    Block 3/Gold exploration in Presidio Co.

    While Aurcana is opportunisticly picking some low hanging fruit so to speak ( open pit mines ) it gives them more time to explore the rest of the property to cherry pick the best sources of mineral ores.

    La Negra is a perfect example or a mine and mill that can blend different materials to produce a number of metals at the same time. La Negra's lead and zinc production doubles up the silver revenue. If Shafter can get to that point then silver revenues could be doubled up with Gold, lead and zinc production if feasable.

      Per feasibility:

      Internal opportunities include:
      1. Decreased operating costs
      2. Decreased construction costs
      3. Increased run-of-mine head-grade (this is likely as a bulk sample from Block 1 had a
      10% to 15% higher metal content than reported by borehole assays, probably due to ore
      preferentially washing out of borehole core material during drilling)
      4. Increased rate of production of run-of-mine ore
      5. Decreased dilution of run-of-mine ore
      *6. Increased metallurgical recovery Increasing the Mineral Resource by extending the limits
      of the orebody by exploration drilling / development, and by filling gaps in the known
      orebody information by delineation drilling*
      7. Conversion of Inferred Mineral Resources to Measured or Indicated by infill drilling
      8. Discovery of additional Mineral Resources
      *9. Recovery of gold, lead, and zinc from the ore*

      Met testing showed variability in recovery rates up to 92%. Potential is there to raise the 84% recovery. Ching.

      We have no idea of the amount of zinc and lead byproduct at this time. The drilling was mostly done a long time ago by Silver Standard and/or Gold Fields.

      I hope they are in the process of buying property "in trend" to the west.

      • I am sure that before extensive deliniation of resources near section 1&6 (see page 81 of the feasability report) (south of the Red Hills & Gliem occurances) royalty or other legal agreements will be locked in with the holders of mineral rights.

        I would expect that Aurcana will concentrate on surface occurances to the west until they tie up the mineral rights on adjacent properties. No point in making adjacent sections more valuable by looking for the sources of the mineralization trend before locking up mineral rights.
