Ngula 1
Initial drilling at Ngula 1 delineated a 150-200m wide zone of multiple east-west striking shears and northwest and northeast crosscutting structures as indicated by artisanal workings and magnetic lineaments. Mineralization has been intersected over a strike length of over 600m and the zone is open in both directions and down dip. Drilling beneath active artisanal workings demonstrated the potential to encounter significant gold mineralization as it intersected robust mineralized shear zones in places hosting wide and high-grade gold structures. Deeper drilling to test the extensions of these structures at depth has commenced, and in-fill drilling to provide data and geological information to determine a resource is planned in 2013. The best results at Ngula 1 (previously reported March 13, June 7 and September 26, 2012) include:
-- TDD0004: 3.13 g/t Au over 25.89m from 41.00m including 9.38g/t Au over 6.30m;-- TDD0005: 8.50g/t Au over 5.14m from 152.85m including 15.59g/t Au over 2.68m, and 93.30g/t Au over 0.38m;-- TDD0054: 8.17g/t Au over 11.05m from 116.95m including 12.90g/t Au over 2.20m and 12.56g/t Au over 4.03m; and-- TRC0013: 17.23g/t Au over 4.00m from 19.00m including 22.53g/t Au over 3.00m and 48.8g/t Au over 1.00m, and 13.00g/t Au over 1.00m from 104m.
Nyakagwe East
Drill results at Nyakagwe East combined with historic drilling demonstrate a mineralized strike length of over 1,000m along at least one structure within zones that contain multiple structures. DD targeted the area under the northern structure of two extensively mined northwest trending zones containing multiple structures, exploited along approximately 750m of strike. RC drilling where no mining has been carried out showed that the northern structure continues and is mineralized over 300m to the northwest and into the next target area, Mgusu. Historical DD and RC drilling showed the target potential with highlights including:
-- DD001: 10.25g/t Au over 3.50m from 38.50m;-- DD005: 9.73g/t Au over 3.40m from 81.94m; and-- RC056: 36.70g/t Au over 1.00m.
To complement historical drilling, the northern zone was targeted with DD to intersect 50m to 100m underneath the workings. Highlights along the Nyakagwe East target northern structure (previously reported July 24, 2012) include:
-- TDD0019: 4.69g/t Au over 1.67m from 67.35m;-- TDD0029: 61.80g/t Au over 0.68m from 277.24; and-- TRC0234: 5.46g/t Au over 2.00m from 109.00m.
The zone is open at depth and along strike in both directions and further drilling is planned to test along the northern zone and the parallel structures. The drill holes also show potential for sub-parallel deeper structures that will be targeted in a future deeper drilling program. Deeper and closer spaced in-fill drilling is also planned in 2013 as Tembo commences resource definition.
Other Targets
Preliminary drilling was conducted at the Mgusu, Nyakagwe Village, Ngula 2, and Iyenze targets. RC drilling at Mgusu (results announced September 5, 2012) intersected significant gold mineralization in an area with numerous artisanal shafts along east-west, northwest and northeast trending magnetic lineaments. At Nyakagwe Village (results announced September 11, 2012), a major artisanal mining area exploited by vertical shafts became a large artisanal open pit extracting high-grade material. Initial drilling intersected two high-grade veins south of the workings and an extremely high-grade zone at depth to the north on an unrelated structure. Follow-up drilling along strike intersected the primary zone to the east and further drilling is planned to test both high-grade prospects. Highlights from the Mgusu and Nyakagwe Village targets include:
