high-sulphidation epithermal gold system |
History: |
The Caldera project was discovered in 2007 during Almaden`s regional exploration program in Mexico. The project is located in Puebla State less than 150 kilometers from the Company’s Caballo Blanco project. |
Current work |
Almaden has initiated an 2008 exploration program on the Caldera including geologic and alteration mapping, rock, soil and stream sediment geochemical sampling and IP geophysical surveys. |
Geology: |
high-sulphidation epithermal gold system |
History: |
The Campanario Property, located in Oxaca State, was identified and acquired entirely by staking during a reconnaissance program carried out by Almaden in 2004. |
Past work includes: |
geological mapping, geochemistry, IP surveys |
Highlight results: |
Almaden completes a work program consisting of 18 rock-chip samples of subcrop and float range from 7 to 3,590 ppb (parts per billion; 1000 parts per billion is equivalent to 1 parts per million or 1 gram per tonne) gold and averaged 409 ppb gold. A preliminary four line soil sampling program was carried on 100 meter spaced lines with samples taken every 25 meters. The samples have returned gold values from 10 to 525 ppb gold, averaging 65 ppb gold. |
Geology: |
high-sulphidation epithermal gold and silver system |
History: |
The Cerro Colorado Property is 100% owned by Almaden through staking. The colourful hydrothermal
alteration on the Cerro Colorado was recognised by Morgan Poliquin during a regional helicopter exploration program. |
Past work includes: |
geological mapping, geochemistry, IP surveys |
Geology: |
low-sulphidation epithermal gold system |
History: |
The Fuego Property was recognised
during an Almaden helicopter reconnaissance program for copper porphyry
systems in Mexico. Visible gold was recognised
in several hand specimens collected on the property, which led Almaden to acquire a 100% interest
by staking in 2003. |
Past work includes: |
geological mapping, geochemistry, IP surveys, and limited drilling. |
Highlight results: |
Diamond drill results from Horseshoe Gold's 2005-2006 Program include 6.13m of 1g/t gold (HOLE 2), 0.39m of 4.26g/t gold and 100g/t silver (HOLE 3), and 1.10m of 1.65g/t gold and 103g/t silver (HOLE 8). Almaden believes that the drilling intersected the vein at very shallow levels and that the results are encouraging for high grade gold and silver at greater depths. |

History: |
The Tuligtic project was recognised during a helicopter reconnaissance program in 2005. The property is located approximately 100 kilometres north of Puebla and 150 kilometres west of Mexico City and is covered by a 5,000 hectare claim staked and held 100% by Almaden.
|
Past work includes: |
geological mapping, geochemistry, and IP surveys. |
Highlight results: |
The rock and soil sampling and IP geophysical program has defined a large porphyry copper-gold target that has never been drill tested. In addition a low-sulphidation vein system has been identified on the property adjacent to the porphyry target. |
Geology: |
copper-gold porphyry |
History: |
The San Carlos project is located within a north-south trending belt of alkalic intrusive rocks in eastern Mexico. A mining camp was active on part of the property during the late 1800s and early 1900s in a zone now know as the San Jose Area. |
Past work includes: |
geological mapping, geochemistry, IP surveys, and limited drilling. |
Highlight results: |
A large area of porphyry-style Cu-Mo-Au mineralization and alteration as well as and high-grade zinc mineralization likely associated with sulphide, replacement-style mineralization has been identified. Eleven holes have been drilled on the property for a total of 2,378 meters. The highlights include 12.11 meters of 0.11% copper and 247.50 metres of 0.04% copper and 0.008% molybdenum within the mineralized intrusive. Highlights of drilling which targeted skarn mineralization include 1.24 g/t gold and 1.26% copper over 2.80 metres and 6.6 g/t gold over 1.4 meters.

silver-lead-zinc replacement sulphide |
History: |
The 100% owned Santa Isabela property covers a roughly 14,000 hectare area in Coahuila State, Mexico. The project was identified
by Almaden during a regional helicopter-borne prospecting program and covers
a low-lying ridge located within 50 kilometers of the large Penasquito
Ag-Pb-Zn deposit owned by Western Silver Corporation and the
historic Concepcion del Oro polymetallic mining camp. |
Past work includes: |
geological mapping, geochemistry, IP surveys, and drilling. |
Highlight results: |
Only two diamond drill holes have been drilled for a total of 765.15 meters in two separate drill programs. Both drill holes intersected anomalous silver, lead, zinc values. |
