mineral processing flow-sheet.
