During the historic Pine Point Mine’s years of operation, Cominco/Pine Point Mines Ltd. drilled off a large number of deposits that were not mined.
Westmin conducted exploration drilling west of the Buffalo River from 1975 to 1981. They identified and located a total of 9 deposits. Three of the deposits have a combined *5,240,000 tonnes grading 11.8% combined zinc plus lead.
No additional exploration occurred following the mine’s closure in 1987.
* Taken from historic records reported by Sinclair and Giroux, 1982. No current NI 43-101 compliant resource calculation has been completed on the deposit nor have they been examined by a qualified person. The resource is not to be relied upon.
Tamerlane conducted drill testing in three of the un-mined mineral deposits between February and September, 2005. Two of the deposits are located in the historic Pine Point Mine area (W85 and G03). The third deposit is located in the area Westmin referred to as the Great Slave Reef property (R190 deposit). Ten holes were targeted within each deposit. Due to climate and drilling difficulties, eighteen holes were completed. Eight holes were completed within the W85 deposit, three within the G03 deposit and seven within the R190 deposit.
Assay results for the sampled holes were within ranges that confirmed the deposits’ historic grades. Thicknesses of intervals with combined zinc and lead grades above 2.0% also confirmed the historic data. Tamerlane’s press releases dated September 22 and September 28, 2005 report the results of the 2005 drill program.
In November 2007, Tamerlane commenced a confirmation drilling program to produce the drill holes necessary for an updated feasibility study that will include NI 43-101 compliant reserves / resources and mine plans for 5 additional deposits in close proximity to R190.
In 2008 Tamerlane began drilling an additional 16 historic deposits. Pine Point's remaining historic resources total 50.9 million tonnes of ore at a grade of 3.84% zinc and 1.24% lead.
In 2010 Tamerlane drilled 24 diamond drill holes at the N204 deposit. The N204 Deposit contains historical resources at 16Mt at a grade of just over 4.0% combined Zn-Pb. N204 is an open pittable deposit and the drilling will be used to potentially upgrade the historical resources into NI 43-101 compliance.

Immediate exploration potential lies in an under-explored 15 kilometer zone at the property boundary between the former Cominco/Pine Point Mines Ltd. and Westmin properties. The property boundary was not thoroughly explored by either company. Longer-term exploration potential also lies to the west of the defined deposits on the Westmin property.
