Integra Gold Closes Acquisition of Sigma-Lamaque Milling Facility and Mine and Subsequently Closes Waste Rock Purchase Agreement

VANCOUVER, BC--(Marketwired - October 09, 2014) - Integra Gold Corp. (TSX VENTURE: ICG) (ICGQF) ("Integra" or the "Company") is pleased to announce it has completed the required conditions and closed the acquisition of the Sigma-Lamaque Milling Facility and Mines (the "Property"), adjacent to Integra's Lamaque South Project in Val-d'Or, Québec (the "Transaction"). The 2,200 tonnes per day ("tpd") milling complex included as part of the Property is 500 meters and 2 km, respectively, from Integra's high-grade Parallel and Triangle Zones.

The Property was owned by Century Mining Corporation ("Century"), and Samson Bélair / Deloitte & Touche Inc. was appointed receiver (the "Receiver") to the assets of Century pursuant to a receivership order of the Québec Superior Court (the "Court") dated May 29, 2012. The Property was acquired from the Receiver, acting in such capacity. The aggregate purchase price is approximately $8 million, comprised of approximately $1.8 million in cash and 25 million common shares valued at $6.25 million. Integra paid $500,000 of the cash consideration to a third party for the crusher and related assets located on the Property.

The assets to be acquired by Integra include a permitted 2,200 tpd milling complex and tailings facility adjacent to Lamaque South, as well as permitted underground infrastructure including three portals, mechanical shop, office, dry, equipment, and all mining concessions and mineral claims on the past-producing Property.

Concurrent with the Transaction the Company also announces the closing of a separate agreement with a third party construction materials and mining service company (the "Waste Rock Company"), in which the Waste Rock Company has paid Integra $1,025,000 in cash in exchange for access and ownership over the waste rock on the Property as well as a portion of certain mining concessions. The Waste Rock Company will also assume all of the environmental reclamation obligations associated with their waste rock property, significantly reducing the overall obligation to Integra.

"Current market conditions have created excellent opportunities for well positioned companies such as Integra, and our acquisition of the Sigma Mine Complex adjacent to our existing resource base, is a fine example of this. The Lamaque South Project has the advantage of being located in close proximity to substantial key mining infrastructure, via our newly acquired Sigma Mine Project, all situated in one of the top mining jurisdictions in the world," commented Company President and CEO, Stephen de Jong. "The PEA study completed on the project in April 2014 is now being updated to reflect the impact of these infrastructural advantages on operating costs, capital costs, gold recoveries and the overall timeline forecasted to gold production. We anticipate disclosing the results of this study in the next four to six weeks."

Additional Details of the Transaction

The Integra Shares issued pursuant to the Transaction were issued at effective deemed price per share of $0.25, and will be subject to a four month hold period expiring February 8, 2015. The Integra Shares are also subject to a lock-up agreement covering an 18 month period, to be released as to one-third of the Integra Shares every six months being April 8, 2015, October 8, 2015 and April 8, 2016. Further details regarding the lock-up agreement are set forth in the news release of the Company dated September 3, 2014. The Receiver now holds an approximate 11.87% interest in the Company.

Transaction Highlights

• Attractive Purchase Price: Total acquisition cost of approximately $8 million, of which only $1.8 million is cash. Integra intends to use the $1,025,000 payable to it by the Waste Rock Company to pay for part of the cash consideration, resulting in a net cash outlay by Integra of $775,000.

• Substantial Asset Value: Purchase price represents a significant discount to the replacement value of the milling and tailings infrastructure, estimated in 2014 by WSP Canada Inc. ("WSP"), an independent engineering firm, at approximately $100 million exclusive of gold resources on the Property.

• Minimal Share Dilution and No Debt Burden: Secures future milling requirements for Lamaque South with limited share dilution and the assets will be vested in Integra free and clear of any claims, liabilities and encumbrances as a result of the Court order approving this Transaction. Integra also did not incur any debt to finance the Transaction. Integra Shares issued as consideration are subject to a staged lock-up period of 18 months and certain sales restrictions, as further discussed below.

• Reclamation Costs Mitigated through Waste Rock Agreement: An independent third party environmental and engineering firm was retained by Integra to evaluate future environmental reclamation obligations at the Property. The evaluation concluded $12.1 million will be required to complete full restoration work on the Property. After adjusting for the Waste Rock Company's removal of the waste rock and based on each parties' area of interest, Integra estimates its future reclamation obligations will be approximately $5.0 million on the Property. In addition, there is a pre-existing $3.5 million bond held in place with the Québec Ministry of Energy and Natural Resources ("MERN" or the "Ministry"). Integra and the Waste Rock Company have agreed, subject to the MERN's approval, to split this bond with $2.5 million going towards Integra's future environmental reclamation needs and the balance to the Waste Rock Company. Accordingly, Integra estimates that the net environmental reclamation obligation payable in the future by Integra on the Property will be approximately $2.5 million.

• Sigma Milling Facility Adjacent to Flagship Project: The milling facility is located less than 500 meters from the boundary of Integra's Lamaque South project. The mill is in excellent condition and has been well maintained throughout its care and maintenance period since May 2012. Operating capacity is in the range of 1,200 to 2,200 tpd.

• Potential Integration of Underground Infrastructure: Pre-existing, permitted and fully serviced portals and underground workings are in close proximity to the Parallel Zone at Lamaque South which could potentially be used to access mineralized zones. This development scenario could significantly reduce required underground development costs and the development timeline as a ramp from surface at the Parallel Zone would no longer be required. A drift from the existing underground working would reach the center of the Parallel Zone at an estimated vertical depth of 125 meters. Such access would enable a faster production ramp-up compared to the Preliminary Economic Assessment ("PEA") published on April 29, 2014.

• Project Synergies: The acquisition of the Property could reduce estimated capital and operating costs while also de-risking Lamaque South by, among others, securing processing capacity as opposed to the toll milling arrangements previously contemplated in the PEA. The original PEA estimated $46 per tonne in processing costs under a toll milling scenario, including transportation. Of that amount, the mark-up attributable to toll milling and the cost of transportation amounted to an aggregate of approximately $15 to $20 per tonne, which will now no longer be applicable. As a result, Integra expects production operating costs could be substantially less than that currently estimated in the PEA, which averaged 490,000 tonnes per annum for the life of mine. Additional surface infrastructure acquired through this Transaction, such as the mechanical shop, offices, dry and water management system, could further impact the capital expenditure estimates presented in the PEA.

• Tailings Infrastructure: The tailings facility on the Property currently has a two to three year capacity with ample room for future expansion requiring limited capital expenditure and permitting.

• Permits in Place: The mill and tailings facility are permitted for future use which will shorten the development timeline of the Property.

• Minimal Carrying Costs: Direct care and maintenance cost of the mill, including increased staff at Integra and ongoing dewatering of the existing underground infrastructure, are anticipated to be between $120,000 and $140,000 per month.

• Mineral Resource Complementary to Mill Acquisition: The Property contains 586,000 oz of Measured and Indicated gold resources at an average grade of 4.96 g/t and 1,853,000 oz of Inferred gold resources at an average grade of 6.29 g/t.

• Consolidates Land Position and Adds Exploration Targets: The acquisition adds 1,472 hectares of mining concession and claims adjacent to Integra's existing 1,509 hectare land position at Lamaque South. The sale also includes the transfer to Integra, subject to conditions of the past producing Sigma II Mine, located 25 kilometers east of Val-d'Or, consisting of 410 hectares of mineral claims. Including this land, Integra's total consolidated land position in Val-d'Or will amount to 3,391 hectares.

• Government Support: Integra has consulted closely with the MERN as part of its due diligence investigations. The detailed environmental reclamation plan prepared for Integra has been presented to the MERN. The MERN has indicated its support of the Transaction and the proposed division of the waste rock claims, and will be working with Integra as a revised reclamation plan is presented and implemented, although acceptance of such a plan will not be given by the MERN until an updated mine plan has been submitted.

• Positive Impact on Local Community: Creates additional jobs for the residents of Val-d'Or through the waste rock production by the Waste Rock Company over an estimated 20 year period. In addition, ancillary benefits from processing the waste rock include revitalizing the surrounding environment to its natural form and overseeing the restoration of a long-standing unaddressed historic mining site.

Waste Rock Agreement Summary

Integra and the Waste Rock Company have entered into an agreement whereby the Waste Rock Company is granted exclusive rights to waste rock on a portion of the mining concessions at the Property. The Waste Rock Company will assume all applicable reclamation and other environmental obligations in respect of their portion of the Property. Integra has granted to the Waste Rock Company preferential rights to waste rock on the rest of the Property and to waste rock on the adjacent Lamaque South Project. The Waste Rock Company has agreed to pay Integra $1,025,000 and has granted Integra preferential right to minerals contained on their portion of the Property.

Property Overview

The Property is comprised of the former Sigma (Placer Dome) and Lamaque (Teck Cominco) underground mines. Each of these two mines have, over 60 years of operating history, collectively produced over 9 million ounces of gold. The Sigma and Lamaque mines were consolidated under Placer Dome in 1993. Following Placer Dome's ownership there have been various owners with the most recent being Century since 2004. The Property has been on a care and maintenance program since 2012.

The Property is adjacent and directly north of Lamaque South. The mill has been well maintained and on an extensive care and maintenance program since its closing in May 2012. The mill has an operating capacity of 1,200 to 2,200 tpd with processing flowsheet using gravity concentration, cyanidation and carbon in pulp gold recovery, the process recognized as optimal for processing Lamaque South mineralization. Metallurgical gold recoveries from the mill have consistently been reported by prior operators in excess of 95% processing the same type of mineralization as that encountered at Lamaque South.

The Property has many key permits in place. Integra commissioned Golder Associates Ltd. ("Golder") to provide a study on the current condition of the tailings facility as well as future expansion potential. The tailings pond currently has two to three years of capacity which can be increased to accommodate future capacity requirements by raising existing dykes. This raise can be completed by utilizing tailings and waste material already on site. The tailings facility has been maintained and monitored by a full time environmental manager throughout the care and maintenance period and is considered to be in good standing with the MERN. The tailings are non-acid generating.
