A directional drilling program at the Ming massive sulphide deposit in north-central Newfoundland is showing that lower-grade stringer mineralization exists in the footwall of the former producing mine.
Rambler Metals and Mining (RMM-L) released results from six wedge holes over the last month, all of which were drilled by Rambler’s 30% owner, Altius Minerals (ALS-V, ATUSF-O). All have intersected multiple zones of copper mineralization.
The target is the gently northeast-dipping footwall beneath the Ming massive sulphide deposit, which contained 2 million tonnes grading 3.5% copper and 2.4 grams gold per tonne. Drilling in 2004 and 2005 intersected copper values mainly in the 1% to 3% range over significant widths.
Drill holes off mother-hole RM06-04 intersected from three to five mineralized horizons, interfingered with either volcanic rocks with low-grade copper mineralization or later intrusive rocks. Typical of the results were four intersections in hole RM06-04D, which ran 1.74% copper over 3 metres, 3.2% copper over 10.5 metres, 1.94% copper over 6 metres and 2.13% copper over 4.5 metres. Those intersections were in the footwall zone, at hole depths between 1,069 and 1,151 metres; the hole also intersected 5 metres in the massive-sulphide horizon that graded 2.17% copper and 2.7 grams gold.
Among the higher-grade intersections in the footwall zone were intervals of 15 metres grading 2.53% copper and 13.5 metres grading 2.49% copper in hole RM06-04B, and 17.4 metres grading 3.18% copper in hole RM06-04E.
The five holes drilled off hole RM06-04 pierced the footwall zone over an area about 100 by 100 metres. A sixth hole, RM-06-03B, tested the same horizon about 200 metres to the southwest (updip), intersecting 3.32% copper over 6.4 metres and 2.42% copper over 11 metres.
