Hole 98-6, the latest and best result reported by the partners so far, was drilled to test a deep-seated electromagnetic anomaly below and west of hole 98-5A, which intersected 2.6 metres grading 3.62% copper, 2.94% zinc and 159.3 grams silver per tonne at a vertical depth of about 1,080 metres.
The first massive sulphide zone encountered in hole 98-6 graded 3.14% copper, 0.07% zinc and 28.8 grams silver over 8.4 metres (representing a near true-width at a vertical depth of about 1,137 metres), including 0.8 metre of 11.4% copper and 72 grams silver. The sulphide mineralization consists of pyrite, chalcopyrite, pyrrhotite and sphalerite.
The second massive sulphide zone — encountered 24.7 metres farther down hole 98-6 — graded 0.1% copper, 2.04% zinc and 15.8 grams silver over 11.3 metres. Mineralization consists of pyrite, sphalerite and chalcopyrite. In addition, at the end of the zone was a 3.5-metre interval grading 1.20% copper.
Amblin says the first massive sulphide intersection appears to be a new zone, whereas the second may be a continuation of the massive sulphides found in holes 5 and 5A, which were drilled during the summer.
Lastly, 33 metres farther down hole 98-6 is a chalcopyrite-rich stringer zone averaging 2.77% copper and 17.8 grams silver over 2.4 metres. This stringer zone appears to be a continuation of a similar one seen in hole 5A.
Overall, the massive sulphide zones strike east-west and dip about 72 south. Previous drilling and down-hole surveying indicate that the top of the zone drilled in holes 98-2, 5, 5A and 6 is about 800 metres below surface.
Recent down-hole electromagnetic surveying in hole 98-6 indicates the massive sulphide zones have good size and are open at depth and along strike. The surveying also suggests the presence of another sulphide zone, situated between the two massive sulphide zones that were intersected by drilling.
Amblin President Ian Hamilton says that once additional funding is secured, the company will probably drill a series of wedge holes from holes 98-6, 5, 5A and possibly 2 into undrilled areas west of and beneath past drill holes. Another potential target is a gravity anomaly between the past-producing Lyndhurst mine and the areas drilled by Amblin.
The partners are hoping the relatively shallow underground workings of the Lyndhurst mine exploited stringer zones associated with larger, deeper mineralization.
The Lyndhurst property is wholly owned by Globex. Amblin has the option to acquire a half interest by fulfilling obligations that include spending $4 million on exploration by 2001.
