The Fire Tower Zone is situated in the southeastern part of the Mount Pleasant property (see inset map on Geology page). The zone first became active from 1983 to 1985, when it produced 1 million tonnes of ore containing approximately 2,000 tonnes of concentrate grading 70% WO3.
The Fire Tower Zone hosts two primary subzones, known as the West Fire Tower and the North Fire Tower. Both subzones contain significant resources of tungsten and molybdenum, with measurable percentages of bismuth. The zone also hosts the # 7 Tin Lode subzone, an anomalous concentration of indium-bearing tin ore that has yielded assays of up to 300 g/t In.
Resource Estimate. The following table shows the latest estimate of mineral resources in the Fire Tower Zone. These figures are from the Amended Technical Review of the Mount Pleasant Property, including an updated Mineral Resource Estimate on the Fire Tower Zone amended September 24, 2012, prepared by Paul Dunbar of Watts, Griffis and McOuat Limited and Dorota El-Rassi of SPK Consulting, and are compliant with National Instrument 43-101, Standards of Disclosure for Mineral Projects.
Recent Developments. Adex has contracted with several consulting and engineering companies to provide services and studies to complete its prefeasibility study (PFS) and environmental permitting approval for both the North Zone and the Fire Tower Zone. The value of contracts signed to date is approximately CDN$1.7 million of which $1.7 million has been incurred by September 30, 2014. Samuel Engineering Inc. is the lead engineering firm and project manager for the study. Golder Associates Ltd. is completing the mining plan and tailings study while Dillon Consulting Ltd. is conducting water-related environmental and permitting studies applicable to the PFS and working on the EIA project statement. WGM is completing updated resource estimations and Bomenco Inc. is managing the metallurgical testing program in support of the mining plan.
The preparation of the prefeasibility study is proceeding with a target daily mining capacity of 2,900 tonnes per day and a mine life of not less than ten years. It is anticipated that it will be completed in the second quarter of 2015. The Company is also in discussions with several China based smelting companies to process the tungsten, molybdenum, tin and zinc-indium concentrates which might be produced at Mount Pleasant. The purpose of these discussions is to provide payables or contract processing rates for the above metals to the PFS contractors to be inputted into the report.
