    Block 3/Gold exploration in Presidio Co.

    Hi Matt and Tran,

    This prior thread in June is relevent to the topic of gold and other mineralization in the trend. We noted many occurences of gold,lead,zinc,copper and Moly. These all seem to be to the West.
    In different documents the geological descriptions of the Red Hills trend they talk about a dome type structure with down sloping outer fringes. The Presideo and Shafter deposits seem to fit this description to a "T".
    Shafter being a lateral outflow of a pretty good sized chimney/chimneys system of hydrothermal sources ( probably similar to the chimney structures that make up La Negra and massive enough to send truely large flows of metals). The small mines...Gliem, Mackenzie, etc to the west and north of Aurcana's property are probably small spider veins eminating from the source/sources.

    The biggest heat source is the very large copper/Moly intrusion called the Red Hills. (Tosco optioned the property and some surrounding sections)
    Somewhere around that huge moly deposit (heat source evidence) would seem to be the large chimney feeder system.

    "SHAMELESS PLUG" Aurcana aught to pick up a minority interest at least and possibly a majority interest in Tosco to gain access to their property [note also other sections that we have pointed out in other posts].
    Tosco (total market cap of less than 4.5 million), could be purchased for pretty cheap cash/stock investment and would double Aurcana's property control and facilitate other mineral rights transactions and further exploration for the feeder sources.

    Once you have a commercially viable operation as Aurcana has with Shafter these satelite occurances (around old Gliem, MacKenzie, Sullivan mines, old drill hole results,surface sampling,etc.)of gold,lead, zinc, etc. could become viable supplements to mill feeds. As noted in other posts numerous locations around the trend,have gold samples with .33 and .50ozs gold per ton and associated lead,zinc, etc.
    We get excited about contaminated ore with .001 to .003 gold. There are chip samples, old drill cores and mines from around the trend with over 100 times that.

    • New shareholders should read this old thread and follow the sources in various postings.
      My current thinking is that as Aurcana's stock starts to perform here... Lenic will make several acquisitions using a very hot stock.

      Tasco (TSMNF) and several surrounding blocks that Aurcana does not control are probably the hydrothermal sources for the lateral outflows that comprise the Shafter deposit.

      If investers read some of the historical data and information from prior drill results found in many documents they will understand the potential in this area.

      Tasco has a multi billion dollar Moly/Copper resource. Surrounding blocks have many hits for Copper, lead, zinc, silver and gold from widely spaced regional drill holes.

      15-25 million shares would probably buy Tosca and the surrounding blocks with minimal dilution. Billions of Moly and copper plus many exploration targets to feed the Shafter mill.

    • Rholl,

      You are definitely on top of it.

      Tosca expressed an open interest from the outset to partner up with AUN in some fashion to assist in expediting their project.
      Tosca hit seven cents this week-why not just scoop up the property or extend a few million for a percentage?

      I know of an industry insider that will interview Lenic this week and I sent him the following as per your suggestions:

      Hi again xxxxxxxxxxx,

      Could you please ask Lenic Rodriguez if AUN has any interest in picking up the moly/copper project just 7 kms west of Presidio?
      The deposit is owned by Tosca Mining but has drifted to a low of 7 cents with just 40 million shares o/s.
      Tosco has- from their inception- expressed a positive attitude to and possible synergy combo with Aurcana.
      Why not just buy out the majority of shares or make an offer and buy up the deposit and the associated lands that Tosca retain?
      It would be an inexpensive,viable acquisition that will also provide what may prove to be valuable exploration land in and around Presidio/Shafter/Red Hills.
      Many thanks,

    • Here is some of the relevent info from the feasibility study:
      The Gleim Property, south of the Presidio mine, has the potential for structural-related silver and
      gold mineralization. GFMC drill hole SD 264 encountered 7 feet of 10 ounces silver per ton,
      0.07 ounces gold per ton, 4 percent lead and 2 percent zinc at 393 feet. Samples containing high gold
      values were reported taken at the east edge of the Gleim Property.
      Although the original drill core has been lost, the paper drill logs indicate that there is a zone on
      the east edge of the porphyry, which grades 6 percent copper over a vertical distance of 110
      The Red Hills porphyry copper deposit and the Sullivan lead-silver occurrence define the west
      end of the district. However, recent theories about caldera mineral control indicate that potential
      mineralization could exist further to the west. It is believed that possible buried intrusives near
      Red Hills and south and east of Red Hills are the heat source for the hydrothermal solutions
      whose metals formed the currently identified mineral deposits in the district.
      These solutions traversed along regional structures trending N70°E which bound the Shafter-
      Presidio deposit. This regional fabric also hosts a bedded zinc deposit and several high-grade
      lead-zinc veins (often with some minor gold values) with past production at the Montezuma,
      Chinati, Perry, Gliem and MacDaniel workings.
      GFMC never followed up on a large zone of bedded and oxidized zinc mineralization that they
      discovered during their regional drill program. The north-south drill fence with SD 313, SD 316,
      and SD 317 intersected 6 feet of 10 percent zinc mineralization extending 1,200 feet down-dip
      from the Montezuma workings. Drill hole SD 313, located approximately 200 feet south of the
      old mine, encountered two 6-foot zones with 14 percent zinc and the bottom horizon contained
      0.03 ounces gold per ton. A 4 percent to 6 percent zinc zone was also encountered in GFMC’s
      drill holes along strike in fences 2,000 feet to the east and 3,000 feet to the west from the
      Montezuma workings.
      The last 30 years of exploration has encountered numerous gold intercepts of merit, but no
      follow-up work was undertaken. For instance, GFMC drill hole SD 301 encountered 6 feet at
      0.52 ounces gold per ton mineralization at 943 feet near the top of the Permian Mina Grande
      formation (the main ore-bearing sedimentary horizon for the district). SD 301 was not offset with
      additional drilling.
      On both the east and west sides of the Red Hills intrusive, detailed chip sampling of mineralized
      outcrops of the Permian sediments was done by Duval and outlined significant zones of gold
      and silver anomalies. Twenty-eight sets of samples were taken and 18 of these sets had gold
      values that ranged from 0.005 ounces per ton to 0.33 ounces per ton. Silver values in 6 samples
      ranged from 2 to 21.2 ounces silver per ton. On both sides of the draw hosting the MacDaniel underground workings, drifts have been
      worked on strong structural mineralization. Sampling by RGMC on the north-dipping N75°W
      structure indicated plus 6 feet carrying 0.03 ounces gold per ton, 1.2 percent lead, and 13.2
      percent zinc at the surface. These workings were driven prior to World War II, when gold was
      $30 per ounce and zinc was $0.12 per pound.
      Technical Report on Shafter Feasibility Northwest trending structures at the MacDaniel workings and at the Sullivan Mine to the west of
      Shafter demonstrate values of up to 0.30 ounces gold per ton, 2 to 6 ounces silver per ton, 4 to
      20 percent lead, and 3 to 10 percent zinc.
