TORONTO (miningweekly.com) – Zinc-focused miner Trevali Mining reported that development at its Santander zinc/lead/silver mine, in west-central Peru was in the final phase with initial mining and milling operations scheduled to start early in 2013.

The company said all critical mill and processing infrastructure was now in place and underground development continued to progress, with 1.8 km of ramp completed.

About 100 000 t of ore, averaging 5.6% zinc, 0.65% lead and 1.65 oz/t silver had been stockpiled on the surface for processing when commissioning of the 2 000 t/d plant started.

Trevali said all core site infrastructure was also complete and fully operational, including accommodation units, catering facilities, and various mine planning and site offices.

Construction of the project's 65 km transmission line to the national grid had also been completed and energising the power line was currently being coordinated with the Peruvian regulator in order to reduce disruptions with local end-users.

The company expected the Santander mine to access power from the Peruvian grid before the end of the year. Before this takes place, the site is being powered by the company's run-of-river power station at Tingo and supplemented by a combination of generators and excess power from a neighbouring mining unit.

Underground development has found several zones of potentially significant footwall satellite mineralisation that would require additional drilling and, depending on the results, these could provide additional mill feed.

The company’s Toronto-listed shares closed almost 2% higher at C$1.03 apiece on Tuesday.
