Australia-based Elemental Minerals has commenced Phase 3A drilling at the Kola deposit on the Sintoukola potash project located in the Republic of Congo.

The 3A phase of drilling involves two boreholes to test extension of sylvinite seams in the western part of the Kola deposit that exhibited potential high-grade sylvinite at the upper and lower Hangingwall Seam.

Elemental Minerals CEO Iain Macpherson remarked that if any one of these two boreholes reflects positive results, it would boost ELM’s resource target for this ‘super-high-grade’ sylvinite.

"Intersection of a sylvinite Upper and/or Lower Seam would also be a great result, opening up possibility for significant westward extension of these thick high-grade seams upon which the PFS is based," added Macpherson.

The company has worked on 45 boreholes at Kola for target definition and resource estimation, following which focus was switched over to the completion of a prefeasibility study.

"An updated Mineral Resource estimate will be incorporated into the Kola Bankable Feasibility Study which will commence Q2, 2013," the company stated.
