Exploring for gold and base metals in the Abitibi Greenstone Belt
Abitibi has produced more than 180 M ounces of gold and more than 450 Mt of Cu-Zn ore to date
Message: NR results Lynx gold zone Eastford Lake
Rouyn-Noranda, Canada, May 10, 2010. Explor Resources Inc. is pleased to announce the results from a detailed geological review of all
drill cores related to the Lynx Gold Zone on the Eastford Lake Property. The study was prepared by Robert J. Tremblay, P. Geo of Val-d’Or, Quebec. The main vein of the Lynx Gold Zone containing visible gold and appears to strike in a north-north westerly direction and is dipping to the south-south westerly direction. The property is situated in the Kerrs, Warden, Milligan Townships and the Rayner Lake area, south-west of Lake Abitibi, Ontario, 90 km east of the Timmins-Porcupine gold mining camp. The Eastford Lake Property consists of 170 contiguous unpatented mining units for a total of 3,100 hectares. The study focussed on mapping all structural features and their correlation with gold mineralization. As a result of this review, a first interpretative geological map of the gold-bearing zone was developed. Attached, are maps prepared as a result of this study, including a regional geology compilation map (Map No. 1) showing the property at a regional scale and a detailed map of the Lynx Gold Zone (Map No. 2) , illustrating all drill holes along with structural and assay highlights. With regard to the
latter, shears and gold zones are illustrated along each drill hole. Consequently, gold-bearing shears in hole EG-09-23 are at greater depths than those of holes in the central portion of the Lynx Gold Zone. As illustrated on the regional compilation map which incorporates the government’s geology map (ODM Map 22005), the gold-rich shear zone discovered by Explor lies in an area devoid of reliable geological information. In terms of geophysics, the gold zone lies along a northwest-trending magnetic low, within a magnetically high area. The interpretative geological map proposed by Mr. Tremblay suggests that this portion of the property is traversed by a wide corridor of strongly developed northwest-trending shears, which spans a width in excess of 500 m. On a regional scale, it is conceivable that this wide shear constitutes a splay off the gold-rich Destor-Porcupine fault zone to the south. On the government’s regional map, a NNE-trending fault is illustrated southeast of the property, in Munro and Warden Townships. This fault, when projected further to the NNE, intersects the Lynx Gold Zone and then beyond, the gold-rich portion of step out drill hole EG-09-23, drilled some 225 m to the northwest. Though the significance of this cross-cutting fault is unknown at this time, its presence would indicate that it may have served as channel for mineralizing fluids and depositing of some or all of the gold at the Lynx Gold Zone. On the same regional map , a large fold structure is illustrated just northwest of the Lynx
Gold Zone, which would occupy its southern limb. Folding observed in drill core on the Lynx Gold Zone is likely related to this larger fold. Northwest trending shears are strongly altered with sericite, silica and iron carbonates, along with biotite and tourmaline in places. They host fine disseminated pyrite in concentrations which can reach in excess of 10% and weak to moderate gold mineralization, ranging 0.2 to 5.7 g/t. Shears 2 vary from a few metres to more than 10 meters in width, appear to pinch and swell along strike and have a braided pattern, which would suggest merging of some shears in places. Gold-bearing quartz veins enriched in gold, including 16.6 g/t Au over 12 m, are located in a massive gabbro unit wedged between two gold-bearing shears. Current thought is that high grade veins formed in tension fractures (horsetails) or as stockworks resulting from pressures applied by these shear zones. In this regard, the shear lying along the northeast flank of the gabbro, is particularly enriched in gold and may be the as source of the gold concentrated in the gabbro. A cross-cutting east-west fault is indicated just south of the Lynx Gold Zone. It may be part of a more extensive fault system. Such faults, along with the projected NE-trending fault and local folding, could explain the difficulties in linking shears between drill sections in places. In conclusion, the Lynx Gold Zone is marked by many of the characteristics found in major goldmining camps of the Abitibi; these are: - a large tectonic structure, in this case a 500-600 m-wide corridor of strong shearing and alteration, which may define a splay off the gold-rich Destor-Porcupine fault to the south; such splays being long recognized as favourable sites for the occurrence of gold orebodies. - strong silica, sericite and iron carbonate alteration, accompanied locally by strong biotite and tourmaline. - abundant fine siliceous veining and of fine disseminated pyrite in concentrations locally surpassing 10%. - cross-cutting structures (faults), including the northwest-trending shear zone, a projected NNE-trending fault; and of at least one east-west fault. - a large fold structure in proximity; with the Lynx Gold Zone occupying its southern limb. The presence of such folds is usually considered a favourable environment for gold deposition. - wide (> 2-6 m) zones of highly anomalous gold mineralization grading 0.2 to 5.7 g/t associated with the shears described above. - zones of stronger gold enrichment, including 16.6 g/t over 12 m, associated with narrow quartz veining in tension fractures-horse tails and/or stockworks, in a massive gabbro wedged between northwest-trending and gold-bearing shears. The discovery of the Lynx Gold Zone in this area largely unexplored area represents a major technical success. As a possible new gold camp associated with the regional Destor-Porcupine Fault, it will require further systematic drilling to test and improve the proposed geological model, extend the known gold zones and search for new mineralized zones elsewhere on the property. Explor plans a drilling program to commence by the end of May 2010 based on the positive results that were obtained with this study. The program will be designated to determine the strike of the high grade mineralization that was found in Hole #7.
