Western Australia-based exploration company Solstice Minerals (ASX:SLS) reports it has intercepted a massive sulphide intersection from the ongoing nickel drilling campaign at the GSP Nickel prospect, located within the Ringlock Dam Licence in Western Australia.
The company reports massive nickel sulphides (pyrrhotite and pentlandite) have been logged over the interval of 101.8m to 103.85m in hole GSPDD0005. The massive sulphides are located in the footwall sequence to the ultramafic rocks, and probably represent remobilisation of sulphide from mineralisation originally hosted in the cumulate ultramafic rocks overlying the footwall sequence.
Solstice Minerals Executive Director Alastair Morrison says: “The observation of remobilised massive sulphide at GSP is a significant step in confirming the nickel mineralisation indicated by the historical drill intercepts.

We look forward to the assay results and follow-up DHEM surveys early next year.”
Solstice reports drillhole GSPDD0005 is the fifth hole in a planned 2,030m diamond drilling program designed to confirm the historical drill assay data from the 1960s and 1970s, as well as better define the basal and footwall contact, and provide platforms for downhole electromagnetic (DHEM) geophysical surveys.
It also notes thin massive sulphide veins hosted in the footwall stratigraphy have been logged in the first 4 holes, which confirms the presence of sulphide mineralisation in the footwall across the system.
The Ringlock Dam Licence is located within Solstice’s Kalgoorlie Project, around 65km north of the township of Kalgoorlie. Previous exploration at GSP includes rotary air blast (RAB), reverse circulation (RC) and diamond drilling, plus various surface and airborne geophysical surveys.
Solstice also states the identification of bodies of massive and disseminated nickel sulphides across an ‘extensive’ area in the footwall of the GSP prospect area suggests there is, or has been a ‘significant’ massive nickel sulphide body developed above the remobilised footwall-hosted sulphides.
Downhole EM will be completed on selected holes in the current program, looking for off-hole conductors possibly representative of further massive sulphides not tested in the existing drilling. Further work testing the down-plunge position of the GSP massive sulphide shoot, offset across the Owen Fault is also planned.
Solstice Minerals is Western Australia-focused exploration company with gold and base metal projects in the Eastern Goldfields region. The company listed on the ASX in May this year and is focused on exploring its key projects including the Yarri, Kalgoorlie, Yundamindra and Ponton projects.
