Australia-based uranium-focused company Stonehenge Metals has commenced road construction and plans to begin drilling at its flagship Daejon uranium project in South Korea.

The exploration activities follow the previously announced receipt of approvals including road building, drill site preparation and drilling on land parcel Daejon 6-1.

Stonehenge contracted a drilling operator to undertake the road construction, which began on 28 February 2013.

The company expects construction on the 1.4km long road to complete in 20 to 30 days.

Further, Stonehenge plans to commence diamond drilling to update uranium resource, immediately after conclusion of construction. Drilling will comprise an initial 12 holes for a total of 4,302m of core, the company said.

Samples of mineralised core will be prepared for a chemical assay to test for Uranium, Vanadium and Molybdenum, among others, the results of which are expected to take 4 to 6 weeks.

With the Daejon Environment pre-assessment plan now complete, the company will present the data to the appropriate Korean authorities for evaluation.

This will enable the company to draft an Environmental Impact Assessment and prepare necessary permits that will be included in the pre-feasibility study.
