Cerro Prieto - Project Status Update

Cerro Prieto is located in northern Sonora, Mexico within 150 kilometers of Goldgroup's Cerro Colorado gold mine. The Company has been advancing the development of the Project. On August 8, 2013, the Company announced an updated National Instrument 43-101 ("NI 43-101") Measured and Indicated and Inferred mineral resource estimate for the Project. Please refer to the NI 43-101 technical report prepared for the Company by Duncan Bain Consulting Ltd. and Giroux Consultants Ltd. titled "Report on the 2011-2012 Exploration Program including an Updated Resource Estimation on the Cerro Prieto Project, Magdelena de Kino Area, Sonora State, Mexico" dated June 10, 2013 and filed on SEDAR on August 8, 3013. Highlights of the NI 43-101 mineral resource estimate include:

• The Measured Mineral Resource category was comprised of 1.18 million tonnes grading 1.56 grams per tonne (g/t) gold, 30.28g/t silver, 0.15% lead and 0.33% zinc for a total of approximately 59,000 ounces of gold.
• The Indicated Mineral Resource category was comprised of 4.92 million tonnes grading 1.03g/t gold, 22.12g/t silver, 0.32% lead and 0.80% zinc for a total of approximately 163,000 ounces of gold.
• The Inferred Mineral Resource category was comprised of 5.025 million tonnes grading 0.75g/t gold, 20.62g/t silver, 0.49% lead and 1.28% zinc for a total of approximately 121,000 ounces of gold.
• The Company is pleased to announce that site construction and development efforts are well underway at the Project and include the following highlights:
• Site access road capable of supporting heavy truck traffic.
• Acquisition of process water by utilizing a well to drain the old mine workings.
• Metallurgical lab and a column leach testing facility.
• Construction of a trial leach pad, ponds and a Carbon Adsorption Plant.
• Crushing and metallurgical testing to optimize recovery rates.
• The Company intends to begin small-scale trial mining and leaching in the fourth quarter of 2013 in order to determine the ideal parameters to put the Project into production in 2014.

The Company wishes to make clear that it is not basing its production decision on a preliminary economic assessment demonstrating the potential viability of mineral resources or a feasibility study of mineral reserves demonstrating economic and technical viability, and as a result there is increased uncertainty and multiple technical and economic risks of failure which are associated with this production decision.

Loan Facility Status Update

Goldgroup is also pleased to announce that it has closed a CDN$4.25 million senior secured loan facility (the "Loan Facility"), which was previously announced in a news release dated July 16, 2013. The proceeds from the Loan Facility have been applied to the closing of the Transaction. Under the Loan Facility, Goldgroup will pay 15% interest annually, with nine equal principal and interest repayment installments, commencing April 30, 2014 and ending December 31, 2014. The Loan Facility can be repaid at any time without prepayment penalty. The Loan Facility is secured by a first priority lien on all assets of the Company.

Keith Piggott, Chairman, President, CEO and Director commented: "We are excited about the developments to date at the Cerro Prieto gold project. As we begin slowly winding down mining operations at Cerro Colorado, we are successfully transitioning equipment and personnel from there to the Cerro Prieto project. Furthermore, with the project finance in place, we are able to move the Cerro Prieto project closer to gold production which we anticipate over the next twelve months."
