Bass Metals (ASX: BSM)
ASX Release 17 February 2009
Que River Drilling Update
Bass Metals Ltd (ASX:BSM) is pleased to provide the following update on the Company?s recent drilling at its Que River Mine located in NW Tasmania, as presented to the RIU Explorers Conference today.
Key Points
- PQ Lens yields further high grade intercepts to the north of the current pit limit:
w 18.3 metres at 12.4 % zinc, 6.0% lead, 0.2 % copper, 190 g/t silver and 2.5 g/t gold (QRD1293).
w 5.9 metres at 17.7 % zinc, 9.6% lead, 0.2 % copper, 421 g/t silver and 5.4 g/t gold (QRD1297).
w 1.3 metres at 27.6 % zinc, 10.7 % lead, 0.4 % copper, 443 g/t silver and 5.2 g/t gold (QRD1298).
- These drill results confirm potential Exploration Target of between 40 to 60kt of high-grade PQ style mineralisation.
- Strong gold assays in PQ extensional drilling reflect ?sold PQ ore? grades in January which are 8.3 g/t gold; as well as 19.3 % zinc, 10.5% lead, 0.3% copper and 326 g/t silver.
This report presents the assay results for six Diamond drill holes drilled to test shallow extensions of the high grade PQ Lens north of the existing PQ pit. Assay results received for drill holes QRD1293, QRD1294, QRD1296 to QRD1298 and QRD1300 are presented in Table 1 and schematically in longitudinal section in Figure 1.
The drill holes reported are testing discrete positions along strike of the PQ lens between areas known to have been stoped during the historic underground mining operations in the 1980?s. The Company recently reported an Exploration Target of 40kt to 60kt immediately north and beneath the current Stage 1 PQ pit as shown in Table 2 and Figure 1.

37.00 | 38.00 | 1.00 | 5.9 | 3.0 | 0.1 | 53 | 0.9 |
*Significant intervals reflect interval selection criteria where an intercept generally comprises at least:
? For polymetallic mineralisation ? minimum of 3 metres downhole at a minimum assay cut-off of 5 % (Pb+Zn); or,
? For gold mineralisation - at least 5 metres downhole at a minimum assay cut-off of 1 g/t Au.

Tonnage Range (kt) | Grade Ranges (from ? to) |
Zn (%) | Pb (%) | Cu (%) | Ag g/t | Au g/t |
40 to 60 | 8 to 22 | 4 to 11 | 0.1 to 0.5 | 100 to 350 | 2 to 8 |
This drilling programme resumed this week, and will continue to test the along-strike extensions of the PQ Lens. Detailed information on the Exploration Target and the updated Que River Ore Reserves is provided in Bass Metal?s report to ASX on 10 February, 2009.
Commentary
Drilling results at PQ ?north? provide encouragement for further possible Ore Reserve upgrades as reported recently for Que River. Extensions of the high-gold polymetallic mineralisation within the PQ system appear evident in the reported assays (QRD1297 and 1298). It is worth noting that ore sold in January 2009 (c. 5,250 tonnes) graded approximately 8.3 g/t gold; as well as 19.3 % zinc, 10.5% lead, 0.3% copper and 326 g/t silver. Further production updates are provided in the Company?s presentation to the RIU Explorers Conference, also lodged with ASX today.
I look forward to reporting further on the Company?s progress and outcomes in pursuit of its growth objectives in the near term.
Yours Sincerely
Mike Rosenstreich
