Guyana Goldfields Inc. Provides an Update on the Aurora Gold Project and Continues To Expand the Project Team

TORONTO, June 13, 2012 /CNW/ - Guyana Goldfields Inc. ("GGI" or "the Company") (TSX: GUY) is pleased to announce that the Company is on schedule to deliver a revised resource estimate for the Aurora Gold Project by the end of June 2012 and has also made additions to the Aurora Bankable Feasibility Study ("BFS") Project Team.

Revised Resource Estimate

Guyana Goldfields is on-track to publish by the end of this month an updated resource estimate for the Aurora Gold Project which will include an additional 171 drill holes totalling 56,336.52 metres completed from May 31, 2011 up to the end of April 30, 2012. The revised estimate will update and improve the geological model, upgrade inferred ounces to the measured & indicated categories, and provide guidance on depth extensions from previously defined mineralized structures (see press release dated September 9, 2011). The Aurora Gold Project currently has 5.71 million ounces in the measured & indicated categories (47.040 million tonnes at a grade of 3.83 g/t) and 1.17 million ounces in the inferred category (9.97 million tonnes at a grade of 3.63 g/t).

Bankable Feasibility Study ("BFS")

The Company intends to issue a revised BFS by the end of this year. The study is expected to take a staged development approach, with oxidized ore being mined and processed over the first 2 years of operations, followed by a hard rock open pit and underground mining scenario.

The revised BFS will eliminate the vertical shaft component of the initial Feasibility Study issued earlier this year (see Technical Report on SEDAR dated April 9, 2012) and will concentrate on mining the deposit from surface to approximately 750m vertical depth utilizing a ramp. The plant and processing operations are also expected to be designed to fully optimize project economics specifically targeting significant improvements to initial capital costs of the project as well as ongoing operating costs. Management believes that the Aurora production timeline can also be significantly shortened.

The Company has also engaged two experienced project managers for the BFS, Mr. Deepak Malhotra and Mr. Donald Elkin, who have been working closely with the Aurora Project Team over the last two months refining an optimized approach to the development and construction of the Aurora Gold Project with specific emphasis on reducing initial capital costs.

Mr. Malhotra possesses 40 years of project design and assessment experience with various mining projects around the world in a variety of jurisdictions.  He is currently the President of Resource Development Inc., and holds a Ph.D. in Mineral Economics and a M.S., Metallurgical Engineering from the Colorado School of Mines, Colorado and a B.S. in Metallurgical Engineering from the Indian Institute of Technology, India.

Mr. Elkin encompasses 50 years of experience in optimizing mine plans and ore resource calculations. He is the President and Principal Geological Engineer of Mine Reserves Associates Inc, a consulting firm in the areas of deposit modeling, resource and reserve estimation and mine planning.  Donald holds a B.S. of Engineering Mathematics and a B.S. of Geological Engineering both from the University of Arizona.

The Aurora Project Team has engaged the following engineering firms to assist in the preparation of the revised BFS:

• Tetra Tech (Denver), a leading provider of consulting, engineering, and technical services worldwide, will assist with the process design and civil works, as well as be responsible for the overall compilation of the BFS.
• SRK Consulting (Toronto), will be overlooking the open pit and underground mine design based on the blast-hole open stoping mining method.
• SRK Consulting (Vancouver), will run a parallel study to their Toronto based colleagues examining a possible alternative underground mining method using Sub-Level Retreat ("SLR"). A scoping study on SLR has been completed and initial results have indicated that this method may have the potential to significantly decrease underground mining costs.

The Company intends to release the revised, fully optimized BFS by the end of 2012. The Company continues to carry out off-site and on-site civil and infrastructure works that are critical to mine development and construction.

Patrick Sheridan, Jr., CEO states, "We are pleased with the progress and preliminary directions of the BFS and strive to remain on track to delivering all milestones. We hope to make further announcements on the progress of the staged development program for Aurora in due course. Deepak and Don share an extensive amount of knowledge and experience and we are excited to have them join our existing project team. Their technical expertise coupled with a vast understanding of project economics and practicalities are extremely valuable to both the BFS and the future of the Aurora mine as a whole as we demonstrate the true optimized value of Aurora."
