Mammoth Energy Group Inc. (MMTE: OTC PINK) today announced that it has signed an initial option agreement to acquire up to 250,000 shares of the privately held Grand River Ironsands. Grand River Ironsands is the majority equity holder of The North Atlantic Iron Corporation.

The North Atlantic Iron Corporation (NAIC) is a joint venture between Grand River Ironsands Partners (GRI) and Petmin Limited of South Africa to develop the mineral sands in the 450 square kilometer site near Happy Valley Goose Bay, Newfoundland. The North Atlantic Iron Corporation is an iron sands to pig iron project with a maiden resource statement indicating an abundant low-cost feedstock for production of a concentrate for conversion into high-purity pig iron.

Petmin has an option on up to 49.9% of NAIC. It has joint management control and its stake in NAIC was 25% at November 2013, following a total investment of $13 million to date. Petmin’s earn-in option is for 40% of NAIC for $25 million with an option on an additional 9.9% at a market-related price.

The project has financial and political support from the Canadian government. The Atlantic Canada Opportunities Agency (ACAO) has invested $500,000 to partly finance the concentrator pilot plant through a repayable loan from ACOA’s Business Development Program.

NAIC produced its first concentrate in August 2012 following the processing of 8,000 tonnes of iron sands through a pilot plant. A continuous smelt test of more than 2000 tonnes of pig iron with Fe content greater than 55% is scheduled for completion in Q2 2013.

The NAIC resource is 594 million tonnes of sand grading at 9.35% heavy minerals, of which 38.02% is Fe2O3 equivalent. The maiden resource statement was based on just 3% of the NAIC claim and to a depth of 15 metres. Deeper drilling by Boart Longyear provides good indications that the resource extends well below 15 metres.

Privately held Grand River Ironsands Partners is currently the majority partner on the NAIC project. Grand River Ironsands Partners largest shareholder is publicly traded Muskrat Minerals, whose management controls both companies.

"This is our first step of many in a new direction,” said William Lieberman, President of Mammoth Energy Group. “It has taken a long time to finally be able to move the company forward, and Mammoth will be continuing to look to invest in larger North American projects that are in or close to production. In the upcoming weeks we will be announcing further developments as we seek to build a transparent, cash flowing company that will build value over time. We expect to close out this first initial option agreement in a very short time frame and have commitments already lined up for this acquisition. This project has been in development for more than ten years and I have followed it closely for a long time. There is a ton of material available on the project and I would encourage shareholders to look to see the depth, financial commitments, and the level of expertise that has moved this project forward in Canada. This is a long term investment with a significant valuation.”

Grand River Ironsands Incorporated (GRI) is a privately owned company focused on the ironsands of Labrador first discovered in 1896. Our corporate goals have been focused on what must be done with the iron sands to create economic success and to do so in an environmental leadership perspective. After three years of extensive research, collaboration and assessment – the Company is firmly of the view that it can produce a low cost iron ore concentrate that can be advanced to a high purity iron product. Moving from a model of simply mining heavy mineral sands to making a high purity iron (cast iron, iron ingots, pig iron) has added a valuable dimension.
