The offering would be the first pure IPO on the TSX in over a year, as the pullback in metal prices has sharply dented investor confidence in the mining industry and led to a major slowdown in new mining listings on the resource-heavy TSX and TSX Venture Exchange.

TMAC, which has privately raised over C$157 million ($126 million) since it was formed in 2012, is largely owned by mining-focused private equity firm Resource Capital Funds (RCF) and gold miner Newmont Mining (>> Newmont Mining Corp), which sold the Hope Bay project in Nunavut to TMAC in 2013.

RCF owns a 39.5 percent stake, while Newmont controls a 37.8 percent stake.

TMAC is expected to file its paperwork around the offering, which is being led by BMO Capital Markets and CIBC, very soon, said the source, who asked not to be named.

BMO and CIBC declined to comment on the matter. TMAC was not immediately reachable for comment.

Earlier on Friday, The Wall Street Journal, citing sources familiar with the matter, reported that TMAC will look to raise over C$100 million through the IPO. It said the offering will be backed by a syndicate that also includes Dundee Capital Markets, Toronto-Dominion Bank, GMP Capital Inc, Scotiabank and National Bank Financial.

The Hope Bay project is one of the most advanced gold assets in Canada and was originally owned by mining giant BHP Billiton (>> BHP Billiton Limited) (>> BHP Billiton plc) before the turn of the century. Newmont went on to acquire the asset and spent over C$800 million on the project before mothballing it, due to debt woes and a slump in the price of gold.

TMAC has revived the project, altered the scope of the mine plan and aims to have the mine in production by late 2016.

The exploration company is led by a team of veteran mining hands from erstwhile Canadian base metal miner FNX, which went on to merge with Quadra Mining in 2010. The merged entity Quadra FNX was later acquired by Polish miner KGHM (>> KGHM Polska Miedz SA) for roughly C$3 billion in 2012.

TMAC completed a pre-feasibility study last month that laid out the costs and scope of the project. [http://bit.ly/1c1xpEE]
