Copper Duke Exploration Yields Significant Gold Values And Expands Area Of Known Mineralization
Vancouver, BC, April 12, 2006 - Dynasty Metals & Mining Inc. (TSXV: DMM; the “Company”) reports that ongoing rock channel sampling at the Huato area of its Copper Duke Project in southern Ecuador has returned significant gold and silver values. Exploration has also identified an area of disseminated gold mineralization in stockwork and a large area of highly anomalous gold in soils.
Copper Duke is a 10 km x 5 km porphyry-style system that lies within the Company’s wholly-owned 90 km x 20 km Dynasty Copper-Gold Belt, in southern Ecuador. It is one of eight such systems, with associated large quartz-sulphide vein swarms and stockworks, known to be hosted by the Dynasty Copper-Gold Belt.
Within Copper Duke, the “Huato” and “Blanquillo” target areas, located 6 km apart, are described as a strongly altered (propylitic) Tertiary andesitic volcanic sequence that has been intruded by a number of porphyries with epithermal vein swarms. For results of previous exploration, see the Company’s news release of January 23, 2006.
Assay results have now been received from 61 channel rock chip samples taken over an area 3 km x 2.5 km on epithermal vein swarms at Huato. Results range from 34.0 grams per tonne (“g/t”) gold to 0.1 g/t gold and 249 g/t silver to 0.4 g/t silver over widths of 2.2 metres (“m”) to 0.2 m. The average sampled width of mineralization is 0.8 m. Significant values are tabulated below:
Gold in Stockwork and Soils
Separately, mapping and channel sampling in the south-east of Huato has identified a large, disseminated gold stockwork that appears to be closely related to the veining described above. To date, 12 widespread channel samples taken from 300 m x 150 m of the stockwork have averaged 1.1 g/t gold from an average sample width of 6 metres.
The stockwork occurs within a 1500 m x 600 m copper-gold-molybdenum anomaly in leached altered porphyritic andesite. Initial channel sampling of this anomaly has returned average assays of 0.1% copper and 20 parts per million (“ppm”) molybdenum over an average width of 10 m from 25 samples.
In addition to the new stockwork, soil sampling by the Company has identified anomalous gold in a concentrations in excess of 40 parts per billion (“ppb”) over an area approximately 1.8 km long and up to 1 km wide. Broad, high-grade zones within this larger anomaly were identified with grades averaging 585 ppb gold over a width of 400 m. Bedrock mapping suggests that this gold soil anomaly is underlain by multiple, gold-bearing vein swarms hosted by volcanics.
The anomaly, which abuts the area of anomalous copper-gold-molybdenum, was defined by 254 soil samples from a 200 m x 100 m grid over an area of approximately 6 square km. Ten soil lines, each 2.5 km in length, were sampled at 100 m intervals along their length.
With these positive soil results, an additional three soil lines are currently being sampled. Further channel sampling and trenching are expected to increase the size of the anomalies at Huato.
Quality Control and Assurance
Exploration of the Company’s properties is under the supervision, of Greg Whitfield, the Company’s Exploration Manager and a “qualified person”, as defined by National Instrument 43-101. Mr. Whitfield is responsible for the preparation of technical information in this news release. Samples are sealed on the property and shipped to the BSI Inspectorate laboratory in Quito, Ecuador for preparation. Sample pulps are shipped by BSI Inspectorate to its laboratory in Lima, Peru for gold fire assay, silver and multi-element ICP analysis.
