DMM - Dynasty Significantly Increases Gold and Silver Resource Estimate at Dynasty Goldfield Project

Dynasty Metals & Mining Inc. (TSX: DMM, the "Company") has received a new, independent estimate of gold and silver resources for the Dynasty Goldfield project in southern Ecuador.

Vancouver, BC (PRWEB) November 20, 2007 -- Dynasty Metals & Mining Inc. (TSX: DMM, the "Company") has received a new, independent estimate of gold and silver resources for the Dynasty Goldfield project in southern Ecuador.

The new resource estimate is based upon the results of the Company's continuing trenching and drilling program in the Cerro Verde, Papayal and Trapichillo areas of the Dynasty Goldfield. The database includes a total of 5,473 assays from 20,499 metres (152 drill holes) of diamond drilling and 6,678 metres of trenching from 967 trenches.

A technical report supporting the new resource estimate is being prepared by Allen J. Maynard, BAppSc(Geol), MAIG, MAusIMM, an independent, "qualified person", as defined by National Instrument 43-101 ("NI 43-101"). Upon electronic filing with the Canadian Securities regulators and on the Company's website, it will be available for viewing at http://www.sedar.com and http://www.dynastymining.com .

Company President and CEO, Robert Washer, commented: "We are pleased with the results of this independent assessment. The Dynasty Goldfield is a new discovery, associated with one of eight porphyry-style exploration targets that we have identified to date in the Dynasty Copper-Gold Belt. Before our initial campaign on the Dynasty Goldfield, none of these targets had been previously drilled, or even systematically explored. This report demonstrates both the potential of the belt and our ability to turn exploration dollars into ounces in the ground.

With gold and silver occurring at surface along strike and with the ongoing trenching program having identified additional large areas of high grade gold and silver targets we expect that our ongoing exploration will increase the estimated resources at the Dynasty Goldfield and demonstrate the potential for underground and bulk tonnage mining".

The Dynasty Goldfield

The Dynasty Goldfield consists of seven concessions with mapped and sampled veins and stockworks that cover an area of approximately 30 km² within the Company's 100% owned Dynasty Copper-Gold Belt, in south-western Ecuador. It includes the Papayal, Cerro Verde, and Trapichillo mineralized hydrothermal vein systems, which lie on a north east trend over a distance of 13 kilometres. In April of 2006, the Company disclosed its first NI 43-101 compliant mineral resource estimate on Dynasty Goldfield. The estimate was supported by a technical report dated April 21, 2006 prepared by Allen J. Maynard, BAppSc(Geol), MAIG, MAusIMM, an independent, "qualified person", as defined by NI 43-101. The technical report is available on SEDAR. A summary of the resource estimate appears in Table 2 below:
