The Dankran project covers an area of 34.65 km2 contiguous to the northeastern corner of Pelangio’s Obuasi project. The Prospecting License covers the same Birimian sedimentary and volcanic stratigraphy that hosts AngloGold Ashanti’s 30+ million ounce Obuasi Mine, 25 kilometers to the southwest, plus several prospective northeasterly striking regional structures. Refer to Figure 1.
An historic gold mine, the Obuom Mine, is located approximately 1.5 kilometers to the northeast of the Dankran project boundary, in an area that is presently designated for formalized Small Scale Mining. The Obuom deposit was discovered during the gold rush in Ghana at the close of World War I and was developed into a small underground operation which ran intermittently during the 1920’s and 1930’s at a peak capacity of 1,000 tons per day, and shut down in 1936 after having reportedly produced 29,000 ounces Au at an average grade of approximately 16 g/t Au. (Gold Deposits of Ghana; Ghana Minerals Commission, 2002). The mining operation focused on two or more 1 to 1.5 meter wide high-grade gold bearing quartz veins occurring along the sheared contact between Birimian metasediments to the northwest and Birimian metavolcanics to the southeast.
Since the 1930’s there appears to have been very limited exploration in the Dankran project area. The Ghana Geological Survey mapped the northern Ashanti Belt in the 1960’s and the BRGM (Bureau de Recherches Géologiques et Minières; the Geological Survey of France) conducted a stream sediment sampling program over the district in the 1980’s. In the early 1990’s Johannesburg Consolidated Investment (JCI) of South Africa conducted soil sampling and geological mapping plus sampling. The details of BRGM and JCI’s work, including precisely where their work was conducted and the results, are not available.
There are no reports of exploration drill testing having been conducted over the Dankran project area in the available literature, making the Dankran project, with 7 kilometers of strike of the world-class Ashanti Belt, one of the last remaining strike-extensive stretches of highly favourable Ashanti Belt geology and structure that has not been significantly explored; certainly not in recent times.
The most recently available Google Earth imagery covering the Dankran-Obuom area from November 2018 shows substantial artisanal mining activity on the government designated Small Scale Mining Area and extending well into the Dankran project area. Artisanal mining appears to have been conducted largely along the drainage networks, but also over areas of higher ground indicating exploitation of insitu material. Refer to Figure 2.
