HudBay Updates Drilling on Copper-Gold Zone at the Lalor Deposit 17:02 EST Thursday, December 17, 2009 | |
TORONTO, ONTARIO--(Marketwire - Dec. 17, 2009) - HudBay Minerals Inc. ("HudBay", the "company") (TSX:HBM) today announced additional drill results as an update to its September 22, 2009 announcement of the discovery of a Copper-Gold zone at its 100% owned Lalor deposit near its Snow Lake concentrator in the Flin Flon Greenstone Belt.
Notable results intersected in the Copper-Gold zone included DUB263W05, which assayed 9.62 g/t Au, 29.01 g/t Ag, 6.46% Cu, and 0.40% Zn over 30.94 meters from 1261.68 to 1292.62 meters and in drill hole DUB263W03, which assayed 11.75 g/t Au, 35.36 g/t Ag, 5.89% Cu and 0.43% Zn over 32.78 meters from 1253.36 to 1288.14 meters. Please refer to the map entitled "Lalor Cu-Au Zone - Plan View", available on HudBay's web site and at http://media3.marketwire.com/docs/hudbaylalor.pdf for drill hole intersection locations (the "Drill Plan Map").
The Copper-Gold intersection in hole DUB263W05 intersected the 30.94 meters of mineralization approximately 21 meters down plunge to the north from the previously disclosed DUB263W02 (the "Discovery Hole") (13.35 g/t Au, 27.98 g/t Ag, 5.33% Cu and 0.35% Zn over 34.54 meters from 1253.08 to 1287.62 meters). The intended target for this hole was 50 meters down plunge to the north.
The Copper-Gold intersection in hole DUB263W03 was a metallurgical wedge cut located approximately two meters away from the Discovery Hole. In addition to this wedge cut, HudBay has completed six of the nine holes announced in the company's October 8, 2009 news release, including DUB246DPN, DUB249DPN, DUB263W04, DUB263W05, DUB265, and DUB266. Previously completed holes have also had assay results returned, including DUB252, DUB252W02 and DUB263W01.
"We are encouraged by these drill results which demonstrate that the Copper-Gold zone remains open down plunge and we will continue exploration to further define the zone," said W. Warren Holmes, HudBay's executive vice chairman. "A mining contractor has been selected, crews have been mobilized and ramp development is underway with the aims of providing an advanced exploration platform and pre-development opportunities."
The narrow widths and/or low grade results from assays on drill holes DUB252W02, DUB252 and DUB263W01 as shown in Table 1 suggest they define the Copper-Gold zone eastern margin. Drill hole DUB263W04 was intended to test 50 meters down plunge of the Discovery Hole. However, it did not reach its intended target. Assays are pending on this hole and HudBay's management believes it would also limit the extent of the eastern boundary due to the absence of significant visual copper mineralization. Evaluation of gold content is pending assay results.
Hole DUB265 was intended to intersect the Copper-Gold zone at 150 meters down plunge of the Discovery Hole to the north. This hole did not intersect its intended target and drifted to the east. While assays remain pending, no notable visual copper mineralization was observed. However, a Crone borehole electro-magnetic survey taken from DUB265 indicates a strong off-hole conductor approximately 50 to 60 meters to the west, coincident with the original target.
Deflecting the diamond drill hole wedge cuts away from the parent diamond drill hole using directional drilling technology has proven to be successful at Lalor; however at depths greater than 1,000 meters, accurately intersecting proposed targets is more difficult.
The western boundary of the Copper-Gold zone is not as well defined as the east. A narrow zone intersected in DUB249DPN suggests a western limit to the zone. Assay results are pending from DUB246DPN; however no notable copper mineralization was observed. Evaluation of gold content is pending assay results. DUB189, which was previously released on March 3, 2008, may represent a limit of possible extension to the west in the northern portion of the favorable target area as shown on the Drill Plan Map. A Crone borehole electro-magnetic survey is scheduled for this hole to help guide the drilling program.
HudBay currently has two drills operating on the Copper-Gold zone targeting the favorable target area. One drill is targeting the continuity of mineralization between DUB252W01 and the Discovery Hole. The other drill is targeting the down plunge extension of the mineralization 150 meters to the north of the Discovery Hole. Pending the results of this drilling future targets will be assessed. The exploration down plunge to the north and the evaluation of the possibility of other lenses associated with the Copper-Gold zone remain exploration priorities.
