Merc Agrees to Acquire Colomac Gold Mine Consolidating Indin Lake Gold Camp

TORONTO, Dec. 15, 2011 /CNW/ – Merc International Minerals Inc. (“Merc“) (TSX Venture: MRK) is pleased to announce it has entered into an agreement to acquire the mineral claims and leases of the former producing Colomac Gold Mine (“Colomac“) in the Northwest Territories (“NWT“) from Aboriginal Affairs and Northern Development Canada (“AANDC“). Colomac represents a rare opportunity as a past producer and under-developed gold deposit with exploration potential. Merc believes there is an opportunity to develop resources at Colomac (as historic open pit mining was limited to less than 200 metre vertical depths and only one of five known deposits was developed). All deposits at Colomac remain open to depth and laterally.

Highlights:

David Wiley, Merc President and CEO, commented, “The acquisition of the former producing Colomac mine will represent a strategic milestone and completes Merc’s Indin Lake Gold Camp land package by adding a property that is entirely surrounded by our existing claims. We have obtained and analyzed historical data that indicates the potential for a substantial amount of gold to be present within the Colomac deposits. To that end, we have engaged ACA Howe, who visited the site in October 2011 and has been assisting in our due diligence, to complete a NI 43-101 technical report and mineral resource estimate on the property for early 2012. This next year will be a very exciting time for the company as we initiate a new and aggressive growth strategy focusing on increasing ounces at Colomac and advancing our satellite deposits towards a similar status.”

In consideration for the conveyance of the Colomac claims and leases, Merc will commit to reclaim three disturbed historic exploration sites near the Colomac mine within Merc’s surrounding Indin Lake land package. Reclamation will be carried out on behalf of AANDC to a maximum of $5,000,000. At closing, Merc will post security of $5,000,000 (the “Security“) in favour of AANDC to secure Merc’s obligation to perform the required reclamation. Merc will not be assuming the reclamation liabilities directly. The Security will be returned to Merc upon the completion of remediation activities to the satisfaction of an independent third party engineer. AANDC has substantially completed the reclamation of Colomac, with only adaptive management and monitoring phases of the project remaining. Merc is not responsible for any historical environmental liabilities associated with Colomac.

David Wiley continued, “This transaction benefits Merc shareholders by adding a bona fide past producing mine to our asset portfolio, while also allowing AANDC to realize their objectives of expediting historic remediation obligations, providing economic development, and creating job opportunities for the local First Nations communities.”

Closing of the transaction is expected to occur in late January 2012.  Merc has entered into negotiations with third parties for a $5,000,000 loan, which Merc intends to use to post the Security required to serve its obligations under the agreement with AANDC.

About Colomac

The Colomac mine is located 220 kilometres northwest of Yellowknife, NWT, within the central portion of the Indin Lake greenstone belt. Access is by winter road from Yellowknife for approximately three months each year or year round by chartered aircraft to a 5,000 foot airstrip at the Colomac mine site. Merc’s Indin Lake claims and leases (Figure 1) surround the property on all sides forming a contiguous land package. Five separate gold deposits makeup the Colomac property: Colomac Main, Grizzly Bear, Goldcrest, Dyke Lake, and 24/27. With the addition of Colomac, Merc has consolidated over 20 continuous kilometres of mineralized structure (Figure 2) that hosts 9 gold deposits (5 at Colomac, North Inca, Diversified, Lexindin, and # 3). To the north the mineralized structure deviates sharply to the west and hosts several gold showings over an additional 18 kilometres.

History

Gold was initially discovered at Colomac in 1945. In 1990, Neptune Resources Corp. (“Neptune“) put the property into production, but shut down in 1991 due to unfavourable gold prices after producing approximately 139,000 ounces. Royal Oak Mines Inc. (“Royal Oak“) acquired Colomac from Neptune in April 1993. Royal Oak recommenced stripping operations in March 1994, with first gold production in July 1994. Royal Oak closed the mine in December 1997 citing low gold prices and subsequently filed for court protection from its creditors under the Companies’ Creditors Arrangement Act in April 1999 in April 1999. AANDC became the owner of Colomac by way of Court Order dated December 13, 1999 following the receivership of Royal Oak and its related companies and proceeded to complete the required remediation for the site. All mining and milling facilities were removed from the site subsequent to AANDC taking control of the property.

During its peak, Royal Oak employed over 250 workers on the Colomac site. Production statistics are presented in Table 1.

General Geology

Colomac’s five known gold deposits lie within a north striking, steeply dipping, Archean greenstone belt of deformed sedimentary and intermediate to ultramafic volcanic rocks. Deposits appear in two distinct geological settings with the Colomac Main, Goldcrest, and Dyke Lake deposits hosted within quartz-feldspar porphyry dykes, whereas the Grizzly Bear and 24/27 deposits occur near or within the sedimentary/volcanic rock contact.

Colomac Main Deposit

All historic gold production has been extracted from the Colomac Main Deposit, which occurs in a north-south striking, quartz-feldspar porphyry dike approximately 6 kilometres long and 50 metres wide bounded by diorite and andesite. Mineralization is predominantly free gold spatially associated with quartz-carbonate veining and minor sulphides. During deformation, the dyke behaved as a competent unit enclosed within more ductile rocks, thus representing the classic competency contrast condition present in many Archean lode gold camps. This has led to the preferential emplacement of gold-bearing veins within the quartz-feldspar dyke.
