Vancouver, March 12, 2019 – Leagold Mining Corporation (TSX:LMC; OTCQX:LMCNF) (Leagold or the Company) announces that it has filed the report entitled “Independent Technical Report for the Los Filos Mine Complex, Mexico” which presents the results of the Expansion Feasibility Study (Expansion Feasibility Study) under the Company’s profile on SEDAR at www.sedar.com. The Expansion Feasibility Study was prepared by independent consultants and incorporates the potential for: development of the Bermejal underground mine, enlarging the Los Filos open pit, re-phasing of the Bermejal open pit into two distinct sections (Bermejal and Guadalupe), and constructing a carbon-in-leach (CIL) processing facility to complement the existing heap leach facilities.

Highlights of the Expansion Feasibility Study include:

• Gold production of 3.2 million ounces (Moz) over a 10-year mine life (2019 to 2028) at an average AISC¹ of $740/oz
• Post expansion (2021 onwards):
  • Average annual production of 350,000 oz at AISC¹ of $694/oz
  • Average annual production exceeding 420,000 oz from 2021 to 2024
• Proven and Probable mineral reserves of 104.2 Mt at 1.31 g/t containing 4.5 Moz²
• Capital cost of $180 million to develop Bermejal underground and construct a new 4,000 tonne per day (tpd) CIL plant with related infrastructure
• Current operations to fund capitalized stripping during the initial expansion phase (2019 to 2020) at the Guadalupe and Los Filos open pits
• At $1,250/oz gold price:
  • NPV_0% of $884 million
  • NPV_5% of $679 million
  • IRR of 86%

Leagold CEO Neil Woodyer commented: “Since providing the summary results of the Expansion Feasibility Study in January 2019, our team working with the independent consultants has continued refining the new operating strategy which includes re-phasing the Bermejal open pit, expanding the Los Filos open pit, operating two high-grade underground mines, adding a CIL plant to process the higher-grade ore, and continuing heap leaching of the lower-grade open pit ore. The result of this work is a significant increase in net cash flow to $884 million.  The Los Filos expansion is clearly a project we should proceed with, and we are advancing with construction planning, optimizing the sequencing of the major expansion projects as part of our financial planning, and discussing the social and economic benefits created by the expansion with our employees, contractors, unions and community members.”

Bermejal underground has an approved environmental impact assessment (EIA) and the restart of development is fully permitted. The EIA for the CIL plant and tailings deposits has also been approved, subject to confirmation of final locations of both facilities, and the EIA for the Guadalupe phase of the Bermejal open pit has been submitted for approval. With many of the required approvals in place or well advanced, the Los Filos Expansion can start shortly after Leagold makes its final investment decision.

Summary results of the Expansion Feasibility Study were previously announced on January 16, 2019 (January Summary Results) and, during the completion of the Expansion Feasibility Study report, several more opportunities to enhance the plan were identified. The open pit designs have been further optimized leading to a 10% increase in open pit ore grades to 0.89 g/t from 0.81 g/t, with a 9% reduction of total open pit material mined.  While total gold production is minimally reduced, the optimized open pit designs reduce mining costs and improve cash flow generation. Processing costs were also reduced with lower volumes of low-grade material being processed and from unit cost reductions due to a refined costing approach that recognizes the current heap leach costs at Los Filos will normalize to lower levels over time.   

At $1,250/oz gold price, the expanded Los Filos Mine Complex’s life of mine is expected to generate net cash flow of $884 million, which has increased 18% or by $132 million as compared to the $752 million reported in the January Summary Results. The mineral reserve estimates are based on a gold price of $1,200/oz gold and were evaluated by SRK using cashflow modeling at that price and found to be economic. 

Figure 2 illustrates the key updates that contribute to this increase in net cash flow and a summary description of the key updates is included below.

Optimization of Open Pit Designs:  The open pit Mineral Reserves have been updated following disclosure of the January Summary Results as a result of further work undertaken to optimize the pit designs by reducing the amount of lower-grade marginal material being mined.  With the refined designs, the average gold grades of the open pit Mineral Reserves have increased to 0.88 g/t or by 10% as compared to the previous 0.80 g/t.  In addition, the total open pit material mined has been reduced by 50 million tonnes.  Table 1 states the Los Filos Proven and Probable mineral reserves as of October 31, 2018, and for the avoidance of doubt, the majority of discussion of the Expansion Feasibility Study in this news release relates to the period of January 1, 2019 to the end of the mine life.

Notes:
¹ CIM (2014) definitions were followed for Mineral Reserves.
² Mineral Reserves for Bermejal Underground were prepared by SRK Consulting (Canada) Inc. Mineral Reserves for all other deposits were prepared by the Los Filos Mine Complex and reviewed by SRK.
³ Mineral Reserves are quoted using a NSR break-even cut-off grade approach with minimum block NSR of $149.4/t for Bermejal underground. Cut-off grade for the Los Filos underground is 2.59 g/t. Mineral reserves for Los Filos, Bermejal and Guadalupe open pits are based on variable break-even cut-offs for ore revenue as generated by process destination and recoveries. Variables for revenue calculation include process cost, recovery, and estimated gold, copper and sulphur grades.
⁴ Mineral Reserves are based on Measured and Indicated Mineral Resources.
⁵ Metal price assumption for gold was US$1,200/oz.
⁶ Tonnage and grade measurements are in metric units. Contained gold are reported as troy ounces.
⁷ Summation errors may be present due to rounding.

Decreased Gold Revenue: As a result of the open pit mine plan optimization to maximize cash flow generation, the LOM total gold production has decreased by less than 1% to 3.240 million ounces (Moz) as compared to January Summary Results.  At $1,250 gold price, this is a reduction of approximately $37 million in life of mine gold revenue.

Increased Silver Revenue: The increase of $16 million in revenue from silver sales is primarily the result of increased silver production to 5.3 Moz as compared to 4.1 Moz from the previously announced summary results.  The increase in silver production is primarily due to increased silver recovery rates from heap leach processing to between 9 and 14%, which are in line with current performance on the heap leach pads and supported by metallurgical test work required by the independent consultants.

Reduced Mining and Processing Costs: Total mining and processing costs have been reduced by $78 M and $146 M, respectively. The reduction in mining costs is directly related to the 50.0 Mt reduction in open pit material mined with the optimized design.  The reduction in processing costs is attributable to both the reduced volume of material processed and a reduction in the LOM average unit processing costs for the heap leach pads from $5.5 to $4.4 per tonne processed.  This unit cost improvement is primarily due to a refined costing approach that recognizes the current costs at Los Filos will normalize to lower costs levels once the practice of applying additional lime to raise the pH level of previously leached ore within the heap leach pads and the need to apply additional cyanide leaching solution is reduced. Cyanide consumption and lime addition are the major contributors to the processing cost.  Lime addition is currently added at double the required quantity to address the low pH and subsequent cyanide losses through volatilization. Cyanide losses are also attributed to solution application to leached areas of the heap.  Operational measures are being implemented to reduce the cyanide consumption by eliminating solution application to leached areas of the heap and the creation of an inter-lift liner through compaction of the previously leached heap surface.  Reduction in over-irrigation of leached areas has reduced the daily cyanide consumption from 60 tonnes per day to 45 tonnes per day.  The compaction of the leach surface and the installation of new solution collection pipes will allow pregnant leach solution to report directly to the pregnant solution ponds without having to percolate through the entire heap.  This in turn will result in a higher pH solution with excess cyanide reporting to the pregnant solution ponds.  This impact will increase the entire heap solution pH and circulating free cyanide resulting in a reduction of lime and cyanide addition.

Increased Mining Duties and Taxes: Due to the increase in the forecasted margin generation and profitability, the calculated income and mining taxes payable also increase by $94 million over the life of the mine.

Expansion Capital

The $180 M total expansion capital cost estimate is comprised of Bermejal underground mine development for $65.4 M, construction of the 4,000 tpd CIL plant for $76.3 M, and $38.4 M for site infrastructure including a tailings filtration system, 40MW substation, and transmission line (Table 4), which is not significantly changed from the January Summary Results.  However, the optimization of the open pit design has significantly reduced the investments needed for capitalized stripping to $37.1 M from $50.4 M.

All-in Sustaining Costs

This news release refers to expected AISC per ounce which is a non-GAAP (generally accepted accounting principles) measure however is a measure the Company believes more fully-defines the total costs associated with producing gold. This measurement has no standardized meaning under International Financial Reporting Standards (IFRS) accordingly there may be some variation in method of computation of “all-in sustaining costs” as determined by the Company compared with other mining companies. AISC reported by Leagold includes mine cash costs, land access payments, royalties, and sustaining capital expenditures, but excludes non-sustaining capitalized stripping and end of life reclamation costs. The LOM AISC of $740/oz increases to $756/oz if end of mine life reclamation costs are included in accordance with the World Gold Council guidance on AISC.

This measurement is intended to provide additional information only and should not be considered in isolation or as a substitute for measures of performance prepared in accordance with IFRS.
