Herencia Resources is starting test work to see if the Dense Media Separation process can be used to treat the ore at its Paguanta zinc-lead-silver-gold project in Northern Chile.

The process enables a large proportion of low density waste to be discarded thereby increasing the metal content per tonne of ore. It also means that lower grade resources could become viable. The test work will commence in July and results should be available in September.

If the DMS process rejects 70% of waste materials then money could be saved on the grinding and flotation circuit. A DMS plant could cost up to $2m but the savings could be much greater.

Following the results, a feasibility study will be carried out on Paguanta, which is 70%-owned by Herencia. If the DMS process does work then capital and operating costs will be reduced.

Herencia recently revealed that there was a further high grade extension to the Cathedral vein at Paguanta. Drilling continues and an updated mineral resource estimate is expected by early September.

At 0.7p a share, Herencia is valued at 6.73m.
