Eurasian Minerals Discovers Two New High-Grade Copper-Silver-Gold Prospects at Treuil Property, Hait
Eurasian Minerals Inc. (the "Company" or "EMX") (TSX VENTURE:EMX) is pleased to announce the discovery of the Chardonnay and Bordeaux high-grade copper-silver-gold prospects at the Treuil project in northwest Haiti. At Chardonnay, 63 reconnaissance rock samples taken over a 1.25 square kilometer area returned an average grade of 4.00% copper, including vein samples reporting 24.30% copper and 201 g/t silver, and 1.66% copper and 90.7 g/t gold. Rock sampling over a 1.9 square kilometer area at Bordeaux returned an average grade of 2.66% copper, including a vein sample returning 13.10% copper, 98 g/t silver and 1.7 g/t gold. The Chardonnay and Bordeaux prospects, taken together with the Champagne discovery reported previously, outline an 18 square kilometer district scale exploration target with consistent rock sample copper grades of over 1%, and associated gold grades increasing towards the south. EMX is exploring Treuil with Newmont Ventures Limited ("Newmont" or "NEM"), a wholly-owned subsidiary of Newmont Mining Corporation (NYSE:NEM), as part of its Regional Strategic Alliance exploration program (see Company news release dated April 28, 2008). Please see the attached map and the Company's website at www.eurasianminerals.com for more information.
Overview. The Treuil license contains 88 square kilometers of mineral rights adjacent to, and contiguous with, the Company's La Mine project on the north. EMX has reported high-grade copper-silver mineralization at the Champagne prospect, with trench sample results including 14 meters averaging 19.15% copper and 140 g/t silver (see Company news release dated October 7, 2008). The copper-silver mineralization at Champagne occurs in a series of sub-parallel structural zones that have been documented over a 1.3 kilometer long north-south trend.
EMX's recent mapping and sampling has identified additional high-grade copper-silver and gold occurrences within a six kilometer by three kilometer northwest trending area of mineralization and alteration. This work resulted in the discovery of the Chardonnay and Bordeaux prospects. Chardonnay consists of structurally-controlled, high-grade copper-silver mineralization on trend with, and 2.5 kilometers south-southeast of Champagne. Notably, in addition to copper-silver mineralization, Chardonnay samples have returned consistently elevated gold assays. Together, Champagne and Chardonnay occur within a six kilometer long, north-northwest trending structural zone that hosts more than 380 recently documented copper-silver-gold occurrences. The Champagne-Chardonnay trend is open for extension along strike to the northwest and southeast. A second area of concentrated high grade copper-silver-gold occurrences has been identified at the Bordeaux prospect, located 1.5 kilometers northeast of Chardonnay, and two kilometers southeast of Champagne. Further work is necessary to delineate the extent of the mineralized systems at these two new prospects. However, it is apparent that Champagne and Chardonnay are within the same mineralized structural trend, and Bordeaux may represent a second, sub-parallel trend. Taken together, the Champagne, Chardonnay, and Bordeaux prospects have significant exploration potential as district scale, high-grade copper-silver-gold targets.
Chardonnay Copper-Silver-Gold Prospect. The mineralization at Chardonnay consists of copper-silver-gold mineralization hosted within variable, but generally north-northwest trending fault zones, and in adjacent deformed andesitic wall rocks. This is a similar geologic setting to mineralization found at the Champagne prospect. Mineralization also occurs in two shallow-dipping fault zones, each up to 10 meters wide, that are in turn cut by the steeply dipping, north-northwest mineralized faults. Copper mineralization occurs as primary chalcocite +/- bornite +/- chalcopyrite in veins and as disseminated mineralization in the andesitic wall-rocks. The terrain is steep and densely vegetated, with samples collected from the available outcrops by EMX field crews. These outcrops frequently consist of resistant vein material, and a limited amount of wall rock. Initial channel and panel samples have identified high-grade copper-silver-gold mineralization in several areas at Chardonnay.
EMX collected 63 rock samples over a 1.25 square kilometer area that averaged 4.00% copper (min equals 0.004, max equals 24%), 42 g/t silver (min equals 0.05, max equals 211 g/t), and 4.2 g/t gold (min equals 0.001, max equals 90.7 g/t). Of these 63 samples, 59% assayed more than 1% copper, 43% over 0.5 g/t gold, and 35% better than 30 g/t silver. A table of significant Chardonnay sample results is listed below. Of note, the wall rock can also host high-grade mineralization, as highlighted by panel sample 10255 in the table. For table click here.
