Superior Lake Resources Limited (ASX: SUP) has identified a zinc target at its recently completed exploration programme at the Superior Lake Project in Ontario, Canada.
Executive Director Grant Davey said the results of the 50 element assays and analysis of the whole-rock geochemistry confirm the existence of key geochemical markers associated with VMS systems.
Mr Davey said the Pick North drilling intercepted zinc mineralisation, 0.35m @ 3.5% Zn and 0.25% Cu from 608m within a broader 29m wide zone containing narrow bands of massive and semi-massive pyrrhotite and pyrite.
The Pick North target is approximately 500m north-east of the Pick Lake deposit and encouragingly appears to lie in the same interpreted stratigraphic unit, providing a high priority exploration target.
“VMS deposits are known to occur in clusters and Pick Lake North is a high-priority target area for additional mineralisation,” Mr Davey said.
“The new results from PL19-01 strongly suggest the possibility of mineralisation approximately 500 metres to the north of Pick Lake.
This hole has hit thicker sulphide mineralisation than any of the historical holes drilled to the north of Pick Lake.
“This drill hole, having intersected zinc mineralisation, together with the information from the DHTEM survey and the multi-element geochemistry program sets an interesting drill target to test for another possible mineralised orebody in this region.”
Mr Davey said that having now received the assay results of its recently completed drilling and DHTEM programme exploration, field work for 2019 has now concluded. The key findings of the 2019 exploration programme include:
- The Pick drilling programme, which added 10% to the JORC 2012 resource between the upper and lower lens.
- A review of litho-geochemistry of surface rock chip samples which defined seven targets.
- A Fixed Loop Transient Electromagnetic (“FLTEM”) geophysics survey which defined a number of near mine targets, three of which were selected for drill testing.
- Completion of three diamond drill holes to test the FLTEM Targets defined above.
- DHTEM on the three completed diamond drill holes which confirmed four additional off-hole targets.
- Finally, multi-element geochemical results from the recent drilling have been received confirming that the four targets are within the proximal alteration halo of the VMS system; with zinc mineralisation successfully encountered at Pick Lake in PL19-01 (0.35m @ 3.4% Zn and 0.25% Cu from 608m) within a broader 29m wide zone hosting narrow bands of massive and semi-massive pyrrhotite and pyrite.
