THE BISIE TIN PROJECT SUMMARY
The Bisie Tin Project (100% owned by AFM through its subsidiary MPC sàrl) is a high grade tin deposit located within the Walikale District roughly 180km west-northwest of the regional centre of Goma. Tin was discovered at Bisie in 2004, and has been extensively mined by artisanal miners from two main target areas, Mpama North and Mpama South. Both targets are located along 1.5km of the Mpama ridge which extends over more than 14km, bordering a granitic intrusion. Alphamin led the first formal exploration program at Bisie, starting an exploration drilling campaign in 2012.
Location of the Alphamin Licences
After completing two successful drilling campaigns, with the first programme testing the potential of both prospects, and the second programme aiming to define a Mpama North resource, Alphamin announced an initial inferred resource of 4.01 million tons at 3.5% Sn for 141,200 tons of contained tin on the Mpama North prospect on November 2013. In March 2015, the company announced a resource upgrade with an indicated resource of 2.65 million tons at 4.49% Sn for 119,240 tons of contained tin, and an inferred resource of 1.2 million tons at 3.60% Sn for 42,800 tons of contained tin.
Drilling is still ongoing at Mpama North further down dip and along strike. Drilling has also started at Mpama South in order to generate a first maiden resource.
On the regional exploration front, geochemical soil analysis done with a NITON spectrometer, highlighted an important 6km-long zinc and lead anomaly along the Mpama ridge, two elements closely associated with the Bisie tin mineralisation. Laboratory analysis confirmed the presence of a coincidental 3km tin anomaly along the mid-section of the ridge, extending to 4km south of Mpama South, with the southern extent currently being sampled.
An airborne magnetic and radiometric survey has also been completed over two three of the Alphamin licences. The campaign helped to better define the regional geology and pinpoint new potentially mineralised targets, with a number of these targets existing on the yet to be sampled southern portion of the Mpama ridge. It should be noted that Mpama North and South have similar geophysical signatures to other targets along the Mpama ridge and those tested by geochemical sampling show similar geochemical signatures, boding well for future discoveries.
Future exploration plans include: further defining resources at Mpama North and South, drill testing the best geochemical anomalies on the Mpama ridge and completing the soil geochemistry coverage of PR5266 as well as the examination of the new tin granite targets which have been defined by satellite and geophysical imagery.
