Reserves and resources have been evaluated as indicated in Tables 1-1 and 1-2. Mining reserves were calculated at 7,790,271 tonnes at 6.16% zinc and 3.01% lead. Measured and indicated resources are 8,030,000 tonnes at 2.26% zinc and 1.13% lead, while inferred resources total 4,128,000 tonnes at 2.36% zinc and 0.82% lead. Also, an additional 50,332,000 tonnes of non NI 43-101 compliant historical resources contain a combined grade of 4.98% zinc and lead.
*Note: Mineral resources that are not mineral reserves do not have demonstrated economic viability.
Pine Point Property Reserves and Resources
The Pine Point Property was the subject of a recently completed National Instrument 43-101 report (NI 43-101). The reserve and resource technical report was prepared by Pincock, Allen and Holt July 30, 2008 (PAH): the “independent qualified persons” in accordance with the provisions of NI 43-101 were Stuart E. Collins, P.Eng, Don Larsen, Ph. D, P.Eng, and Barton G. Stone CPG. PAH’s work included a thorough review of the geological interpretation, exploration program, and data compilation, including quality assurance/quality control (QA/QC) procedures. All of the parameters used by Tamerlane to define resources and reserves were also reviewed.
Reserves were compiled from historic resources and confirmed during Tamerlane’s 2005 and 2008 core drilling of the R-190 deposit. Reserves were defined by cut-off parameters for the R-190 deposit. Grade shells for 2%, 5% and 7% zinc cutoff grades were constructed. Grade and tonnages for each of the grade shells were calculated using reserve modeling software.
A preliminary NPV analysis was performed on each of the grade shells for the R-190 deposit to determine the optimal grade shell for extraction. The results of the reserve analysis showed that a 3.5% zinc cutoff grade gave the R-190 deposit the highest value resource at 1,005,000 tonnes with grades 10.98% zinc and 5.28% lead.
Five additional deposits in the district contain NI 43-101 compliant 2P reserves calculated at 6.8 million tonnes at a combined grade of 8.11% zinc and lead.
An additional 50,936,000 tonnes of historic resources are located on the property at an average grade of 3.84% zinc and 1.24% lead. A NI 43-101-qualified report has not been completed on the historic resources and they should not be relied on as current mineral resources.
