Minco Mining and Metals Corporation updated its exploration activities on its gold projects on the Yangshan gold belt in Southern Gansu Province, China. A regional mapping and detailed stream sampling program was completed over an area of 913 Sq km with 3036 stream sediment samples collected. The program is focused on 13 wholly owned exploration licenses in the Qinling Gold Triangle on or near the Yangshan Gold Belt. 45 zones anomalous in gold (Au), silver (Ag), antimony (Sb), or arsenic (As) have been identified in three groupings of licences.
The geochemical data in Minco's stream sediment sampling program at the northeast extension of the Anba gold deposit, outlines 20 composite anomalies of Au, As, Sb or Ag which have been delineated in the survey area. The gold anomalies coincide with strong As and Sb values located in a Devonian clastic rock unit closely associated with a regional arcuate fault structure. The structural and geological setting and geochemical features of these anomalies are comparable to those of the known areas of gold mineralization along the Yangshan gold trend.
14 composite anomalies in stream sediment samples have been delineated in the Yejiaba project area, a belt parallel to and north of Yangshan. The largest composite anomaly, the Madigou anomaly, is 23 square kilometres in area and characterized by coincident Au, Ag, As, and Sb values.
Xicheng Project Area is located at the east extension of the well-known Xicheng Pb-Zn metallogenic belt northeast of Yejiana. 11 composite anomalies have been delineated in the project area. The largest anomaly is about 16 square kilometres in area and consists of coincident Au, Ag, Pb and Zn values. For the Xicheng East area as a whole, good potential for gold, silver, lead and zinc is indicated.
Ten of the most significant anomalies characterized by coincident Au, Ag, As & Sb values in favourable geological terrains have been selected for the first-round follow-up. The follow-up program has been initiated and will be completed in approximately mid August. Targets generated by the detailed follow-up programs will be trenched and/or drill tested in the second half of 2006.
The samples above were analyzed for Au, Ag, As. Sb, Bi, Cu, Pb, Zn, W, Mo, Ba and Hg at the central lab of the Institute of Geophysical and Geochemical Exploration in Langfang, Hebei province. Analytical quality was controlled by inserting reference samples and duplicate samples in each 20-sample batch.
The Company also acknowledges the resignation of Mr. Robert S. Tyson as Vice President Corporate Development and wishes to thank Mr. Tyson for his contributions to the Company during his tenure.
