Eurasian Minerals Acquires Two Gold Projects in Haiti
Overview
The
geology of Haiti is very prospective for epithermal gold-silver as well as
copper-gold porphyry deposits, and consists of preserved remnants of an early
Cretaceous island arc assemblage situated along the northern margin of the
Caribbean Plate. This geologic environment hosts numerous gold and copper
occurrences in Haiti, as well as the Pueblo Viejo deposit in the adjacent
Dominican Republic. Pueblo Viejo has estimated resources and reserves of 15.25
million ounces of gold and 82.8 million ounces of silver (www.barrick.com, July, 2006). However, even
though Haiti's mineral potential is similar to that found in the Dominican
Republic, it has remained under-explored due to the country's historic economic
and political instability.
From
1972 to 1985, in order to assist in developing Haiti's economy, the UNDP
conducted extensive regional geological studies and exploration programs. The
UNDP work is credited with discovering and documenting many gold and copper occurrences,
including the gold mineralization at EMX's new La Mine and Lameil properties.
These two project areas are covered by four EMX Exploration Permits totaling
37,788 hectares of mineral rights.
La
Mine Project
The
La Mine project is centered 15 km south of the Atlantic Ocean and approximately
50 km west of the port city of Cap Haitien. The property consists of one 9,950
hectare Exploration Permit, and includes three separate mineralized prospects
at La Mine, Colombo, and Rivieres des Barres. Gold-silver-barite mineralization
at La Mine was discovered by the UNDP, and explored by Kennecott from 1975 to
1977 (Kennecott results currently unavailable). Mineralization and alteration
occurs over an area extending approximately 7 km north-south, and 1 to 2 km
east-west, exposed through a series of structural windows. The UNDP (1980)
reported that the area contains extensive epithermal mineralization, including
massive barite with gold, massive sulfides, and an extensive epithermal
stockwork-vein zone, with attendant gold-bearing gossans hosted by andesitic to
dacitic volcanic rocks.
Within
the La Mine prospect sub-area, the UNDP (1980) identified all three styles of
mineralization:
-
A zone of steeply dipping massive barite with sulfides and trench sampling results
over 17 meters averaging 7.6 g/t Au, using a 1.0 g/t cutoff.
-
A massive sulfide type of mineralization, including a boulder assaying 8.4% Cu,
1.2% Zn, 4.8 g/t Au, and 64.9 g/t Ag. The source of the boulder has yet to be
identified.
-
The third style of mineralization consists of an extensive stockwork vein zone
that is reported to be 3 kms long (north-south) and approximately 100 to 200
meters wide. The stockwork mineralization was reported to contain 5 to 30%
sulfides composed of pyrite-chalcopyrite-sphalerite.
