Sunridge Gold Selects Snowden and GBM to Conduct Prefeasibility Study on the Asmara North Deposits, Eritrea

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Feb. 7, 2011) - Sunridge Gold Corp. (TSX VENTURE:SGC) is pleased to announce that it has engaged Snowden Mining Industry Consultants Inc.("Snowden") and GBM Minerals Engineering Consultants Ltd. ("GBM") to conduct a prefeasibility study on its combined Emba Derho, Adi Nefas and Gupo copper-zinc-gold deposits, now called the Asmara North deposits in Eritrea. Snowden, based in Vancouver, Canada is an internationally respected leader in resource estimation and mine design. Snowden will manage the study assisted by GBM with their engineering design expertise in process plant and infrastructure of mining projects. Their experience will be complemented by Knight Piesold Ltd. ("KP") for tailings facility design and waste management.

The prefeasibility study will consider a centralized process plant using flotation for the recovery of the base metals and will study various mining options over a forecast life of mine of between 10 and 14 years. The study will further investigate process options for the development of a gold recovery plant to process gold mineralized material from the "gold cap" at the Emba Derho deposit, the nearby Gupo gold deposit and other possible nearby surface zones of gold mineralization to enhance economics of the deposits. The completion of this report is expected in the fourth quarter of 2011.

Scott Ansell, VP Projects for Sunridge, stated that, "The Snowden-GBM-Knight Piesold team bring strong mine and process design experience for completion of a successful prefeasibility study. This prefeasibility study will provide the direction of development of the Asmara North deposits to production."

The Asmara North Deposits

The Asmara North deposits are made up of three distinct deposits (full resource tables below):

  • Emba Derho VMS deposit is a large surface minable 62 million tonne copper-zinc-gold volcanogenic massive sulphide (VMS) deposit that was the subject of a positive scoping study by Wardrop Engineering (UK) in 2009.
  • The Adi Nefas deposit located approximately 6 kilometers away from Emba Derho is a much smaller but higher grade zinc-gold-copper VMS deposit.
  • The Gupo gold deposit is approximately 8 kilometers from Emba Derho and is a near-surface structurally controlled gold deposit that was mined during the Italian colonial period.

The Debarwa Deposit Option

The Debarwa deposit is located close to paved road access just 45 minutes drive from the Asmara North deposits. This high-grade copper-gold-zinc VMS deposit is currently in feasibility study. The prefeasibility study to be conducted by Snowden and GBM will examine options to transport ore from Debarwa to a central process plant facility located at the Asmara North project.
