    Superior Lake’s Pick North drilling intercepts Zinc mineralisation

    Superior Lake Resources Limited (ASX: SUP) has announced an encouraging update following the completion of its exploration program at the Superior Lake Project in Ontario, Canada.

    The company reported that assay results from recently completed drilling north of Pick Lake confirm the intersection of zinc sulphides – hole 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.

    SUP said that this broad sulphide zone with zinc mineralisation is a priority exploration target. The company said that it is located along the same stratigraphic horizon that hosts the Pick Lake deposit.

    The company reported that the DHTEM indicates a conductive plate associated with the new sulphide intercepts. SUP reported that the assays and geochemical analysis confirm the existence of typical VMS systems markers being iron, zinc, and copper bearing sulphide minerals.

    Superior Lake project

    The Superior Lake Zinc Project is located approximately 200km’s east of Thunder Bay in the province of Ontario, Canada. The Project covers 175km2 and consists of two deposits – Winston Lake and Pick Lake.

    Superior Lake exploration

    The company had recently completed drilling and DHTEM program exploration at Superior Lake. The assays results have now been received, concluding the field work for 2019.

    The key findings of the 2019 exploration program include The Pick drilling program, 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; and DHTEM on the three completed diamond drill holes which confirmed four additional off-hole targets

    Zinc mineralisation encountered

    The company reported that the 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.

    SUP said that zinc mineralisation was 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.

    Pick North target

    The company said that mineralisation encountered in hole PL19-01 is located along the same stratigraphic horizon that hosts the Pick Lake deposit.

    SUP said that this broad sulphide zone with zinc mineralization is open for at least 1.5km along the mineralised trend and is in a corridor of ~1.5km x 1.8km deep that has been sparsely tested by drilling. SUP reported that only four drill holes have been drilled in this region with three having hit sulphide mineralization.

    Applicability of DHTEM and FLTEM

    The Company said that it believes that the exploration program completed in 2019 has been an important success in that it has successfully demonstrated the applicability of both surface FLTEM and subsurface DHTEM in locating massive sulphides positions and that the use of multi-element geochemistry can discriminate the stratigraphic units and alteration present within the ore system.

    SUP noted that the first three drill holes targeted using the combination of these techniques have successfully hit sulphide mineralisation and demonstrated that a combination of exploration techniques can be used to vector towards mineralisation within the large volumes of rock that remain untested in the near-mine environment.

    SUP reported that 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. The typical VMS systems markers being iron, zinc, and copper bearing sulphide minerals.

    Next steps

    The company reported that further work planned for the Superior Lake Project includes assays and analysis; completion of the geophysics modelling of the DHTEM program; and completion of Optimisation study review of the BFS.

    Management comments

    SUP’s Executive Director Grant Davey commented: “VMS deposits are known to occur in clusters and Pick Lake North is a high-priority target area for additional mineralisation.

    The new results from PL19-01 strongly suggest the possibility of mineralization 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.
