Thor Mining Successful In Initial Ore Sorting At Spring Hill Gold Project In NT

Thor Mining (ASX:THR) has scored positive results from initial ore sorting test work at its Spring Hill gold project in the Northern Territory, which reiterates the "proof of concept" that the mineralisation can be segregated.

Further test work will be done in South Africa using larger sample size to determine the commercial potential and is likely to take up to 3 months.

Thor has a 51% equity interest in the Spring Hill project, and is exercising rights to increase it to 80% from Western Desert Resources (ASX:WDR). The resource inventory at Spring Hill currently stands at 10 million tonnes at 1.4 grams per tonne (g/t) gold for 450,000 ounces (cutoff grade of 0.5g/t).

The Spring Hill gold mineralisation is vein hosted and the test work was done on near surface oxide ore and the results could be a potential enhancement for the project.

Thor Mining executive chairman, Mick Billing, said, "This is a potentially exciting enhancement for the Spring Hill project. Ore sorting is also commercially used in tungsten processing and a similar scale test on Molyhil material is also in process in South Africa. We eagerly await the outcome of that testwork, as it also has potential to reduce both capital and operating costs for Molyhil."

The ore sorting process is done for certain types of mineralisation, especially to upgrade low grade stockpiles, that allows reduction in downstream processing costs.

After sorting, mineralised material progresses through the rest of the circuit, while non-mineralised material is discarded as waste.
