Scientific/Process Deep Target Mineral Zonation
Mineralization at the nearby 4100N Zone and elsewhere at Storm is clearly zoned, with a core of chalcocite mineralization grading into zones bornite ± covellite, then chalcopyrite, pyrite and on to an outer sphalerite ± galena zone, reflecting progressive reduction of the metal-bearing fluids by interaction with hydrocarbons in the permeable zones of the rock.
The mineralization encountered in ST22-10 suggests this drill hole intercepted the outer chalcopyrite/pyrite/sphalerite zone of the system. Follow-up detailed EM is expected to improve targeting for the higher-grade chalcocite and bornite zones predicted by the deposit and mineralization models.

Potential for a Significant New Copper System
Initial observations suggest that the style of mineralization, host rocks and the geological setting of the ST22-10 area are evidence of a reduced facies type of sediment hosted copper system. Global examples of these are the giant Kupferschiefer (Germany) and Central African copper deposits.
The geology intersected within ST22-10 has all the elements required for sediment hosted ore forming processes including permeable carbonate rocks, hydrocarbons for reducing fluids, sulphur source and a favourable structural setting. The central graben of the Storm area is an ideal trap for metal bearing fluids and will be a key focus for further exploration.
The mineralization encountered to date shows clear zonation, which will be used to determine vectors to the stronger part of the mineralization system. The presence of zinc and lead in addition to copper suggests that ST22-10 has intersected the margin of a copper dominant sedimentary hosted mineralization system.
