The maiden mineral resource estimation exercise at Mpama South in Democratic Republic of Congo nears completion.
Alphamin Resources reported that the assay results are expected to be announced later this month. To date, the miner has completed 24 235 m of drilling in 89 drillholes at its Democratic Republic of Congo-based Bisie tin complex, which comprises the Mpama South and North operations.
The JSE- and TSX-V-listed tin miner intends to use results from 79 drillholes, totalling 23 109 m of drilling at the complex to update the maiden mineral resource estimation of Mpama South. This will also include an initial 16 drillholes done during 2014/15.
Mpama South is a high-grade tin deposit adjoining the southern end of Alphamin’s operating Mpama North mine. The most significant assay results stem from drillhole BGH079 at the Mpama South prospect and finds tin mineralisation for 15.6 m at a grade of 5% from 290.2 m; including 10 m of mineralisation at a grade of 6.1% tin, from a depth of 291.1 m.
Other significant intercepts from the most recently received batch of drillhole assays, include hole BGH079 with 9 m of tin mineralisation at a grade of 5.63% from 316.9 m; and hole BGH077 that finds 4.8 m of mineralisation at a grade of 4.68% tin from 335.3 m; and 11.4 m of mineralisation grading 2.23% tin from a depth of 318.8 m.
Alphamin notes that the success of the Mpama South drilling is such that the zone of high-grade mineralisation has grown substantially throughout 2021. In addition, the miner reports that visual cassiterite intercepts at Mpama South are now within 85 m of the Mpama North mine and are in the export and assay pipeline already.
