Southern Ore Zone Drilling Update
Sydney, Aug 3, 2015 AEST (ABN Newswire) - KBL Mining Limited (
ASX:KBL) is pleased to announce recent underground drilling at the Southern Ore Zone "SOZ" has secured future production from the B Lode Footwall (Cu-Pb-Zn-Ag-Au) on the 1080 level and outlined further zones of potentially economic mineralisation in the A Lode that will be worked into future mine plans. With process plant expansion and upgrades nearing completion, KBL is well positioned to capitalise on the complete metal suite of the SOZ polymetallic lodes.
Highlights:
- Underground drilling intersects high grade polymetallic (Cu-Pb-Zn-Ag-Au) mineralisation in the B Lode Footwall
- Significant intercepts include:
* 8.75m at 1.1% Cu, 2.1% Pb, 3.9% Zn, 31g/t Ag & 0.4g/t Au (KUSOZ086)
* 5.2m at 1.6% Cu, 1.8% Pb, 4.3% Zn, 28g/t Ag & 0.3g/t Au (KUSOZ087)
* 6.9m at 1.0% Cu, 1.3% Pb, 2.6% Zn, 32g/t Ag &1.6g/t Au (KUSOZ089)
- Continued drilling is planned to target A Lode for the delineation of massive sulphide lenses highlighted by recent intersections including:
* 12.2m at 0.8% Cu, 10.8% Pb, 4.8% Zn, 56g/t Ag & 0.8g/t Au (KUSOZ096)
- Installation of the zinc thickener and flotation cells forecast for completion during the September quarter
Process Plant Upgrades
Process plant expansion and upgrades are advancing with the improved lead circuit successfully increasing lead recoveries during the June quarter. The next phase will see installation of the zinc thickener and flotation cells for continuous sequential production of separate copper, lead and zinc concentrates. These works are being completed in parallel with the CIL construction.
B Lode Footwall Drilling
Fifteen diamond core holes were completed at B Lode Footwall (AB Zone) for a total of 866.6m. The drilling from the 1080RL level was aimed at defining the polymetallic mineralisation identified in December 2014.
The AB Zone mineralisation comprises a corridor up to 14m thick of steeply west-dipping quartz and sulfide matrix breccia. A siliceous alteration halo marks the hanging wall and contains galena-sphalerite spots and stringers throughout. However, the best overall grade is along the eastern footwall contact where chalcopyrite and pyrite form the breccia cement in addition to significant galena and sphalerite. The breccia zone is subject to some local jogs and offsets on flatter west-dipping faults, which have been observed in particular at the footwall contact to the east. Drilling is now complete at AB Zone 1080RL and an ore block is being designed for future stoping. The complete list of significant AB Zone intercepts is presented in Table 1, see link below.
A Lode
During the 1080 level B Lode Footwall drilling, several drill holes were extended to test A Lode to the east, and a further two holes were drilled into A Lode from the 1080RL B Lode Footwall ore drive. The complete list of significant A Lode intercepts is presented in Table 1, see link below.
The drilling to date, in the form of relatively flat drill holes across the A Lode mineralisation supports the interpretation that A Lode comprises a number of 25-40 degrees west dipping massive sulfide lenses which overprint the background quartz-sulfide breccia mineralisation.
Further A Lode drilling is planned from drill sites at the southern end of the 1080 and 1100 level development.
