Dynasty Metals And Mariana Resources Join Forces To Explore The Macara Gold Project In Southern Ecuador

May 31st, 2007

Vancouver, B.C., May 31, 2007 - Dynasty Metals & Mining Inc. (TSXV: DMM, the “Company” or “Dynasty”) has signed a binding letter of intent (“LOI”) with Mariana Resources Ltd. (AIM: MARL, “Mariana”) to jointly explore and develop 8,641 hectares of adjacent mineral concessions held by them in southern Ecuador.

The joint venture project area combines Dynasty’s 3,408 hectare (“Ha”) “Chorrera” concession (representing less than 4% of its Dynasty Copper-Gold Belt) and Mariana’s 5,234 Ha “Macara”, “Madeira Fina”, “Uña de Gato” and “Ceibo Quemado” concessions. The project is located approximately 10 kilometres west of the town of Macara, in Loja Province.

The companies will each hold a 50% participating interest in the joint venture - to be called the “Macara Joint Venture” - and will jointly fund it. Mariana will be the operator during the exploration phase and Dynasty the operator during any resultant development and mining.

Dynasty President, Rob Washer, commented: “John Sutcliffe and his team have been active in Ecuador for some time. They have an excellent understanding of the country and its geology. This deal increases our exposure to mineral discovery at the southern tip of our Dynasty Copper-Gold Belt and advances exploration in an area that we would not otherwise be focused on at this time. And it does so without deflecting us from our principal projects.”

About the Macara Joint Venture Project

Reconnaissance work conducted by Mariana in the area of the joint venture concessions has identified high-grade stratabound gold mineralization, with values of up to 42 g/t gold in shallow artisanal workings that straddle the concession boundary between Mariana’s Macara and Dynasty’s Chorrera concessions.

Outcrop in the area is restricted, but gold mineralization observed to date is present in at least two gold-bearing strata that range in thickness from 1 metre to 2 metres, hosted by calcareous volcaniclastics of the Celica Formation. The mineralization is unusual and believed to be porphyry-related skarn-type. The area around the old workings presents an immediate drill target.

The LOI contains terms governing the operation of the joint venture that are consistent with industry standards in a structure of this kind. The initial exploration budget is expected to be in the range of US$300,000, with work to commence immediately.

A plan showing the Macara joint venture concession holdings will be available shortly on the Mariana website www.marianaresources.com.
