INV METALS ANNOUNCES UPDATED POSITIVE FEASIBILITY STUDY FOR THE LOMA LARGA GOLD-COPPER-SILVER PROJECT

INV METALS ANNOUNCES UPDATED POSITIVE FEASIBILITY STUDY FOR THE LOMA LARGA GOLD-COPPER-SILVER PROJECT

TORONTO, March 31, 2020 (GLOBE NEWSWIRE) — INV Metals Inc. (“INV Metals” or the “Company”) is pleased to announce the positive results of the independent updated Feasibility Study (“FS”) prepared for its 100% owned Loma Larga gold-copper-silver project (“Loma Larga” or “Project”), located in Ecuador. Unless otherwise stated, all amounts are stated in U.S. dollars (“$”).Ms. Candace MacGibbon, CEO stated, “We are very pleased to release the positive results of the updated Feasibility Study which incorporate the relocation of the plant infrastructure and tailings facility near the proposed mine site; updated capital and operating cost estimates; and current Mineral Resources and Reserves. While the capital and operating costs have not changed materially since the results of the previous Feasibility Study were filed in January 2019 (“2019 FS”), the gold price environment has strengthened and we have reflected the current long-term consensus gold price of US$1,400/oz into the FS. The Project is forecasted to return a robust after-tax 28.3% Internal Rate of Return (“IRR”) and 2.4 year payback period. The FS reaffirms the Project’s viability, demonstrating the strong profitability and economics of the Loma Larga gold-copper-silver project.”Ms. MacGibbon continued, “Our focus in 2020 is to continue to advance the environmental permitting process with the goal of obtaining the required significant permits for development. The first milestone in the process is the completion and submission of the Environmental Impact Study (“EIS”) to the Ministry of Environment (“MAE”). We are working together with the MAE and the Ministry of Energy and Non-renewable Resources to achieve this goal.”Loma Larga is projected to be a low-cost operation with expected life of mine (“LOM”) cash costs of $559/oz, all-in sustaining costs of $627/oz, and all-in costs of $789/oz. Initial pre-production capital expenditures are estimated at $316 million, with sustaining capital of $71 million and closure costs of $22 million (including taxes and duties). The projected 12 year mine life and forecasted life-of-mine mined production remains unchanged. Average yearly mined production is forecasted at 223,000 gold equivalent ounces, with an average of 289,000 gold equivalent ounces mined during the first four full years.Ms. MacGibbon added, “Loma Larga is a relatively simple mining project which will incorporate environmental management initiatives that will provide for the stewardship of water, flora and fauna. We are committed to executing the development of Loma Larga in a socially responsible and environmentally sustainable manner. The underground mine and related processing infrastructure have been designed to have a very minimal footprint, with an estimated disturbance area of less than 65 hectares at the Project site. The process plant and tailings facility designs, including the use of paste backfill and a filtered tailings disposal method, along with the use of recycled water in the plant and controls for surface run-off, will serve to minimize the use of surface water and reduce the treated water discharge. Management expects to extract no more water from existing water sources during mining operations than was approved during the exploration phase.”She further added, “Loma Larga is one of five strategic mining projects identified by the Government of Ecuador and will be the next large-scale mining development project to be financed and permitted in the country, following upon the success of the Fruta del Norte gold project by Lundin Gold Corp. With the demonstrated strong support of the Ecuadorian government and our surrounding local communities, INV Metals plans to aggressively move the Project forward aiming to break ground in 2021 with the goal of achieving first gold concentrate production in late 2022. The positive social and economic impacts will be important both locally and nationally, and will provide exciting new employment, training, procurement and business opportunities throughout the region.”Feasibility Study Highlights (5% discount rate, $1,400/oz gold, $18/oz silver, $3/lb copper)The updated FS was prepared by a consortium of independent consultants, led by DRA Americas Inc. (“DRA”), an international engineering firm with extensive experience both in the construction and operation of mining projects.The FS is currently being summarized into a Technical Report (the “Loma Larga Technical Report”) to be filed on SEDAR in accordance with National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”).Table 1 – NPV and IRRThe FS after-tax NPV using a gold price of $1,250 per ounce is $356 million, with an IRR of 24.4%, and a 2.6 year payback period. This is comparable to the results of the 2019 FS using a gold price of $1,250 per ounce which returned results of an after-tax NPV or $356 million, an IRR of 24.7%, and a 2.6 year payback period. Table 3 below illustrates the sensitivity of the NPV and IRR to different gold price scenarios.Table 2 – Key Financial Metrics2The FS demonstrates that the development of Loma Larga is expected to provide substantial economic benefits to the future employees of INV Metals, our communities, and the local, provincial and federal governments of Ecuador. The development and operation of the Loma Larga mine will also provide numerous employment and business opportunities for the local communities and within the region. Various benefits are expected to include:continuation of the Company’s numerous social programs;during the construction period of 18-24 months, an estimated direct employment of 875 people;when the mine is in operation, an estimated 450 permanent direct jobs;economic development and the creation of indirect jobs with local procurement initiatives and training opportunities;wages, social security and pension benefits are estimated at $15 million annually, for a total of $186 million over the mine life;employee profit sharing taxes (3%) are estimated at $34 million;taxes to the Government of Ecuador are estimated at:Corporate Income tax (25%) – $226 millionState profit sharing tax (12%) – $135 millionEmployment taxes (35%) – $52 millionVAT (12%) and import duties (0% – 5%) – $109 millionRoyalties (5%) – $120 millionTable 3 – Gold Price Sensitivity3NEXT STEPSPermitting ProcessFor the remainder of 2020, INV Metals will focus on permitting efforts for Loma Larga, which are led by Dr. Mark Thorpe, who has over 25 years of experience in environmental, social, governance and permitting. With the completion of the updated FS, the Company will be primarily focused on obtaining the key environmental permits, along with an Investment Protection Agreement, to allow for the Board of Directors to make a development decision on Loma Larga. The permitting process will include the completion and submission of the EIS which will incorporate relevant technical information from the FS where appropriate, along with community consultation efforts and communication programs. The submission of the EIS is expected prior to the end of Q2/2020 but may be subject to delays as a result of current and/or any future restrictions which may be in place due to the COVID-19 global pandemic.Project FinancingThe Company will concurrently focus its efforts to secure funding for the development of Loma Larga. Management will explore a range of various financing options which may be available to the Company, including Project debt, by-product streams, off take arrangements and/or equity financing.ENVIRONMENTAL, SOCIAL AND GOVERNANCEThe Company is committed to maintain and build upon its strong Environmental, Social and Governance  (“ESG”) programs and to engage in meaningful consultation with our stakeholders. INV Metals is committed to developing the Loma Larga gold-silver-copper project in an environmentally sustainable manner and to executing using best-in-class standards within the global mining industry. The Loma Larga underground mine is an environmentally focused mine, supported by key technical benefits such as the use of tailings in paste backfill, a filtered tailings disposal method, the shipment of concentrates, and no cyanide to be used in the process plant.Water ManagementThe Company recognizes that the stewardship of water is a critical issue and concern among all stakeholders and therefore INV Metals has designed its water management practices using accepted best-in-class standards. All water that comes into contact with mined material will be treated prior to release. Natural runoff will be diverted around the mine infrastructure to the extent possible. Contact water, including water that must be withdrawn from the underground mine to maintain a safe working environment, will be collected and used for mineral processing. Excess contact water, not used in mineral processing, will be treated prior to discharge in the receiving environment. Water management, including water treatment, will continue during the closure phase until discharge from the site meets established discharge criteria without active treatment.Filtered Tailings Storage FacilityIncreased controls and monitoring of tailings facilities should be incorporated into the engineering design for all future mining projects and as a result, the design of the filtered tailings facility incorporates the current guidance from well known experts related to the technical stability of the design. The tailings storage facility will store filtered tailings within a lined and contained area to minimize the amount of impounded water, allow for the diversion of surface water, and the collection of contact water for treatment. Approximately 6.5 million tonnes of plant tailings are expected to be placed underground as paste backfill, with 5.5 million tonnes remaining on surface in the tailings storage facility which will be covered at closure with liners and rehabilitated with indigenous plants and grasses. The Company has a nursery on site which hosts, along with animals for educational purposes, over 50,000 indigenous trees and shrubs for planting during rehabilitation.Social Programs and ConsultationsThe Company has worked together with the local governments and community groups for over 15 years to deliver impactful programs that are generated in conjunction with the participants. The employees of INV Metals are dedicated to and passionate about our relationships with our local stakeholders. We look forward to the consultation process to welcome informed and transparent dialogue with our communities and other important stakeholders.FEASIBILITY STUDY DETAILSMineral ResourcesThe Loma Larga gold-silver-copper deposit is classified as a high sulphidation epithermal system and alteration is characterized by multiphase injections of hydrothermal fluids strongly controlled by both structure and stratigraphy. The deposit is a flat lying to gently western dipping (less than ten degrees), north-south striking, cigar shaped body, which has a strike length of approximately 1,600 metres north-south by 120 metres to 400 metres east-west and up to 60 metres thick, beginning approximately 120 metres below surface.RPA Inc. (“RPA”) estimated Mineral Resources for Loma Larga using all drill hole data available as of September 1, 2018. No further exploration drilling has occurred at Loma Larga since that date. The current Mineral Resource estimate is based on an underground mining scenario and is reported inclusive of Mineral Reserves. Using a US$55/t Net Smelter Return (“NSR”) cut-off value, Mineral Resources effective as of March 31, 2020 are summarized in the following table. The Mineral Resource estimate was updated using estimates of $1,650 per ounce of gold, $21 per ounce silver, and $3.75 per pound copper, an increase in price from the 2019 FS which used $1,450 per ounce gold and $3.50 per pound copper, and a decrease from $22 per ounce silver. The effect of the increase in gold prices was an increase in Measured and Indicated Resources from 19.8 million tonnes to 24.1 million tonnes and a corresponding decrease in the overall gold grade from 4.25 g/t to 3.76 g/t.Table 4 – Loma Larga Mineral Resource Estimate, Effective as of March 31, 2020CIM 2014 Definition Standards were followed for Mineral Resources.Mineral Resources are reported at an NSR cut-off value of US$55/t.Mineral Resources are estimated using a long-term gold price of US$1,650 per ounce, silver price of US$21.00 per ounce, and copper price of US$3.75 per pound.The formula used to calculate gold equivalence (AuEq) is: (Au g/t x 35.78 + Ag g/t x 0.42 + Cu% x 49.58) ÷ 35.78.  The formula considers estimated metallurgical recoveries, assumed metal prices and smelter, which include payable factors, treatment charges, penalties, and refining charges.Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.Mineral Resources are inclusive of Mineral Reserves.Average bulk density is 2.7 t/m3.Numbers may not add due to rounding.Mineral Reserves and Mine PlanThe estimated Mineral Reserves are shown in the following table and have not materially changed from the 2019 FS as the NSR cut-off of $60/t remains consistent with that used in the 2019 FS. The estimated gold price of $1,400 per ounce has increased from $1,250 per ounce used in the 2019 FS. Therefore, the  projected mine plan and estimated production rates and mine life remain unchanged from the 2019 FS.Table 5 – Loma Larga Proven and Probable Mineral Reserve Estimate, Effective as of March 31, 2020CIM 2014 Definition Standards were followed for Mineral Reserves.Mineral Reserves include long hole and drift-and-fill stopes as well as development in ore.Mineral Reserves are reported at an NSR cut-off value of US$60/t.Mineral Reserves are estimated using a long-term gold price of US$1,400 per ounce, silver price of U$18.00 per ounce, and copper price of US$3.00 per pound.Average bulk density is 2.7 t/m3.Numbers may not add due to rounding.The underground mine will be accessed by a 1.2 kilometres long (5 metres high by 5 metres wide) ramp into the deposit. The ramp will serve as the access to the mine for personnel and materials, the haulage of waste and ore, and for ventilation. Due to the high-grade nature of the ore body and the positive geotechnical conditions, the deposit will primarily be mined by the long-hole stoping method, with 20 metres wide, 25 metres high and 20 metres long stope sizes. Certain zones will utilize the drift and fill method where appropriate.Initial daily ore production of 3,000 tpd is planned from primary and secondary stopes for the first four years, generating approximately 1,095,000 tonnes of ore annually. From year 5, daily average ore production of 3,400 tpd is planned to be achieved through plant optimization, generating 1,241,000 tonnes of ore annually. The production averages in the tables below do not include partial production years and have not changed from the 2019 FS. Note that calculations related to by-products where gold equivalent production is disclosed will be lower as a result of the higher gold price used in the calculation.The Company’s discovery in 2017 of ore-grade mineralization up to 300 metres to the west of the current Mineral Resources, the findings of a detailed re-evaluation and study of the deposit, as well as the potential of the entire Loma Larga property, demonstrate that the deposit remains open in most directions with potential to increase Mineral Resources along strike and at depth, both of which remain largely untested, and to find additional deposits on the property.Table 6 – Life of Mine Production StatisticsTable 7 – Peak Production StatisticsTable 8 – Average Annual First Four Full Years Production StatisticsTable 9 – Average Annual Life of Mine Production Statistics4ProcessingOre will be processed using primary and secondary crushing, a ball mill, and a two stage sequential flotation circuit to recover gold, silver and copper into two separate saleable concentrates which will be trucked to the port for export. No cyanide will be used in the extraction process and it is anticipated that acid will not need to be trucked to site. The processing facility and infrastructure have not changed from the 2019 FS and have been relocated to an area closer to the mine site.Extensive metallurgical test work completed for the 2019 FS demonstrated estimated overall gold, silver and copper recoveries into concentrate of 90%, 95%, and 96%, respectively. The average grades of the concentrates are shown in the table below and will differ from the averages depending on the mined head grade. The estimated mass pull is 14%, with an estimated 13.3% reporting to the gold pyrite concentrate and 0.8% reporting to the gold/copper concentrate. The concentrate is expected to have a moisture content of 8-10%.Table 10 – Concentrate ProductionConcentrate SalesDuring the execution of the 2019 FS, concentrate samples and assays were sent to a number of smelters for analysis in order to receive purchase price indications based on the potential grades and quantities estimated during the FS. INV Metals has incorporated revenue indications into the economic estimates of the FS and is confident the concentrates are marketable based on current market conditions and existing port regulations and restrictions. The payabilities used for the concentrates within the financial model remained unchanged from the 2019 FS and were 80% gold and 60% silver for the gold pyrite concentrate and 88% gold, 82% copper and 80% silver for the gold/copper concentrate. These payabilities are inclusive of treatment and refining charges and any relevant penalties delivered to the Main Asian Port and may result in non-comparable gross revenue to other studies. Gross revenue under this structure is lower than the gross revenue associated with a structure where treatment charges, refining charges and penalties are expressed separately.Capital ExpendituresInitial capital expenditures are estimated at $315.5 million (including taxes and duties), up $6 million from the 2019 FS, mainly due to inflation escalation related to process equipment as updated cost estimates were obtained, and increased preliminary earthworks for the tailings storage facility. Sustaining and closure costs are estimated at 82.9 million (excluding taxes and duties), a slight decrease from the 2019 FS due to the tailings facility enclosure costs incurred earlier in the mine life. Pre-production capital expenditure per gold equivalent ounces mined is $111.18, while sustaining capital per gold equivalent ounces mined is $23.64.Table 11 – Capital Expenditure SummaryTable 12 – Sustaining Capital and Closure CostsOperating CostsLoma Larga is forecasted to be a low-cost operation with estimated adjusted operating costs of $71.79/tonne of mined mineralized material. The table below highlights estimated LOM operating and capital costs. The FS contemplates marginally lower mining costs due to the decrease in material handling costs as a result of the mill and process facilities located closer to the mine site.All-in sustaining costs and all-in costs have increased slightly from the 2019 FS, primarily due to an increase in estimated royalties payable due to the higher in revenue as a result of a higher gold price, somewhat offset by lower estimated mining costs.Table 13 – LOM Operating and Capital Costs      1.        Operating and capital costs are presented pre-tax.
      2.        Treatment and refining charges have been estimated based on the payabilities and treatment and refining charges observed on comparable projects.
      3.        Payable gold ounces have been estimated based on estimated comparable treatment and refining charges.
InfrastructureNo material changes to support infrastructure designs were contemplated in the FS. The Loma Larga deposit will be accessed predominately by existing public road infrastructure, which will be upgraded and widened as required. Bypass roads will be constructed where widening of the current road is not feasible. New roads will be constructed to the portal access site and within the process plant and tailings facilities which are within the surface rights owned by INV Metals.Power to the Project will be supplied through construction of a power line, which will connect into the regional electricity grid.Technical InformationThe FS was led by DRA and was prepared in accordance with NI 43-101.
