The deposit lies in a 40-sq.-km portion of the Dunkwa property, spun off to Ashanti by Montreal-based junior
This latest campaign consisted of 20 shallow reverse-circulation holes, four of which had diamond-drilled tails, for a total of 1,583 metres. The work consisted of both delineation and infill drilling, and provided enough data for an in-house feasibility study.
All 20 holes hit economic-grade mineralization, including highlights such as: 12 metres grading 7.87 grams gold per tonne and another 38 metres of 8.53 grams gold in hole DMP377B; 44 metres from surface grading 10.42 grams gold in hole RMP350A; 90 metres from surface grading 14.58 grams gold in hole RMP365A; and 24 metres of 2.67 grams gold plus another 44 metres of 9.42 grams gold in RMP377A.
Birim says these latest results show the deposit may have more recoverable gold than originally estimated, and that underground development of deeper material may be warranted.
A couple of years ago, an independent study at Mampon delineated a resource of 1.2 million tonnes grading 5 grams gold.
Birim also notes that the majority of Mampon’s contained ounces fall into the oxide category, which generates a higher royalty for Birim than the sulphide material.
When the deposit finally does come into production, ore will initially be mined from an open pit and then trucked 35 km north for processing at Ashanti’s Obuasi complex.
While Birim had once hoped Ashanti would bring Mampon quickly into production, the junior does receive advance royalty payments. Generally, Birim plans to redirect this ongoing royalty flow towards its grassroots exploration elsewhere in Ghana.
Ashanti is also carrrying out a trenching program on the Aboronye gold prospect, situated 400 metres west of the Mampon deposit but still within the Mampon property. Results are expected soon.
