Matilda Results Deliver Good Gold Grades over Thick Zones
Perth, April 4, 2013 AEST (ABN Newswire) - Blackham Resources Ltd (
ASX:BLK) is pleased to announce first results from recent drilling at the M4 Deposit at the Matilda Gold Project in Western Australia. Blackham is currently drilling a 30,000m RC programme primarily at the Matilda Mining Centre focussing on the M1, M2, M3 and M4 Deposits.
The M4 Deposit has been identified as a priority area to recommence mining operations at the Matilda Mining Centre. The drilling programme was designed to test for extensions of mineralisation beneath the existing resource and to identify high-grade shoots within the broader lodes.
Latest results from this drilling have confirmed the presence of a gently plunging (approximately 30° northwards), high-grade shoot with a strike of approximately 200m that remains open at depth.
Better results include 13m @ 4.51 g/t from 119m in MARC0077 including a high-grade zone of 2m @ 14.0 g/t from 128m and 12m @ 2.48 g/t from 158m in MARC0085. The Company is also encouraged by the re-entry of MARC0062 from an earlier programme. Interpretation of the mineralisation indicated that the initial MARC0062 hole did not completely pass through the mineralised zone.
Extending this hole has converted a bottom of hole intercept of 3m @ 2.65 g/t into 11m @ 3.32 g/t from 134m, substantially increasing the gold endowment in this part of the resource model.
Results support the previous intercepts of 10m @ 5.47 g/t from 120m including 2m @ 12.4 g/t from 121m (MARC0063) and 31m @ 2.32 g/t from 120m (MARC0051) as well as extend mineralisation further beyond the existing resource model.
Several additional zones of mineralisation have also been intersected in the footwall and hanging wall positions which are likely to improve stripping ratios and general mining economics.
This new programme has continued to extend the thick mineralisation outside the existing M4 pit.
Results are generally thicker and higher tenor than intercepted by previous explorers closer to surface, possibly indicating depletion zones in the weathered profile. Further drilling is planned along strike to the north of the M4 pit where previous drilling appears to have been ineffective.
Several holes from the M1 South area have also been received, returning results in line with expectations such as 4m @ 6.04 g/t from 110m in MARC0090. These results will assist in converting Inferred resources to the higher Indicated category.
Blackham's resource inventory at the Matilda Gold Project is currently 25Mt at 1.9g/t for 1.5Moz Au (see Table 1, link below) which includes 14Mt @ 1.8g/t for 784,000oz Au at the Matilda Mining Centre.
A full table of results from this programme can be found in Appendix A. (see link)
Drilling is continuing at the Matilda Project. These are the initial results from the first stage of a large 30,000m programme at the Matilda Gold Project. The Project has numerous targets at the Matilda Mine and the surrounding region and the Company expects to systematically test these targets over the coming months. Drilling will soon turn to the extensions of the M1 and M2 deposits, historically the largest producers at the Matilda Mine.
