(All amounts in US dollars, unless otherwise indicated)
Vancouver, January 16, 2019 – Leagold Mining Corporation (TSX:LMC; OTCQX:LMCNF) (Leagold or the Company) reports that a Feasibility Study (Expansion Feasibility Study) prepared by independent consultants for the expansion of the Company’s Los Filos mine in Mexico is now complete. The Expansion Feasibility Study incorporates the potential for: development of the Bermejal underground mine, enlarging the Los Filos open pit mine, re-phasing of the Bermejal open pit into two distinct open pits (Bermejal and Guadalupe), and the construction of a carbon-in-leach (CIL) processing facility to complement the existing heap leach facilities.
- Gold production of 3.3 million ounces (Moz) over a 10-year mine life (2019 to 2028) at an average AISC1 of $795/oz
- Post expansion (2021 onwards):
- Average annual production of 350,000 oz at AISC1 of $759/oz
- Average annual production exceeding 400,000 oz from 2021 to 2023
- Proven and Probable mineral reserves of 111.3 Mt at 1.23 g/t containing 4.5 Moz2
- Capital cost of $180 million to develop the 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:
- NPV0% of $752 million
- NPV5% of $565 million
- Expansion capital payback period of less than 1 year
- IRR of 87%
Leagold CEO Neil Woodyer commented: “When we acquired Los Filos in April 2017 from Goldcorp, we identified its potential to be developed into a long life, low-cost operation with significant scale. During the 20 months since the acquisition, we have carried out extensive exploration programs for both open pit and underground deposits, developed a 1,330-metre ramp to access the ore body at Bermejal underground, completed the Bermejal underground mine design, completed comprehensive metallurgical test work on all of the mineral deposits to support the CIL plant design, and learned a lot from current operations. Our investment in this work to date is approximately $30 million and forms the basis of the independent Feasibility Study and a 43â€'101 technical report.
“The study forecasts a 10-year mine life with annual gold production approximately doubling from current rates. The Los Filos mineral reserves have increased to 4.5 Moz2, from 1.7 Moz3 at the acquisition in 2017. Los Filos also has abundant mineral resources that provide additional opportunities for adding to the increased reserves and further extending the mine life. We intend to carryout additional exploration programs designed to extend mine life.
“The study identifies a new operating strategy which includes three large open pits, two high-grade underground mines, the addition of a CIL plant to process the higher-grade ore, and the continued heap leaching of the lower-grade open pit ore. The Los Filos expansion will also benefit from existing operations and excellent infrastructure. Approximately 51% of the gold production in the life of mine plan is from the CIL plant and 49% is from the existing heap leach facility.
“With this very positive study completed, we are now putting its findings into our overall corporate business model for planning and corporate financing purposes. It is obviously a project we should undertake and therefore we are preparing a Los Filos development plan that includes construction planning, optimizing the sequencing of the major expansion projects, and recognizing the social and economic benefits created by the expansion opportunities and the engagement required from employees, contractors, unions and community members.
“The Los Filos acquisition and this expansion plan illustrate the benefits and success of our buy and build strategy.”

The site-wide LOM plan for the Los Filos mine complex has contributions from two high-grade underground mines and three large, lower-grade open pits.
Bermejal underground mine design and cost estimation was completed by SRK Consulting (Canada) Inc. A total of 11 kilometres (km) of horizontal and vertical development will be completed during the initial development period and a further 45 km of development over the life of mine. The mine life extends for nine years producing 6.4 million tonnes (Mt) at 6.57 grams per tonne (g/t) for contained gold of 1.348 Moz (Proven reserves of 0.4 Mt at 7.50 g/t for 0.095 Moz gold and Probable reserves of 6.0 Mt at 6.51 g/t for 1.253 Moz gold). Mining costs of $99 per tonne are based on contractor mining. The mining method is underhand drift and fill with cemented rock fill (CRF) used as backfill. Bermejal underground will have a dedicated CRF production plant. The production rate averages 2,000 tonnes per day (tpd) and peaks at 2,150 tpd. Bermejal underground contributes 31% of the contained gold in the LOM plan.
Los Filos Underground
The Los Filos underground mine is currently operating at over 1,800 tpd and in the LOM plan averages 1,700 tpd with mining costs of $73 per tonne based on owner and contract mining. Reduced operating costs, improved mining efficiencies and additional drilling have enabled the update of the Los Filos underground mine plan to extend to 2021. The reserves are 1.9 Mt at 5.50 g/t for a total of 0.338 Moz gold (Proven reserves of 0.8 Mt at 5.34 g/t for 0.144 Moz gold and Probable reserves of 1.1 Mt at 5.63 g/t for 0.194 Moz gold).
Open Pit Mining
Los Filos utilizes conventional open pit mining methods with an owner-operated fleet supplemented with rental of additional equipment during peak production periods. The average open pit mining costs are $1.41 per tonne mined.
Los Filos Open Pit
The expanded Los Filos open pit has a Proven and Probable reserve of 42.7 Mt at 0.57 g/t containing 0.776 Moz (including dilution and recovery; Proven reserves of 34.1 Mt at 0.59 g/t for 0.645 Moz gold and Probable reserves of 8.6 Mt at 0.47 g/t for 0.131 Moz gold). The mine life was extended seven years to 2027. The Los Filos open pit has an overall strip ratio of 4.0.
Bermejal and Guadalupe Open Pits
The Bermejal and Guadalupe open pits have been split into two open pits and rescheduled to mine the higher-grade Guadalupe ore earlier in the schedule which significantly improves the economics. Guadalupe has a Proven and Probable mineral reserve of 26.3 Mt at 1.55 g/t Au for 1.313 Moz (Proven reserves of 0.2 Mt at 0.35 g/t for 0.003 Moz gold and Probable reserves of 26.1 Mt at 1.56 g/t for 1.310 Moz gold). A pushback in 2020 will open this up as a separate open pit that has a 10-year life. The Guadalupe pit has an overall strip ratio of 8.0.
The Bermejal open pit extends for at least five years to 2025 based on the current reserves. Proven and Probable mineral reserves are 34.0 Mt at 0.54 g/t Au for 0.588 Moz (Proven reserves of 1.3 Mt at 0.47 g/t for 0.019 Moz gold and Probable reserves of 32.7 Mt at 0.54 g/t for 0.569 Moz gold). The overall strip ratio of the Bermejal open pit is 2.7.

|Contribution, contained gold||%||51%||21%||28%||100%|
Additional opportunities for adding to resources and reserves include the south end of the Bermejal open pit, extensions to the southwest side of Bermejal underground and the continuation of the high grade mineralized zone below the Guadalupe open pit.
CIL and Heap Leach Processing
The CIL plant is expected to achieve higher recoveries (an average of 89.7%) and better financial returns than heap leach processing for the underground ore and the higher-grade portion of the open pit ores. The plant also provides the ability to process some ore types that were previously not included in reserves as they were not amenable to heap leach processing; this includes material with an elevated sulphur content which exhibits lower gold recoveries at the crush sizes typically used in crushing for heap leach processing. The plant is predicted to process a total of 12.4 Mt at an average grade of ore feed of 4.63 g/t gold with an average recovery of 89.7% to produce 1.658 Moz gold.
The Expansion Feasibility Study contemplates the existing heap leach facility continuing to operate throughout the full LOM plan. A total of 95.6 Mt of ore with an average grade of 0.79 g/t gold will be placed on the leach pads and have an average recovery of 61.9% to produce approximately 1.500 Moz gold.
Secondary recovery is expected to contribute an additional 0.111 Moz from surface re-leaching and re-handling of previously leached ore.
Contributions to the gold production in the LOM plan are 51% from the CIL plant, 46% from the heap leach and 3% from secondary recovery (Table 4).
Table 4: Los Filos Processing (from Jan 1, 2019 to LOM)
|Item Description||Units||CIL||Heap Leach||Secondary Recovery||Total, Processing|
|Total ore processed||kt||12,416||95,555||-||107,971|
|Contribution, recovered gold||%||51%||46%||3%||100%|
Figure 3: Gold Production Profile, by Processing Method
The potential for addition of a SART (sulphidization, acidification, recycling and thickening) circuit in the plant is currently being investigated. A SART circuit would provide an opportunity to reduce cyanide consumption and yield a copper by-product for certain ores with elevated copper levels.
Expansion Capital Cost Estimate
The $179.7 million (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 $38.1 M for site infrastructure including a tailings filtration system, 40MW substation, and transmission line (Table 5).

|Bermejal underground – development capital||65.4|
|CIL plant, including contingency||76.3|
|Tailings filter system||26.1|
|Preparation of Tailings Deposition Area||4.0|
|Total, expansion capital costs||179.7|
|Capitalized open pit stripping (2019 to 2020):|
|Guadalupe open pit||30.5|
|Los Filos open pit||19.9|
|Total, capitalized open pit stripping||50.4|
|Operating cash flow, 2019 to 2020 (credit)||(83.3)|
|Surplus operating cashflow (credit)||(32.9)|
|Expansion capital costs, net current operations||146.8|
The Bermejal underground mine utilizes the existing 1,330-metre exploration ramp as its main access ramp and includes an additional 11 km of development. The 15-month pre-commercial development period and the Expansion Feasibility Study assumes this commences in Q2 2019 and extends to Q3 2020 when the production rate sustains 1,100 tpd. Ore produced prior to startâ€'up of the CIL plant will be sent to the heap leach facility.
The existing ramp extends from 1,428 metre elevation at the bottom of the mined-out portion of the Bermejal open pit to 1,238 metre elevation; mineralization extends to at least 770 metre elevation. The Expansion Feasibility Study contemplates sustaining development continuing to 2026 to provide access to all six mineralized areas. Over 75% of the ounces are from the central zone (zone 5) which has the highest grades and widest intervals of mineralization.
The CIL plant has an 18-month construction period plus three months of initial detailed engineering and procurement of long lead-time equipment. The plant includes single stage crushing and SAG grinding prior to the CIL leaching process. As an opportunity to reduce capital costs, the plant utilizes modified facilities at the existing ADR (adsorption desorption recovery) processing plant including an acid wash and elution columns, eluate heating and handling equipment and gold room to recover gold and silver from the CIL-loaded carbon. New, larger, electrowinning cells and rectifiers will be added to handle the higher gold and silver loadings on the carbon.
Tailings are thickened, filtered and washed with low cyanide barren solution for improved water management and long-term storage as dry stacked tailings will be placed in a lined facility at the south end of the heap leach pads. The benefits of dry stack tailings include the recirculation of a high proportion of the process water; minimizing the footprint of the deposition facility and use of stacking of tailings in an area of high seismic activity.
A new 40MW substation with 100% transformer redundancy will satisfy the full electrical requirement for the entire mine site including the CIL plant and the Bermejal underground mine. The substation will be connected to a new 115 kV high voltage power line.
Other major projects include capitalized stripping at the expanded Los Filos, Guadalupe and Bermejal open pits. These projects are being funded by cash flow from current operations as shown in Table 5. The Expansion Feasibility Study contemplates the principal expansion activities as scheduled in Figure 4. The pre-commercial development phase for Bermejal underground extends to Q3 2020, when the underground operation sustains commercial rates of ore production of approximately 1,100 tpd. The construction of the CIL plant is scheduled for 18 months, with commissioning and ramp-up to occur in Q3 2020. The expansion of open pit mining operations, with pre-stripping at Guadalupe and a pushback at Los Filos, is scheduled for 2020. The pushback to expand the Bermejal open pit is scheduled for 2021.
The Bermejal underground has an approved EIA (environmental impact assessment) and the restart of development is fully permitted. The EIA for the CIL plant and tailings deposits has also been approved. The permits to commence construction of the CIL plant and tailings deposits will require satisfaction of customary conditions, and are expected within the study development timeline.

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 $795/oz increases to $811/oz if end of mine life reclamation costs are includedin 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.
This news release refers to expected total cash costs which are a common financial performance measure in the gold mining industry however it has no standard meaning under IFRS. The Company reports total cash costs on a per ounce sold basis. The Company believes that, in addition to conventional measures prepared in accordance with IFRS such as costs of sales, certain investors use this information to evaluate the Company’s performance and ability to generate operating income and cash flow from its mining operations. Management uses this metric as an important tool to monitor operating costs. Adoption of the standard is voluntary and other companies may quantify this measure differently because of different underlying principles and policies applied.
