Dear Ralph,
Perhaps this is off the wall, but have you considered checking the unconformity-related uranium literature. Sandstone-hosted uranium deposits in Saskatchewan have abundant Ni-Co-As mineralization, and if memory serves it is relatively low in sulfur. At Key Lake for example the nickel grade is extremely high. What is the uranium content of your Tassie mineralisation?
Cheers

Subject: Co-Ni-As deposits
We have recently found some S-poor Co-Ni-As +/- Au mineralisation in
siliceous breccias in skarns adjacent to serpentine conglomerates. We are
hoping someone can help point us towards recent research on this style of
mineralisation (presumably related to those Ag-rich veins in Germany and
Ontario?).
