Minto fits perfectly with the Company's stated goal to acquire a producing and profitable mining operation to which our team can add further value. This acquisition will represent a core asset to Pembridge and will be used as a platform for future growth.

We believe Minto is an exceptional opportunity with the potential to benefit not only our shareholders but also the local and wider community for many years to come. We look forward to engaging with and working closely alongside the Selkirk First Nation, the various local communities, the Yukon Government and the substantial workforce at the mine.

Pembridge is guided by its board, management and technical team, who have a range of experience in mining operations and finance. In addition, two of our board members have prior connections to the Minto mine. Their experience, complemented by the rest of the team, will be instrumental in seeking out efficiencies and delineating the surrounding area's potential.'

Minto mine overview

Minto is an open pit and underground copper-gold-silver mine located in central Yukon, approximately 240 kilometres north of the capital Whitehorse along the Klondike Highway. The Minto mine has been in continuous production since 2007 and is presently the only operating mine in Yukon territory. In excess of US$350 million of capital expenditure has been invested into Minto since site construction began some 12 years ago.

Minto started as an open pit mining operation utilising conventional truck and shovel mining. Concurrent underground operations commenced in 2014 using a combination of room and pillar and long-hole stoping retreat mining methods. Ore is transported to a processing plant with a capacity of 4,000 tonnes per day, which produces a high quality concentrate averaging 35-40% contained copper.

In 2017, Minto produced 16,332 tonnes of copper, 170,809 ounces of silver and 25,205 ounces of gold. Production guidance from Capstone for 2018 is 19,000 tonnes of copper. C1 cash costs are forecast by Capstone to be US$2.35 to US$2.45 per pound with all-in sustaining costs of US$2.55 to US$2.65 per pound.

Pembridge management has identified a number of potential operating efficiencies that it believes could significantly lower operating costs.

Currently, all silver ounces and up to 30,000 ounces of gold production per annum is subject to a precious metal purchase agreement with Wheaton Precious Metals Corp.

The existing Minto mine plan, prepared by Capstone, contemplates the continuation of operations through to mid-2021. This is based on the mining of certain of the open-pit and underground deposits comprising a portion of the existing resource base. Between 2008 and 2012, Capstone invested approximately US$24 million in exploration and added over 500,000 tonnes of contained copper resource. No exploration activities have been undertaken on the property since. However, a number of prospective exploration targets have been identified and will require drilling.

Immediately following the completion of the Proposed Acquisition, Pembridge management will implement a number of strategies to seek to significantly extend the current four year mine plan.

Mineral Reserves and Mineral Resources for Minto are prepared in accordance with Canada's National Instrument 43-101 - Standards of Disclosure for Mineral Projectsand have, in the past, been annually stated by Capstone. A Mineral Reserve and Mineral Resource Report to the financial year ended 2017 will be prepared by the Company in conjunction with Capstone (the 'Competent Persons Report') and will be included in a prospectus (the 'Prospectus') to be filed by the Company in accordance with the Listing Rules and Prospectus Rules of the FCA.

Transaction

Under the terms of the SPA, Pembridge will acquire a 100% interest in Minto through the acquisition of Capstone's 100% interest in Minto Explorations Ltd. The purchase price for the Minto mine will be comprised of a cash consideration of US$37.5 million and the issuance of Consideration Shares such that Capstone will own 9.9% of the issued share capital of Pembridge as enlarged by the Proposed Acquisition. The Proposed Acquisition is structured on the basis that Minto is being acquired on a debt free, cash free basis with normalised working capital.

The Proposed Acquisition constitutes a reverse takeover for the purposes of the Listing Rules of the FCA, and accordingly the Company requested that the FCA suspend the listing of Pembridge's Ordinary Shares with immediate effect. The Company will proceed to prepare and publish a Prospectus in the coming weeks which will include the Competent Persons Report on the assets of the Company as enlarged by the Proposed Acquisition.

The Company and Capstone have entered into a lock-in and orderly market agreement (the 'Lock-in'). The Lock-in will provide that (i) Capstone will agree not to sell any of the Consideration Shares for a period of one year from the date of Admission and, (ii) Capstone will have the right to participate in future equity offerings in order to maintain its pro rata ownership.

Completion of the Proposed Acquisition is subject to customary closing conditions, including shareholder and regulatory approvals. Pembridge currently expects the Proposed Acquisition to close in April 2018.

Financing

In connection with the Proposed Acquisition, Pembridge will undertake a financing to raise approximately US$50,000,000 (the 'Financing'') to fund the acquisition price together and working and resource development capital. Pembridge is actively engaged with a number of potential capital providers and is currently reviewing available financing options. It is currently anticipated that the Financing will be funded through an equity placement (the 'Placing'). GMP Securities L.P. and Arden Partners plc have been engaged by the Company to act as brokers and bookrunners in connection with the Placing.
