Mithril intersects Stark disseminated and massive sulphides
THE DRILL SERGEANT: Mithril Resources (ASX: MTH) released results of two follow-up diamond drill holes (NRD15001 and 002) recently completed at the company’s Stark copper-nickel-PGE prospect near Meekatharra in Western Australia.
Both holes intersected disseminated and massive copper nickel sulphide mineralisation down dip and along strike from previously drilled mineralisation.
NRD15001 intersected multiple mineralised intervals within a sequence of gabbro and minor intermixed sediments (downhole widths), including:
50.25 metres (from 162.1m downhole) of weak disseminated sulphides (pyrite-pyrrhotite-chalcopyrite);
0.27m (from 213.43m downhole) of massive sulphides (pyrrhotite-chalcopyrite-pentlandite, followed by 10.95m of disseminated sulphides (pyrite-pyrrhotite-chalcopyrite);
7.65m (from 226.75m) of weak disseminated, blebby and stringer sulphides (chalcopyrite-pyrrhotite); and
0.15m (from 246.35m) of massive and stringer sulphides (chalcopyrite-pyrrhotite).
Mithril explained the mineralisation encountered by NRD15001 is approximately 40m down dip of drill hole NRC14008, completed in December 2014, which intersected:
16m @ 0.81% copper, 0.09% nickel, and 0.39g/t PGE’s from 183m, including 4m @1.91% copper, 0.18% nickel, and 0.96g/t PGE’s from 194m.
“NRD15001 intersected a cross–cutting dolerite dyke towards the bottom of the hole which is interpreted to have ‘stoped out’ the prospective basal gabbro contact along which massive sulphides can occur,” Mithril Resources said in its ASX announcement.
“The 0.15 metres of massive and stringer sulphides from 246.35 metres occurs at the lower edge of the dyke and may represent the remains of a thicker massive sulphide unit that was present before the dyke was emplaced.”
The second hole, NRD15002 was drilled as an extension (diamond tail) to reverse circulation drill hole (NRC14002) also carried out in December 2014.
The latest hole intersected 35.25m (from 304.2m downhole) of weak to moderate stringer and disseminated sulphides (chalcopyrite-pyrite).
“The mineralisation extends for at least 22 metres into the footwall sediments below the basal gabbro contact,” Mithril explained.
“The NRD15002 intercepts lie 100 metres north of NRD15001 within the central portion of a largely undrilled 500 metre long modelled EM plate.
“Both holes have been cased for downhole EM surveying and geological logging and sampling is currently underway.
“Drill samples are expected to be dispatched to the laboratory this week for analysis with results expected next month.”
The Stark copper-nickel-PGE prospect is situated within the company’s Nanadie Well project on tenements subject to a Farmin and Joint Venture Agreement with Intermin Resources (ASX: IRC).
Under the terms of the JV, Mithril can earn up to a 75 per cent interest in the project tenements by completing expenditure of $4 million over six years with a minimum expenditure of $250,000 required by 14 April 2015 and before any withdrawal.
