Guyana Goldfields Inc. Updates Mineral Reserves at US$1,000/oz Gold Price

TORONTO, Jan. 14, 2016/CNW/ - Guyana Goldfields Inc. (TSX: GUY) ('GGI' or 'the Company') is pleased to update its Mineral Reserves utilizing a gold price of US$1,000per ounce at its Aurora Gold Mine (the 'Project') in Guyana, South America. The previous Mineral Reserve estimate was issued on January 11, 2013utilizing a gold price of US$1,300per ounce. There has been no change to the Mineral Resource model of the Project as previously disclosed on June 24, 2012(the '2012 Resource Estimate'). The updated Mineral Reserves were prepared by Metal Mining Consultants of Denver, Coloradoand SRK Consulting (Canada), Inc. ('SRK') of Vancouver, Canadain accordance with National Instrument 43-101 ('NI 43-101').

The Company produced 35,901 ounces of gold for the year ended December 31, 2015and achieved commercial production January 1, 2016. Total proven and probable Mineral Reserves are 3,042,000 ounces, net of depletion.

(1) CIM definitions were followed for Mineral Reserves.

(2) Mineral Reserves are estimated using a gold price of US$1,000/oz, 5% royalty and an average metallurgical recovery of 97.0% for saprolite and 94.4% for fresh rock material.

(3) Mineral Reserves are based on a cut-off grade of:

- Open Pit Vein saprolite cut-off grade of 0.43 g/t Au - Upper saprolite cut-off grade of 0.41 g/t Au

- Open Pit Fresh rock cut-off grade of 0.75 g/t Au - Fresh rock Rory's Knoll cut-off grade of 0.64 g/t Au

- Underground 1.62 g/t Au.

(4) Mineral Reserves include:

- Open pit: ore loss of 5% and dilution of 4% to 23% at 0.1 g/t Au.

- Underground: ore loss of 12% and dilution of 21% at 1.43 g/t Au.

(5) Totals may not add due to rounding.

Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. All figures have been rounded to reflect the relative accuracy of the estimates. The cut-off grades are based on a gold price of US$1,300 per ounce and metallurgical recoveries of ninety-five percent for saprolite and fresh material. Open pit resources are reported within conceptual optimized open pit shells, whereas underground resources are external to these. Open pit resources are reported at a cut-off grade of 0.30 and 0.40 g/t gold for Saprolite and Fresh rock respectively, whereas underground resources are reported at a cut-off of 1.8 g/t gold.


As of December 31, 2015, 27% more ounces of gold were contained in the ore mined than were predicted by the ore reserve model for the Project.

Scott A. Caldwell, President & CEO, stated 'Results to date demonstrate a conservative ore reserve model and the high grade, profitable nature of the Aurora Gold Mine.'

Resource Upside Potential and Opportunities

The updated Mineral Reserves documented herewith does not consider material from the following underground Mineral Resources as defined in the 2012 Resource Estimate:

  • 1.69 million ounces of gold @ 3.67g/t in the indicated category at Rory's Knoll
  • 1.22 million ounces of gold @ 4.27g/t in the inferred category at Rory's Knoll
  • 787,000 ounces of gold @ 3.90g/t in the indicated category in the satellite deposits
  • 341,000 ounces of gold @ 3.64g/t in the inferred category in the satellite deposits

The Company will continue to evaluate the integration of some of these additional ounces into the ongoing mine plan. The majority of these ounces are found below the pit shell at Aleck Hill, Mad Kiss and at Rory's Knoll below a depth of -770 meters below sea level. The mine plan includes excess mill and equipment capacity later in the mine life that is expected to provide throughput flexibility for the mining and processing of the additional resources.

Management estimates from internal modelling that with a higher gold price of approximately US$1,250per ounce, an additional 1.5 million economic ounces of gold can be returned back into the mine plan.

2016 Exploration

The 2016 exploration program is focused on exploration targets within a close proximity radius of the Aurora Gold Mine as potential sources of new open pit feed. There are several drill ready targets proximal to the Aurora Gold Mine of which the Iroma prospect is the most highly significant. The Iroma Prospect is located approximately 10 km northeast of the Aurora Gold Mine with a total land area of approximately 120 square km. Baseline exploration work including deep saprolite drilling has delineated a coherent 8.5 km by 0.5 km gold anomaly in soils. Drilling of this area is the prime target for the year. An exploration budget of US$3Mhas been allocated for 2016.

Updated Technical Report

GGI plans to issue the key findings summary of an updated feasibility study for the Project (the 'Updated Feasibility Study') on Monday, January 18, 2016which will reflect an extended open pit mining scenario while deferring the underground production until later in the mine life based on a gold price of US$1,000per ounce. In addition, the complete Updated Feasibility Study will be filed the same day on SEDAR at as well as on the Company website at

Mineral Resources and Mineral Reserve estimates have been prepared in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum's ('CIM') 'CIM Definition Standards -- For Mineral Resources and Mineral Reserves' adopted by the CIM Council on May 10, 2014. Proven and probable Mineral Reserves are the economically minable portions of the measured and indicated Mineral Resources after the application of appropriate modifying factors. Such factors include, but are not restricted to, mining, processing, metallurgical, infrastructure, economic, marketing, legal, environmental, social and governmental factors.

Information Concerning Estimates of Mineral Reserves and Resources

The Mineral Reserve and Resource estimates reported in this press release were prepared in accordance with NI 43-101, as required by Canadian securities regulatory authorities. For United Statesreporting purposes, the United States Securities and Exchange Commission ('SEC') applies different standards in order to classify mineralization as a reserve. In particular, while the terms 'measured,' 'indicated' and 'inferred' Mineral Resources are required pursuant to NI 43-101, the SEC does not recognize such terms. Canadian standards differ significantly from the requirements of the SEC. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories constitute or will ever be converted into reserves. In addition, 'inferred' Mineral Resources have a great amount of uncertainty as to their existence and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian securities laws, issuers must not make any disclosure of results of an economic analysis that includes inferred Mineral Resources, except in rare cases.
