Updated Preliminary Economic Assessment Highlights:

  • Average annual gold production for first full 8 years estimated at 135,000 ounces, average annual gold production for Life of Mine (“LOM”) estimated at 123,000 ounces, and total production of 1.3 M ounces, a 156% increase from the 2015 PEA

  • LOM cash cost of C$595/oz (US$458), all in sustaining cost (“AISC”) of C$824/oz (US$634) and fully loaded cost (AISC + initial capital expenditures) of C$933/oz (US$718)

  • Pre-production period of 18 months with pre-production capital (“Initial Capital”) requirement net of pre-production revenue of C$111 M (US$85 M) – Initial Capital excluding pre-production revenue of C$175 M (US$134 M)

VANCOUVER, BC: Integra Gold Corp. (TSX-V: ICG; OTCQX: ICGQF), (“Integra” or the “Company”) is pleased to announce the results from an updated Preliminary Economic Assessment (“PEA”) which includes resources from the Company’s Fall 2016 Resource Estimate (see news release dated November 16, 2016) for the Lamaque South Gold Project (“Lamaque”) in Val-d’Or, Québec. The PEA has been prepared in accordance with National Instrument 43-101 of the Canadian Securities Administrators (“NI 43-101”). The 2017 PEA incorporates many resource base, extraction design and mine plan improvements over the 2015 PEA and the updated financial projections indicate that Lamaque is a robust project at current gold prices. An underground exploration ramp to support a bulk-sampling program in Q3 2017 is currently underway at Lamaque with 658 meters (“m”) (1,049 m total) of development completed on the main ramp as of February 16, 2017.

The 2017 PEA was prepared by InnovExplo Inc. (“InnovExplo”). The study was conducted under the direction of Mr. Langis St-Pierre, P. Eng., Integra’s Chief Operating Officer, and Mr. Francois Chabot, P. Eng., Operations Manager, along with the Company’s entire operations team based in Val-d’Or, Québec. The study also included contributions from the geological and engineering teams at Geologica, GéoPointCom, Amec Foster Wheeler, and WSP Canada Inc.

A NI 43-101 Technical Report that summarizes the results of the PEA will be filed on Integra’s SEDAR profile at www.sedar.com within 45 days.

Economic & Operational Highlights:

The PEA is considered preliminary in nature. It includes inferred mineral resources that are considered too speculative to have the economic considerations applied that would enable classification as mineral reserves. There is no certainty that the conclusions within the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

  • Pre-production period is 1.5 years and mine life has more than doubled from 4.5 years to 10.5 years as a result of substantial resource growth since 2015.

  • Average annual gold production of 123,000 ounces, including 135,000 ounces for the first full 8 years, and peak production of 155,000 ounces reached in year 7.

  • As a result of significant infill drilling and the 2015 identification of the “C structures” at the Triangle Deposit (“Triangle”) following the previous PEA, long-hole mining will now account for 71% of mined material at Triangle (90% when not including material mined through development), reducing total mining costs to C$86/tonne which includes the reduction of direct stope mining costs (stope mining, mucking, hauling, supervision, equipment maintenance) from C$78.50/tonne (PEA 2015) to C$39.80/tonne.

  • At its peak, the Lamaque Project will employ up to 425 people, and will thus be a significant driver of the local economy in Val-d’Or, Québec.

Integra President and CEO, Stephen de Jong, commented, “First and foremost I want to thank our exploration and engineering teams who have worked diligently and collaboratively to produce the PEA. They deserve full credit for the incredible job they have done in continuing to grow the project’s resource while methodically exploiting every opportunity to increase the scope and scale of the project. They have also been disciplined in our allocation of capital which has protected the underlying project margins. With only a marginal increase in total capital compared to the 2015 PEA, the project is now able to demonstrate substantially higher economic returns, a much longer mine life, more than double the amount of recovered ounces, and a material increase in the annual production profile while still managing to operate with all-in sustaining costs of less than US$650 per ounce.”

Mr. de Jong adds, “With an industry leading total capital to NPV ratio, this study further demonstrates Lamaque’s extremely rare positioning as a project in a safe jurisdiction with high grades and high margins, with the potential to be up and running in less than two years. The study also outlines several opportunities to further enhance project economics which we will continue to assess as we move closer to the completion of a bulk sample, which we are aiming to complete in Q3. In Q1, we also look forward to an updated resource estimate for Triangle that will incorporate 105,000 m of new drilling not included in this study.”

Project Economics

Assuming a gold price of US$1,250 per ounce, an exchange rate of C$1.30 to US$1.00, and a discount rate of 5% adopted by the Qualified Persons (“QPs”), Lamaque’s estimated pre-tax NPV is C$601.9 M and pre-tax IRR is 55%. The after-tax NPV is C$362.5M and after-tax IRR is 43%. Payback from the start of construction on Lamaque is 3.8 years pre-tax and 4.2 years after tax. Project economics are sensitive to metal prices and exchange rate assumptions as seen in the sensitivity analysis below.

Cautionary Statement

The projected mining method, potential production profile and mine plan are conceptual in nature and additional technical studies will need to be completed in order to fully assess their viability. There is no certainty that a potential mine will be realized or that a production decision will be made. A mine production decision that is made without a feasibility study carries additional potential risks which include, but are not limited to, the inclusion of inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. Mine design and mining schedules, metallurgical flow sheets and process plant designs may require additional detailed work and economic analysis and internal studies to ensure satisfactory operational conditions and decisions regarding future targeted production.

Project Enhancement Opportunities

  • Resource Expansion:
    • Updated resource estimate for Triangle now underway (expected in Q1 2017) which will include an additional 105,000 m of drilling completed in 2016 which was not included in the resource estimate used for the base of the PEA.
    • Other deposits, including the historic Sigma Deposit, are under review and may be included in future economic studies.

  • Reduction of Pre-Production Capital Expenditures:
    • Potential to utilize contract mining in order to reduce pre-production capital requirements.
    • Postpone Parallel Deposit (“Parallel”) development thereby deferring associated pre-production requirements.

  • Mine Plan Optimization:
    • Integrate updated Triangle resource estimate into a revised mining plan to reduce capital requirements and improve pre-production scenario with a view to optimize capital requirements and to control/minimize dilution and optimize mineral recoveries, including the evaluation of alternative mining methods to lower the proportion of room-and-pillar stope mining.

  • Metallurgy/Milling:
    • Potential for further improvement in gold recoveries based on new metallurgical test work.
    • Leach tests with pre-aeration conducted on Triangle resulted in a considerable reduction in cyanide consumption. Pre-aeration has the potential to reduce reagent consumptions for Parallel and the No. 4 Plug Deposit (“No. 4 Plug”) as well, for which no tests with pre-aeration have been conducted yet.

Recommendations and Next Steps:

  1. Q1 – 2017: Incorporate all new drilling into a global project resource estimate
    1. Updated Triangle resource estimate for Triangle incorporating 105,000 m of new drilling completed in 2016 nearing completion (note: none of the 2017 drilling completed at Triangle or other targets will be included in the updated resource estimate. See 2017 Press Releases for information on those results).

  1. Q3 – 2017: Complete underground exploration and bulk sample program at Triangle
    1. Development work completed as part of the underground exploration program will provide critical information on Triangle.
    2. Upon completion both the capital requirements and the length of the 18 month pre-production period will be materially reduced.

  1. Ongoing: Continue exploration and definition drilling at Lamaque

  1. Ongoing: Continue information/consultation meetings and finalize permitting initiatives to support pre-production and production objectives

Annual Production Profile

The production profile for Lamaque has increased 156% from 511,600 ounces total in the 2015 PEA to 1,311,264 ounces total. Average annual LOM gold production is 123,000 ounces, including 135,000 ounces for the first full 8 years, and peak production of 155,000 ounces reached in year 7.

Note: Initial Capital includes a 20% contingency (10% contingency for mobile equipment).

Development costs, which represents ~27% of the pre-production capital, have been estimated based on actual development costs from Promec Mining (“Promec”), who is currently conducting work on the Triangle exploration ramp. For the first year of development on Triangle and Parallel, development unit cost estimates from Promec were used which included supervision. For subsequent years, unit costs for variable size development scenarios (ramping, sub-level development) were used, based on planned performance rates, expected wages and bonuses to be paid to Integra’s development team. Development costs also include maintenance costs for equipment based on estimates provided by suppliers for similar mining operations.

Mobile equipment cost estimates are based on actual Integra rented equipment charges and quotes obtained directly from major equipment suppliers.

The majority of the Sigma mill refurbishment work will commence in the first quarter of year two and will be completed at the end of the second quarter in year two. WSP Canada Inc. (“WSP”) has completed a detailed capital cost evaluation of the required work for mill refurbishment taking into account its current state and requirements prior to being fully operational. Pre-production is estimated to be C$12.7M.

Current surface electrical installation will be enlarged to add transformers to supply underground equipment at 13,800V. Initial and sustaining capital for underground electrical installation has been evaluated in line with requirements for ventilation, pumping, development and production mobile equipment.

Ventilation equipment and an air heating system will be installed progressively. The maximum requirement for ventilation at Triangle/No. 4 Plug is 600,000 cfm and 245,000 cfm for Parallel. Total ventilation initial and sustaining capital are C$10.9M.

At Triangle, enlargement of existing surface garage is planned in year 1 and construction of a building to host a 300 person dry and office for supervision, technical and administration personnel is planned in year 3. A surface mixing plant is planned for cemented rockfill at Triangle and Parallel. Total initial and sustaining capital are C$16.8M for the buildings.

Operating Costs

LOM cash cost is expected to average C$595 per ounce and the AISC is expected to average C$824 per ounce.

Mining

Underground mining at Lamaque will consist of long-hole and room-and-pillar mining methods. The incorporation of steeply dipping C structures at Triangle in this PEA has resulted in greater utilization of the long-hole mining method, a more cost effective, efficient and safer mining method. For production of mineralised material coming from stopes, long-hole mining represents 90% of the tonnage and room-and-pillar 10%. Globally (including development), long-hole mining accounts for 71% of the tonnage produced at Triangle and 69% at Lamaque. The increased use of long-hole mining has reduced the stope mining cost per tonne, increasing the mining rate at both Triangle and the No. 4 Plug and improving overall economics and scale of the project.

Stope development includes various horizontal access to mineralised material and development directly in mineralized material. Mine planning and scheduling was done to give numerous access to major zones (C2 and C4 at Triangle) and generate as many as 10 production centers of long-hole stopes at Triangle and the No. 4 Plug. Development in mineralised material generates about 23% of all the tonnage produced.

Rock mass characterization was done by Golder Associates in 2014 and was revised for Triangle using diamond drill core from 2015 and 2016. The rock mass classification was used to define long-hole stope size, cable bolting required and dilution. Simulations were completed for the long-hole stopes to define the best mining sequence. The rock mass classification was also used to design basic rock support for various development. Crown pillar sizing was done by Golder Associates in 2014.

An average dilution of 35% (at 0.0 g/t Au) has been applied for stope true thickness of 2 m. The dilution is adjusted progressively to a minimum of 20% when stope true thickness is equal or greater than 4 m. For Triangle, the long-hole stope thickness prior to dilution ranges between 2 m and 10 m for an average thickness of approximately 4 m. At No. 4 Plug, long-hole stope thickness prior to dilution ranges between 2 m and 3.2 m and for Parallel, long-hole stope thickness prior to dilution ranges between 2 m and 4 m.

Mucking will be done longitudinally using remote controlled LHD equipment with mining recovery estimated to be 85% (pillars and material left in stope).

For mineralized zones dipping less than 40 degrees, the room-and-pillar mining method will be utilized. Mechanized sub-level development in mineralized zones will be completed at 60 m intervals along the veins. Rooms will be approximately 6 m in width and a performance rate of 18 tonnes/shift was used in the mine plan. Typical stopes will have a height of 2 m and external dilution of 5% (at 0.0 g/t Au). Mining recovery is estimated at 85% (pillars and material left in stope).

Processing

The Sigma Mill is 100% owned by the Company and was fully operational as recently as 2012. The mill is located approximately 3.0 km from Triangle and 1.0 km from Parallel. Since 2014, the Company has had four full time mill employees who continue to conduct ongoing refurbishment and maintenance work in order to prepare for future operations.

During the pre-production period, offsite toll milling is planned as tonnage is insufficient to justify starting the Sigma Mill. Transportation (C$4.15/tonne) and milling (C$41-C$43/tonne) quotes from the specific mills identified were used in the cash flow model as well as the expected gold recoveries (89% Triangle and 94.7% Parallel). Transition from toll milling to processing at the Sigma Mill is expected to take place in Q3 of year 2 in the proposed mine plan, at the end of the 18 month pre-production period.

During the production phase, average mill throughput rate is expected to be approximately 1,675 tonnes per day based on 350 operation days/year. This includes resource extraction from both Triangle and Parallel from year 2 to 5, Triangle only for years 6 and 7, and both Triangle and the No. 4 Plug in years 8 to 11. The No. 4 Plug is the sole source of mineralised material in year 12.

During the production period, average milling cost of C$23 per tonne ($25 including transportation) was estimated by WSP. The milling cost includes a work force of 33 employees or 23% of the cost, reagents and consumables for 39%, maintenance for 20% and energy for 12%.

Tailings

Amec Foster Wheeler (“Amec”) developed a long term strategy, including construction and deposition plan, to manage tailings and water based on the proposed 10.5 year production period.

The Sigma tailings impoundment area is made up of four separate cells. A recirculation pond and a polishing pond are located to the east of those four cells. Currently, two cells out of four cells are full. To lower water levels in tailings pond during deposition, 2 new water ponds will be built east of the tailing ponds. These new ponds will facilitate water management during tailings disposal and for strong precipitation. The existing polishing pond will serve to manage dewatering water from underground operation.

Using actual quotes, an evaluation prepared by Amec estimates initial capital requirements associated with the tailings to be C$2.5 M and sustaining capital at C$10.2 M. The estimation costs include a 30% contingency.

To date, the tailings facilities have been maintained with a full time environmental technician providing monitoring. Amec is also conducting an annual geotechnical inspection of the tailings and water pond. The tailings facilities are deemed to be in good standing with the Ministry of Energy and Natural Resources (“MENR”) and the tailings in place are not acid generating.

Metallurgy

Phase 4 metallurgical test work was completed in 2016 on material from Triangle. WSP supervised detailed metallurgical testing to improve gold recoveries on representative core samples from the various mineralized zones. Acid base accounting (“ABA”) testing done shows that material was not acid generating. Grindability testing was completed and Bond rod mill index (“RWI”) results are in a range of 16.7 to 17.3 kWh/tonne and Bond ball index (“BWI”) are from 15.5 to 16.4 kWh/tonne. The rock samples tested can be categorized as moderately hard.

Environmental, Permitting and Reclamation

No provincial environmental impact study is required at Lamaque as the provincial daily production threshold is 2,000 tonnes, higher than the proposed mine plan.

The Company currently has the provincial Certificates of Authorizations (“CA”) for the underground bulk sampling program underway at Triangle. Documentation for a CA which will cover initial production at Triangle is now being prepared along with a review of the approved closure plan for the Triangle site. Documentation for these two items will be submitted in Q2 2017 for approval.

The Company currently has a permit for a 5,000 tonne bulk sample and concurrent with the other CA applications underway, is preparing an application for an extension permit for up to 50,000 tonnes. In addition to this, the Company is preparing the required documentation for its application to convert the remaining Triangle exploration claims to mining leases as required by Québec Mining Law.

The existing CAs which cover the Sigma mine and associated mining leases allow underground production up to 2,500 tons per day at Parallel and No. 4 Plug to a depth of 400 m. When required, modifications to these CAs will be prepared to cover production from the lower portion of the No. 4 Plug. A review of the closure plan for the Sigma site is being prepared and will be submitted in Q2 2017.

Reclamation costs for the Sigma site, including the mill and tailings facilities, have been evaluated at C$7.8M. Reclamation costs for the Triangle ramp were estimated to be C$1.3M. It should be noted that the financial guarantee in place for the project is currently C$3.2M and that amount will be updated following acceptance of the new reclamation plans which will be submitted to the Québec Natural Resources Department in 2017.

Community Relations

Since September 2013, the Company has initiated a proactive information and consultation strategy with its stakeholders. With the help of consulting firms such as Amec, Transfert Environnement and TMR Communication, the Company has conducted four phases of information and public consultation with approximately 40 stakeholders reaching more than 600 persons.

From June 2014 to January 2015, a consultation committee was organized to discuss the community impact of the project with an independent moderator chairing each meeting. Site visits to Lamaque and Sigma site and other similar operations in Québec were organized to present accurate and relevant information about the project and the mining industry to the committee’s 20 members. For each potential impact identified, a specialist retained by the Company presented basic information on the topic, applicable regulations and outlined the impact generated by the project and the mitigating measures that are applicable. Integra has also taken various commitments to be fulfilled during project development. The consultation committee has evaluated that the impacts generated by Lamaque are acceptable.

In May 2015, a follow-up committee was formed to keep the Company’s stakeholders informed about Lamaque. Quarterly meetings are organized where committee members receive updates on the status of the project and all proceedings are on the Company’s website. From April to May 2016, three meetings were organized to present to the committee the revised impact of the project as the resource has grown substantially leading to various impacts on the Company’s plans. The follow-up committee members were pleased with the information received and agreed that the project remains socially acceptable.

A comprehensive complaint process has been in place since March 2016 which allows for citizen or organizations to register complaints in regards to Integra’s activities. No complaints have been received from the local population since this process was implemented.

Mineral Resource Estimate

The Company’s November 2016 resource estimate was used as the resource base for the PEA. An updated resource estimate is planned for Lamaque in Q1 2017 which will include approximately 105,000 m of new drilling from Triangle. Note, none of the drilling completed in 2017 will be used in this updated resource. The resource estimate used in the PEA is outlined in the table below at a 5 g/t Au cut-off. The cut-off grade used for the mine plan in the PEA varies depending on mining method and other factors.

Project and Company Profile

Integra Gold is a junior gold exploration company advancing projects in Val-d’Or, Québec, one of the top mining jurisdictions in the world. The Company’s primary focus is its high-grade Lamaque South project. In the fall of 2014, Integra completed the accretive acquisition of the Sigma Mill and Mine Complex, a fully permitted 2,200 ton per day mill and tailings facility. With major federal and provincial permits in place, existing infrastructure and significant exploration potential, this acquisition removed major costs and shortened timelines typically associated with mine projects. Integra has raised over $125 million since 2013, at successively higher share prices, despite depressed gold prices. In August 2015, Eldorado Gold Corporation completed a strategic investment in Integra, acquiring 15% of the outstanding common shares. Integra was named to the TSX Venture top 50 performers in 2015 and the OTCQX Best 50 award for 2015.
