- Along with key partners and industry experts, Foran is currently developing a number of exciting business initiatives with updates on these developments expected throughout the year.
Dan Myerson, Foran's Executive Chairman & CEO commented;
"The completion of the FS is truly an excellent accomplishment by the entire team at Foran. It is important to be mindful that the study showcases only a snapshot in time of what our initial mine and centralized mill will look like, as we envision scaled expansions and future growth while sequencing in other deposits across the district.
As we continue to de-risk McIlvenna Bay with the ongoing advancement of the exploration decline, permitting, project financing, and our continued dynamic exploration campaign, I believe we are still in the early innings of understanding what this remarkable district has to offer. McIlvenna Bay is expected to be the centralized mill that could be expanded in phases as we continue to explore, define and potentially develop near-mine deposits and more within a 50km radius. Our land package is over 1,450 km², providing us with the canvas to explore in a systematic way. The neighbouring Flin Flon district has been operating for close to a century, and it is our vision to transform the Hanson Lake District into the next multi-decade mining camp.
Critically, Foran will be resolute in our effort to operate a mine of the future, targeting carbon neutrality and creating a sustainable asset for local communities in a decarbonizing world. Having the opportunity to power our site using renewable energy (hydropower), we are in a good position to deliver on our targets. Additionally, Foran will continue and always strive to be grateful, respectful and ensure a collaborative relationship with local communities, as this is essential in creating long-term mutually beneficial success. We are focused on education and training of local people to provide employment opportunities and build transferable skills. As the world continues to decarbonize, Foran will continue to search and evaluate circular economy opportunities, and pioneer ESG business initiatives to generate superior investment returns.
As the world hunts for new copper projects to satiate the urgent necessity to decarbonize our planet, geopolitical risks globally are impacting direct investment in regions where government regimes and taxation remain constant uncertainties. Operating in a global leading mining jurisdiction that is Saskatchewan further proves the amazing advantage Foran is fortunate and grateful to have. I am very proud of our team's accomplishments, and we look forward to delivering more exciting news throughout 2022 as we work towards our goals of building the next prolific mining jurisdiction in the world."

Project Description
The McIlvenna Bay project is located in east-central Saskatchewan approximately 375km northeast of Saskatoon, and 85 km West of Flin Flon Manitoba, and is accessible year-round via a 18km all-weather road connected to Saskatchewan Provincial Highway 106.
The FS outlines a project designed to be a decline/shaft underground mining operation utilizing long-hole mining methods for ore extraction. Ore is expected to be processed via conventional single stage crushing circuit with a semi-autogenous grinding ("SAG") mill and ball mill design. Grinding is planned to be followed by a flotation circuit to produce both a copper and zinc concentrate for transportation from site to Flin Flon for shipment by rail to Canadian smelters and/or offshore.
The deposit at McIlvenna Bay includes several zones and two distinct styles of mineralization, typical of volcanogenic-hosted massive sulphide ("VHMS") deposits, massive sulphide mineralization and stockwork-style mineralization in the Copper Stockwork Zone ("CSZ"). The massive sulphide is a continuous mineralized horizon which averages 3.5m in thickness while the CSZ averages a thickness of 12.0m. The massive sulphide and the underlying CSZ are generally in contact with one another throughout the deposit, giving the bulk of the deposit an average thickness of 15.5m overall.
The capital and operating cost estimates in the FS reflect the current inflationary pressures being faced by the industry globally, however the relatively light capital intensity associated with the project helps mute the overall impact inflation has on economics, which remain robust.
McIlvenna Bay Project Bankable Feasibility Study
The FS was led and compiled by Stantec Inc. as the lead author. Stantec completed the detailed mine design and engineering, with Halyard Inc. completing process plant, paste plant and surface support infrastructure design. Knight Piésold worked in conjunction with both Stantec and Halyard on the Dry Stack Tailings Management Facility Design. RockEng prepared the geotechnical model, working closely with Stantec and the Foran site team. The McIlvenna Bay Mineral Resource estimate was prepared by Micon International Limited, and the Mineral Reserve estimate was completed by Stantec.

Mineral Reserve Estimate
The 2022 Mineral Reserve Estimate was prepared by Stantec Inc., with an effective date of February 23, 2022. Reserves total 25.7Mt, a 127% increase from its 2020 Reserve estimate of 11.3Mt. This represents a 66% reserve conversion rate from the existing 39.1Mt of indicated resources (vs. 49% reserve conversion from the prior 2019 resource estimate). The higher conversion rate is attributable to optimized mine design, which includes a reduction in minimum mining widths from 3.8m to 3.0m, and a lower net smelter return ("NSR") cut-off value, and higher commodity prices.
Reserves grade of 1.23% Cu, 2.39% Zn, 0.47 g/t Au and 15.3 g/t Ag use a US$90/t NSR cut-off. These compare to 2020 reserve grades of 1.14% Cu, 4.01% Zn, 0.54 g.t Au and 21.0 g/t Ag using a US$100/t NSR cut-off. The decline in by-product grades are predominantly attributable to the significant reserve additions for the Copper Stockwork Zone, which has higher copper grades and lower zinc grades than the Massive Sulphide Lens. Foran sees the opportunity for further reserve upside potential given the deposit remains open at depth and along strike, in addition to higher current commodity prices.
The Mineral Reserve Estimate is estimated using long-term consensus metal prices of US$3.50/lb Cu, US$1.20/lb Zn, US$1,600/oz Au and US$22.50/oz Ag. This compares to the 2019 Reserve Estimate pricing of US$3.30/lb Cu, US$1.25/lb Zn, US$1,310/oz Au and US$16.20/oz Ag. The reserve is summarized in Table 5 below.

2 The base case mineral reserve is estimated based on a NSR cut-off value of US$90/t. NSR value was calculated using Cu, Zn, Au, Ag and high-grade caps were applied and include provisions for metallurgical recovery and estimates of current shipping terms and smelter rates for similar concentrates. Metal prices used are US$3.50/lb. Cu, US$1.20/lb. Zn, US$1,600/oz. Au, and US$22.50/oz. Ag. |

Mining
The FS proposes to mine ore using three different, but similar, longhole mining methods. Most ore will be mined by way of transverse stoping, and some longitudinal and Avoca stoping, depending on the orebody thickness and geometry. These longhole methods involve developing lateral drifts at 30 metre sublevel intervals and drilling holes between the levels and blasting the ore from the upper elevation. The ore will be extracted from the lower elevation of the stopes and transported to surface in the early part of the mine life and will be hauled to underground stations after the shaft is commissioned. Empty stopes will be filled with either paste backfill or waste rock from development headings.
Ore will be moved using battery electric vehicles ("BEVs"), which will help the company achieve its carbon-neutrality goals. The ramped-up 4,200 tonnes per day ("tpd") operation will require a fleet of seven haul trucks and six loaders. The use of BEVs will translate to operating cost efficiencies through reduced fuel consumption, and reduced ventilation and infrastructure requirements while improving air quality for all those working in the mine. Swappable batteries will be charged in special charging stations located underground. Underground development will be undertaken with innovative technology and state-of-the-art computerized development jumbos, which can install ground support, in addition to face drilling.
The FS assumes the company will be able to take advantage of the existing infrastructure associated with the previously announced exploration decline. Given the close proximity of the McIlvenna Bay reserve to surface, the company expects a relatively short timeline to initial ore mining and a relatively quick ramp up. As highlighted in Figure 2 below, the CSZ will constitute approximately 61% of the ore processed, while roughly 39% will be sourced from the massive sulphide zone.
Figure 2 - Ore Processing Source
Production Shaft
Included in the FS is the eventual construction of a production shaft to benefit mine efficiency at depth and to support any potential future resource and mine expansion down dip of the existing resource. Under the current plans, the shaft will the developed in two separate legs. Development of the upper leg is expected to begin in Year 5 with completion of the (loading pocket) in Year 7 at a total cost of C$63.9M, which will lower operating cost in the lower levels of the mine, support future exploration initiatives and potential mine life extension.
The production shaft will be rectangular, extending from surface to a depth of 630m. Lateral development will precede excavation and furnishing allowing for the shaft to be developed from the bottom up in two separate sections resulting in lower cost than a conventional "blind sink" shaft. A pilot and slash method will be utilized for the excavation portion with the equipping of the shaft will be done from the top downwards.
A personnel hoist will also be installed within a separate compartment of the production shaft for improved effective work times and to facilitate a second means of egress from the mine.
Figure 3 - Long Section of Shaft and Underground Workings
Processing & Recovery
The FS proposes ore processing to be conducted using primary crushing with a semi-autogenous grinding ("SAG") mill and ball mill design. The processing facility is expected to have a nameplate capacity of 4,200tpd or 1.51Mtpa. Ore transported from the mine will be dumped directly into the crusher or temporarily stockpiled on a lined pad for future processing.
Cyclone overflow from the grinding circuit, at an 80% passing size of 75 µm, will flow by gravity to the flotation area. Sequential rougher flotation, followed by regrinding and cleaner flotation, will produce a copper concentrate with an average grade of 28% Cu, ~240 g/t Ag and ~10 g/t Au, and a zinc concentrate with an average grade of 50% Zn, ~45 g/t Ag, <1 g/t Au and SiO2 of <1.5%. Both concentrates do not contain any elevated deleterious elements and are considered very clean. The two products are very similar in physical form, being filtered cake (nominally 8-10% moisture) that will be transported in bulk by road to the railhead in Flin Flon, MB. The flotation circuit will also produce a pyrite concentrate that will allow the operation to maintain the sulphur content in the tailings storage facility ("TSF") at a level that prevents acid generation. Low sulphur tailings from the mineral processing facility will be thickened and filtered to reduce the moisture content and trucked to the TSF. The pyrite concentrate and a portion of the low sulphur tailings will be mixed with cement and pumped underground as paste backfill to fill mined-out stopes.
Figure 4 - Copper Equivalent ("CuEq") Production Schedule
Metallurgy
The ore contains chalcopyrite, galena, sphalerite, pyrite and pyrrhotite almost exclusively, with only very minor occurrences of other sulphide minerals observed. Pyrite predominated over pyrrhotite in all ore types. For non-sulphide gangue, copper stockwork contained mostly quartz, mica, and chlorite, while massive sulphide ores contained more carbonates, iron oxides and talc and less quartz. Clay contents were generally low in all ore types. The testwork demonstrated the ore is amenable to conventional flotation and that the two ore types can be blended so that they do not have to be handled separately throughout the operations.
The mineral processing facility will produce clean copper and zinc concentrates that will be saleable to smelters. A program of variability testwork helped to develop head grade vs. recovery relationships for the FS, and these have been applied to the mine production schedule to define concentrate production profiles. Since metallurgical testing commenced in 2012, samples have displayed solid metallurgical characteristics and life of mine average copper and zinc recoveries of 91.1% and 79.8% respectively have been determined. Separate copper and zinc flotation concentrates with grades of 28% Cu and 50% Zn respectively are indicated, and the copper concentrate also carries by-product credits for gold and silver (with recoveries of 88.6% and 63.2% respectively).
Table 6 - Recovery rates
LOM Recovery Rates | Copper | Zinc | Gold | Silver |
Massive Sulphide Ore | 82.4% | 84.4% | 82.9% | 54.6% |
Copper Stockwork Zone | 95.2% | 47.0% | 92.7% | 76.6% |
Blended Recovery Rates | 91.1% | 79.8% | 88.6% | 63.2% |
Power
Power will be supplied to the Project site will be provided in two phases. The first phase, which includes the construction period and initial production period, will be provided via an existing distribution line with approximately 1.2 MW in available capacity, coupled with liquefied natural gas generation. A new 77km dedicated 138 kV transmission line fed from the Island Falls Hydro Generating Station will be constructed and is anticipated to be in service in Year 5, at which point the LNG would be decommissioned. Total connected load power requirements for the mine are expected to be approximately 18.5 MW.
Filtered Dry-Stack Tailings
Process plant tailings will be split into a sulphur deficient stream and a sulphur stream. The sulphur deficient stream would be dewatered to a 15-20% moisture cake and placed within the dry-stack tailings facility, which is located within the previously disturbed reclaimed silica sand quarry. The sulphur tailings stream will be mixed with a Portland cement-based binder and used underground to provide geotechnical support in mined-out areas of the mineral deposit. Reusing tailings for backfill and dry-stacking tailings reduces the mine's environmental footprint.
Capital Expenditures
The FS outlines an initial pre-production capital cost estimate of $368.0M, including a contingency of $38.5 and net of pre-commercial production credits of $7.9M, highlighted in Table 7 below. The largest components of the initial capital cost estimate include $151.5M for mill development and $132.2M for underground mine development. Construction is expected to be completed over a two-year period. Sustaining capital costs over the life of mine are estimated at $481M, which includes $63.9M for shaft development. Over 70% of initial capital cost estimates are based on competitive quotes.
The FS excludes pre-project approval expenditures associated with the previously announced pre-development program (surface preparation and exploration decline) as well early engineering costs. Based on latest estimates, Foran expects these pre-project approval expenditures to total approximately $45M.

Operating Costs
Operating costs are summarized in Table 8 below. Mining costs are estimated at $41.26/tonne mined based on an average mining rate of approximately 1.51Mtpa. Mining costs reflect the blend of lower cost sublevel longhole stoping, and the higher cost associated with longitudinal stoping and Avoca mining. Processing costs are estimated at $23.96/t, G&A at $6.78/t, and tailings at $1.54/t for total operating costs of $73.55/t. Foran's consultants used a first principles methodology in establishing operating costs. Over 70% of material costs are quotes received during H2/21, with productivities being derived from benchmarking and industry best practices. On a per pound basis, C1 copper cash costs are estimated at US$0.26/lb, net of by-product credits, and US$0.90/lb on an all-in sustaining cost basis, net of by-product credits.

Opportunities
Foran has identified various opportunities that have the potential to further improve project economics:
- Automation - Foran will continue to evaluate emerging technologies that could increase automation in the operations to improve efficiency and safety. This could include more autonomous production equipment, as well as support equipment, such as boom trucks for transporting materials underground.
- Remote Operations Centre - Foran is considering installing a control room located offsite, where semi-autonomous equipment could be operated from. Certain other non-production functions could also be performed from this site which would reduce camp and travel costs and potentially help the company to attract and retain top-tier talent.
- Reduced Backfill Costs - Foran will investigate adding locally sourced sand (dolomite) in the backfill to reduce binder cost. While further testwork is required, the geochemical characteristics of the dolomite, combined with the cement used in the paste, creates a stronger product compared to using only tailings. This would result in a lower binder requirement.
- Ore Sorting - Initial testwork conducted on core samples indicated amenability to the sorting technology. More testwork will be undertaken, using material from the planned bulk sample, to investigate sorting in the flowsheet. The benefit would be upgrading ore before it is milled, reducing costs.
- Exploration Potential - The deposit extends down-plunge approximately 2km, where it remains open at depth and along strike. Foran is also turning its exploration focus to advancing regional targets and deposits.
- Potential Expansions - The processing plant is being designed as an initial 4,200tpd plant that could accommodate future potential phased expansions as Foran advances and delineates additional near-mine deposits across the Hanson Lake District.
Environment, Permitting and Communities
The McIlvenna Bay Project is considered a development and must obtain Ministerial approval pursuant to The Environmental Assessment Act (Saskatchewan) before construction can proceed. Foran has already commenced work required for EA approval, and as part of the process the Company must conduct an Environmental Impact Assessment and submit an Environmental Impact Statement ("EIS") for review to the Ministry of Environment.
Upon submission of the EIS, a technical review is completed through the Saskatchewan Environmental Assessment Review Panel, who are tasked with providing advice on the adequacy, accuracy and completeness of the EIS. Following the panel's review and response to comments by Foran, the EIS and final Technical Review Comments are available for public review and written comment for 30 or 60-calendar days. Once the public review period is complete and the Government has completed their Duty to Consult, the Minister of Environment would make a decision on approving the development. After the EA approval is in hand, the Company is able to obtain all other required regulatory permits and licenses, including but not limited to a mine surface lease agreement, construction approvals, and the operating approval.
Carbon Neutrality and ESG
The Company remains committed on delivering a mine of the future, with an initial focus on natural capital initiatives (which includes achieving carbon neutrality) and human capital initiatives. Hydroelectric power, BEVs, and carbon sequestration are expected to be notable drivers in reaching our carbon neutrality goals, while we work closely with local communities that are critical to operate in an evolving and increasingly decarbonized world. The Company is looking forward to updating all stakeholders on our strategy as we move forward with these initiatives.
Project Finance
Foran has received expressions of interest from a various potential financing partners to provide project-level debt and other potential forms of financing to advance the construction of McIlvenna Bay. The company will continue discussions with select potential financing partners in order to finalize the financing package in a timely manner while managing risk and maximizing value for shareholders. The company believes that McIlvenna Bay's top-tier jurisdiction, carbon-neutrality targets, low capital intensity and exposure to strategic commodities makes the project an attractive proposition for potential financing partners.
Mineral Resource Estimate
The FS is underpinned by the Mineral Resource Estimate announced October 14, 2021 (News Release Link). The updated estimate outlined a 70% increase in Indicated resource tonnes to 39.1 Mt compared to the prior 2019 resource estimate of 23.0Mt and Inferred resources totaled 5.0 Mt. The 2021 Resource Estimate is summarized in Table 10 below. Mineralization begins ~25m below surface and extends down-plunge approximately 2km, where it remains open at depth outlining future opportunity to grow the resource.
The mineral resource estimate was completed by Micon International Limited ("Micon") and verified by Mr. William J. Lewis, P.Geo. of Micon, independent of Foran and a Qualified Person as defined within National Instrument 43-101 ("NI 43-101"). The 2021 Resource Estimate's effective date is September 6, 2021, and is estimated using long-term metal price projections of US$4.25/lb Cu, US$1.35/lb Zn, US$1,800/oz Au and US$25.00/oz Ag. The base case uses a US$60/t NSR cut-off using provisions for metallurgical recoveries, smelter payables, refining costs, freight, and applicable royalties, consistent with the cut-off used for the 2019 Resource.

Non-GAAP Measures
This press release includes certain terms or performance measures commonly used in the mining industry that are not defined under International Financial Reporting Standards ("IFRS"), including Copper Equivalent, C1 Copper Cash Costs (net of credits) per pound of payable copper and All-In Sustaining Costs per pound of payable copper, and operating costs per tonne processed. Non-GAAP measures do not have any standardized meaning prescribed under IFRS and, therefore, they may not be comparable to similar measures employed by other companies. The Company discloses "C1 Copper Cash Costs", "All-in Sustaining Costs", "EBITDA", and "Free Cash Flow" because it understands that certain investors use this information to determine the Company's ability to generate earnings and cash flows for use in investing and other activities. The Company believes that conventional measures of performance prepared in accordance with IFRS, do not fully illustrate the ability of mines to generate cash flows. The measures, as determined under IFRS, are not necessarily indicative of operating profit or cash flows from operating activities. The measures cash costs and all-in sustaining costs are considered to be key indicators of a project's ability to generate operating earnings and cash flows. Non-GAAP financial measures should not be considered in isolation as a substitute for measures of performance prepared in accordance with IFRS and are not necessarily indicative of operating costs, operating profit or cash flows presented under IFRS.
