The main zone of mineralization found at Sierra Mojada extends over 6 kilometers in an East-West direction along the base of the Sierra Mojada Range coincident with the Sierra Mojada fault. Over 54 historical mine shafts lie along this strike, mining to depths in-excess of meters.
The area has not been mined with modern mining technology and processes. A summary of the Global resource is shown below. The information set forth above constitutes forward-looking statements. See "Cautionary note regarding forward looking statements".
We also advise U. Securities and Exchange Commission. See "Cautionary note to U. Projects Sierra Mojada: Overview. Mineral resources that are not reserves do not have demonstrated economic viability. Rounding as required by reporting guidelines may result in apparent summation differences between tonnes, grade, and contained metal. Figure 1. The Global Resource represents a combined total of the resource defined in the open pit and underground. The Zinc and Silver Zones : The Global resource encompasses two zones; the zinc zone, and the silver zone and represents an overall average grade for the silver and zinc mineralization across the entire zone of mineralization.
This average grade does not accurately reflect the discreet, high grade zoning of the silver and zinc mineralization that occurs within the resource. To better reflect these high grade silver and zinc zones which form separate coherent bodies within the larger global resource we have broken out the zinc and silver mineralization using zinc and silver cutoff grades and include; A high grade measured and indicated "Zinc Zone" of A high grade measured and indicated "Silver Zone" of 19 million tonnes at an average grade of The Global resource encompasses two high grade zones, the Zinc Zone and the Silver Zone and shown at various cutoff grades in the above image.
Supergene processes have re-mobilized and re-constituted an original sulphide mineralization as oxides into the current 'manto' deposit style we see today hosted in the fault system. It is a coherent zone of mineralization that is 3. Zinc Zone : a well-defined high grade zone of zinc oxide mineralization situated directly below and adjacent to the Shallow Silver Zone. It is a coherent zone of mineralization over 2 kilometers long which remains open to the east and is amenable to both open pit or underground mining.
