Golden Dawn Renews Mine Evaluation for Silver and Gold at May Mac Mine Based on High-Grade Samples from the Number 6 Adit, Boundary Falls Property, Greenwood B.C., Canada(May 02, 2011)
Vancouver, May 2, 2011 GOLDEN DAWN MINERALS INC. (TSX-V: GOM, FRANKFURT: 3G8) Wolf Wiese is pleased to announce the assay results from a recent sampling of the #6 Adit of the May Mac Mine. Four character samples taken during an inspection by Wayne Ash P.Eng, a mining engineer, have returned high precious and base metal values. The May Mac gold/silver Mine is, located approximately 2 km south of the City of Greenwood, B.C. The four character samples returned values ranging between 10.4 to 84.2 g/t gold and 404 to 2,080 g/t silver from the veins and wall rock materials within the #6 Adit as detailed below.
SAMPLES 1-4 ASSAY RESULTS
Character rock grab sample of near-massive sulfide from the A-A” Stope, but finer-grained than Sample #1; assay 84.2 ppm Au (2.45 opt Au), 2080 ppm Ag (59.5 opt Ag), 24.3% Pb, 9.01% Zn, and 20.4% Fe.
Character rock grab sample of massive sulfides left in A-A” Zone, containing coarse-grained galena and massive pyrite; assay 0.93 ppm Au (0.027 opt Au), 844 ppm Ag (24.6 opt Ag), 19.75% Pb, 3.55% Zn, and 30.5% Fe.
Character rock grab sample of quartz vein 25 cm width, (which was apparently considered too narrow to warrant mining in 1974), with central band of near-massive pyrite, plus galena and sphalerite; assay14.3 ppm Au (0.417 opt Au), 404 ppm Ag (11.8 opt Ag), 7.48% Pb, 5.35% Zn, and 15.0% Fe.
Character rock grab sample taken of a quartz vein which horse-tailed out into the right rib of the drift and having a width of approximately 1.2 meters; assay 10.6 ppm Au (0.31 opt), 421 ppm Ag (12.2 opt), 6.53% Pb, and 3.23% Fe.
The current inspection provided a preliminary assessment of the potential for further development of the May Mac Mine and for investigation of the surrounding exploration potential of the Boundary Falls Property. The Boundary Falls Property is part of Golden Dawns Greenwood project, which also includes the Wild Rose Property contiguous to the North and the Tam OShanter Property contiguous to the North West of the Wild Rose Property.
The May Mac Mine lies on the Northwest portion of the Boundary Falls Property. The mine is 2 km south east of the target area on the Wild Rose Property where the company recently completed a phase one, 12-hole drill program, and anticipates further drilling upon completion of a current groundwork program. The May Mac Mine area contains a permitted 120 ton/day gravity and flotation mill with tailings facility which was in operation intermittently until the late 1990s.
During Mr. Ashs visit, only the #6 Adit was available for inspection. Several undeveloped veins were noted which horse-tailed out into the hanging wall of the adit. Mineralization within the veins consists of wisps and lenses of pyrite and galena, although sulfide wisps also occur in the adjoining sheared argillite. The shear zones appear to be open along strike and down dip, yielding exploration potential for an anticipated work program.
The history of the May Mac Mine began with intermittent development and mining between 1904 and 1983, producing some 3,500 tons of ore averaging approximately 5.2 g/t Au (0.15 opt Au) and 238 g/t Ag (6.9 opt Ag). Production was directly-shipped to the COMINCO Smelter at Trail, B.C. Note that all data, other than the assay results of the current sampling, conducted by Wayne M. Ash, P. Eng., are historical in nature, may not be complete, have not been verified.
The Upper Skomac veins are hosted within a thinly-bedded carbonaceous sheared argillaceous zone, with a strike of 310? to 320? azimuth, and dips of 40? to 60? northeast. The shear zone appears to vary between three and four meters wide, but may be wider. Mineralized white quartz veins occur within the shear zone. The main vein varies from 0.3 to 3.0 meters in width, averaging 0.9 meter, but narrow, discontinuous veins and veinlets tend to occur throughout the full adit width.
The Upper May Mac Mine is accessed by four adits (#4, #5, #6 and #7). The #4 Adit was apparently driven in 1904 and is reported to have produced some 890 tons grading approximately 3,400 ppm Ag (100 opt Ag) between 1904 and 1937. This is also historical information. The #5 Adit, driven some 12 m lower in elevation in 1962, was developed and stoped out to the #4 level. Access is presently barred by caving. The #6 Adit, driven in 1974 and collared some 30 meters below the #5, was the longest adit developed. It was driven along the main structure for some 215 meters and encountered four mineral zones. During the productive years, the four zones, including the AA, A, B & C zones, and constituting approximately 40% of the adit length, were considered sufficiently wide and high enough grade to be economically mined. Note, however, that due to the absence of an assay office, fire assays were seldom conducted. The grade of the material to be mined was assessed visually. The drift backs (adit ceiling) or ribs (adit walls) have apparently never been sampled, and represent an immediate target for evaluation.
In 1976, the #7 Adit was driven at an elevation of some 60 meters below the #6 Adit, but failed to encounter significant mineral. It has since been determined that this adit was driven on a barren vein, some 30 to 50 meters into the footwall of the main, productive vein, leaving the main vein as a prominent exploration and development target.
During the visit, the four character mineral samples were taken by Mr. Ash P. Eng., and were personally transported by him to ALS Chemex Labs in North Vancouver for analysis. Pursuant to the encouraging assay results and the availability of a flotation mill with tailings facility on site, Mr. Ash P.Eng. has recommended a program to further develop the May Mac Mine.
The entire Boundary Falls Property has undergone various exploration programs over the years. The most recent work was a Helicopter TEM EM-MAG survey which yielded anomalies which are coincident with previous VLF surveys and geochemical (soil sampling) surveys. This group of survey results has delineated targets of interest that may be separate mineralization from the May Mac vein systems or perhaps be related to these veins. This is particularly of interest in the area of about 400-1000 meters to the south of the May Mac Mine, where several small adits follow high grade veins in an area coincident with a MAG-EM anomaly. At this time both Mr. Ash P.Eng. and APEX Geoscience Ltd. are compiling the necessary data for further evaluation and work recommendations.
The reader is cautioned that historical data is not confirmed, and such historical data has not been verified. There are no known mineral resources on the property, and there can be no assurance that any mineral resources will be discovered on the property and, if discovered, there is no assurance that any mineralization may be economically extracted.
