FEASIBILITY STUDY OVERVIEW

Study Details

The Feasibility Study supports a high-grade 800 tonne per day underground mining operation with designed stopes containing 1.0 million ounces of Probable Mineral Reserves.  The project benefits from significant mining, milling and tailings infrastructure already in place, resulting in one of the lowest capital intensity, undeveloped gold projects in the world.  Mining will be conducted from new ramp development utilizing a combination of cut and fill and longhole mining methods.   A new hoist house and double drum production hoist will use the existing shaft infrastructure to hoist ore and waste from the mine, commencing in year four of operations.

The Madsen implementation schedule spans a period of 13 months, with underground mine development commencing approximately 9 months before the first gold pour.  The project requires initial capital of C$95M (including contingency) to support the construction of an underground mine and associated infrastructure, including the expansion of existing milling capacity to 800 tonnes of ore per day.  The mine is expected to produce peak annual production of 125,000 ounces with LOM all in sustaining costs of US$787/oz Au, which are below industry average.

JDS Energy and Mining Inc. led the Madsen Gold Project Feasibility Study, which included contributions from industry-leading consultants such as Knight Piésold Ltd., Nordmin Engineering Ltd., MineFill Services Inc., Integrated Sustainability, Lorax Environmental Services Ltd, Ginto Consulting Inc., and Equity Exploration Consultants Ltd.

The Feasibility Study results show that the Madsen Gold Project has the potential to remain strongly profitable at lower metal prices, and is robust across a range of capital and operating cost sensitivities.

Mineral Resource

The Company`s February 2019 mineral resource estimate forms the basis for the Feasibility Study.  The resource estimate, prepared by Ginto Consulting Inc. is based upon the mineral resource estimate disclosed on February 5, 2019, which contains the results of 14,822 core drill holes.  Of those, 13,258 drill holes informed the resource estimate with an overall average spacing of 6.4 metres in the high-grade domains.

The updated mineral resource estimate for Madsen is reported at a 4.0 g/t Au cut-off effective February 5, 2019.

Mineral Resource Statement for Madsen Gold Project*

Mining and Mineral Reserves

The Feasibility Study mine plan utilizes a combination of conventional cut & fill (59%), mechanized cut & fill (16%) and longhole mining (25%) methods to extract mineral reserves.  Preliminary mining shapes were developed using a Mineable Shape Optimizer with a cut-off of 4.75 g/t gold, except in the McVeigh Zone which was developed using a 4.0 g/t cut-off.  These MSO shapes were used to guide development of the feasibility mine design plan.  Final stope shapes and mine access development were individually modelled and evaluated to form the final mineable reserve.  A mining recovery of 95% and a dilution of 10% has been assumed for retained tonnes forming part of the mine plan.  The total Probable Reserve mined over the course of the mine life is 3.5 million tonnes at an average diluted head grade of 9.0 g/t for 1.0 million ounces of gold. 

The Probable Mineral Reserves were based exclusively on Indicated mineral resources from the Madsen deposit.   Mineral resources from Russet South, Fork and Wedge were not considered for the Feasibility Study, but will be considered in the forthcoming Preliminary Economic Assessment of these deposits, expected to be issued in February.

Probable Mineral Reserves for the Madsen Gold Project

All ramp and level waste development is to be performed by an owner-operated fleet of one and two boom electric hydraulic drill jumbos, 3.0 cubic-metre bucket LHD’s, 20 tonne haul trucks, scissor lift/bolters and other rubber tired support equipment. Mining will be facilitated by a combination of diesel and battery-powered equipment, with diesel equipment being utilized for upper levels of the mine prior to refurbishment of the existing shaft and installation of a new double-drum production hoist. The use of battery-powered equipment in the mine will eliminate emissions associated with the movement of ore and waste and will result in materially reduced ventilation and heating requirements.

Processing

The existing mill and tailings management facility will be upgraded to achieve mill production of 800 tonnes per day.  Upgrades include modernization of controls and instrumentation, installation of new pumps, two new batch gravity concentrators as well as expansion of the grinding circuit through replacement of the existing ball mill to achieve forecast productivity. 

The process plant will include one stage of crushing and two stages of grinding to achieve a final grind size of 75 µm.  Based on recent metallurgical test work, the optimized flowsheet will include gravity concentration followed by cyanide leach, carbon adsorption/desorption and electrowinning with an overall recovery of 96% expected on a mill feed that will average 9.0 g/t gold over the life of mine.  The product from electrowinning will be refined in an induction furnace to produce gold doré bars. Leached slurry from the carbon-in-pulp (“CIP”) circuit will be treated with the SO₂/Air cyanide destruction process, and the final tailings will be processed and utilized underground as hydraulic fill or pumped to the tailings management facility (“TMF”).

Capital Costs

The Madsen Mine benefits from significant existing infrastructure resulting in a very low capital intensity project.  Total pre-production capital cost (capex) is estimated at C$94.7 million (US$71.0M), inclusive of a C$8.1 million contingency.  The total life of mine capex is C$327 million (US$245M), inclusive of closure costs. 

Underground mining and haulage is anticipated to be completed using an owner-operator development model operating 365 days per year.  Life of mine, purchased equipment results in higher capital expenditures but offers lower long-term operating costs, greater flexibility and better cash flows.

LOM sustaining capital costs are estimated at C$232 million with the majority of the costs associated with underground mine development.

Project Enhancement Opportunities

The Feasibility Study, focused exclusively on the Madsen Deposit, outlines a high-grade, low capital mining operation with 1.0 million ounces of Probable Mineral Reserves.  Exploration by the Company to date has demonstrated that the Madsen Gold Project has outstanding potential for growth and opportunities for scalability.  Key opportunities include:

• The Feasibility Study does not consider mineral resources at Russet South, Fork or Wedge.  A Preliminary Economic Assessment of these additional resources is nearing completion and is expected in the coming weeks;
• Expansion of the Madsen Mine resource, through application of the Company’s geologic model to target extensions to the known resource, including potential:
  • Conversion of the inferred resources in the Madsen deposit to measured and indicated, currently totaling 241,000 ounces (0.9 million tonnes at 8.4 g/t gold)
  • Extensions to the high-grade 8 Zone which remains open for expansion and is scheduled to commence mining in year four of operations
  • Depth extensions of the Madsen deposit which remains open as supported by drill hole PG17-456 which intersected 34.6 g/t gold over 4.3 metres at a depth of 1,373 metres below surface, and AD-11-01 which returned 14.3 g/t gold over 2.0 metres at a depth of approximately 2,100 metres below surface;¹
• Continue exploration at Russet South, Fork, Wedge, and across the +5 kilometre mineral system in place at Madsen, where strong potential exists for continued growth; and
• Review and optimization of the mine plan with an opportunity for additional mine flexibility, potential for increased milling rates and annual gold production.

Environmental and Permitting

The Company benefits from existing environmental authorizations and permits which allow for operation of a 1,089 tonne per day mill and CIP circuit with discharge of treated tailings to the existing tailings facility, dewatering via the existing shaft, and a mine closure plan.  Certain permits will require updating or amendments prior to the commencement of new mining activities including the existing Certificate of Approval (“C of A”) for industrial Sewage Works (tailings and effluent), the C of A for Air and Noise, and the mine closure plan.  Baseline studies and documentation for these amendments are well advanced, with the first amendment filed in August of 2018 (C of A for Air and Noise).   No environmental assessment is anticipated and the Company anticipates having all of the required permits for production in place by Q4 2019 or earlier.

Development Schedule

The proposed project development allows for 13 months for the project execution, which includes de-watering, pre-production mine development, procurement, construction and commissioning. Assuming the project execution starts in April of 2019, the first gold production would be expected in May of 2020.

Key project execution schedule milestones include the following:

Next Steps

With the Feasibility Study now completed, Pure Gold will advance the Project towards development.  In August 2018 the Company announced that it had appointed Endeavour Financial as its financial advisor to provide advisory services with respect to debt financing for the construction and development of Madsen.   This process is well advanced and discussions are underway and advancing with multiple potential financiers. 

Over the coming months, the Company will be focused on:

• Continue working with First Nations to promote a cooperative and mutually respectful relationship concerning Pure Gold’s development plan, and to finalize an agreement to facilitate this relationship;
• Finalization of the Preliminary Economic Assessment of the Company’s satellite resources including Russet South, Fork and Wedge, expected to be issued in the coming weeks;
• Advancing project finance opportunities;
• Optimization of the project execution schedule, including procurement and permitting;
• Ongoing environmental studies and documentation to support the update and filing of existing permits and filing for additional permits that may be required; and
• Commencement of detailed engineering and design activities.
