Foran Mining Corp. Announces 70% Increase in Indicated Resources at McIlvenna Bay

Deposit Remains Open and Exploration Planning Underway for 2022

VANCOUVER, Oct. 14, 2021 - Foran Mining Corp. (TSXV: FOM) ("Foran" or the "Company") is pleased to announce an updated mineral resource estimate (the "2021 Resource Estimate") for the Company's 100%-owned McIlvenna Bay Deposit ("McIlvenna Bay" or the "Deposit") located in east-central Saskatchewan. The 2021 Resource Estimate outlines significant changes to the resource at McIlvenna Bay compared to the previous resource estimate published in 2019, with over 25,000m of infill and expansion drilling in 36 holes were completed since the prior estimate. To date, the Deposit has been defined by approximately 152,000m of drilling within 285 holes.

Highlights include:

• Indicated resources increased by 70% to 39.1 million tonnes ("Mt") from 23.0Mt (see Table 1):
• • Indicated resources now grade 1.20% copper ("Cu"), 2.16% zinc ("Zn"), 0.41 g/t gold ("Au") and 14 g/t silver ("Ag") or 2.04% copper equivalent ("CuEq")
  • Indicated resources contain 1.03 billion pounds ("Blbs") Cu, 1.9Blbs Zn, 510 thousand ounces ("koz") Au and 18.1 million ounces ("Moz") Ag
• Inferred resources total 5.0Mt at 0.94% Cu, 2.56% Zn, 0.17% Pb, 0.27 g/t Au and 16 g/t Ag (1.77% CuEq)
• • Inferred resources contain 105 million pounds ("Mlbs") Cu, 284Mlbs Zn, 40koz Au and 2.6Moz Ag
• Significant Increase in Indicated Contained Metal
• • 74% increase in contained Cu, 21% increased in contained Zn, 58% increase in contained Au and 47% increase in contained Ag relative to the 2019 Resource estimate
• Mineralization Starts Near Surface and Remains Open at Depth
• • Mineralization begins ~25m below surface and extends down-plunge approximately 2km, where it remains open in all directions
• Feasibility Study Remains on Track and 2022 Regional Exploration Campaign Planning Underway
• • The updated resource estimate and increased indicated resources will underpin the coming feasibility study and could support potential mine life extensions

Dan Myerson, CEO & Executive Chairman, commented "As demonstrated by the incredible success of our 2021 infill program, McIlvenna Bay has now proved itself to be a high-quality, large and cohesive deposit, that will act as the first mining operation for our planned and scalable centralized processing facility at the Hanson Lake District. The significant increase in indicated resources from our ~25,000m program in 2021 is a testament to the skill and efforts of our world-class exploration team and showcases the continuous nature of the deposit, which remains open and has the potential to grow. We are now integrating the data from this resource estimate into our coming feasibility study and are planning for an aggressive and exciting exploration program in 2022."

Additional Details

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 ("NI43-101"). The 2021 Resource Estimate will be used to support the upcoming feasibility study ("Feasibility Study"). The 2021 Resource Estimate is summarized in Table 1. See below for additional information with respect to Qualified Person, Estimation Methodology and Parameters.

(US$60/t NSR cut-off)

The 2021 Resource Estimate builds on and supersedes the previous comprehensive National Instrument 43-101 ("NI 43-101") mineral resource estimate for the Deposit which was announced by the Company on May 28, 2019 (the "2019 Resource"). The 2021 Resource Estimate 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.

Mineralization

The 2021 Resource Estimate includes several zones and two distinct styles of mineralization, typical of volcanic-hosted massive sulphide ("VHMS") deposits:

• massive to semi-massive sulphide mineralization in the Main Lens and Lens 3
• stockwork-style sulphide mineralization in the Copper Stockwork Zone ("CSZ") that directly underlies the Main Lens;
• two other small lenses of stockwork-style mineralization occur in the Deposit:
• • the Stringer Zone, which is located between the Main Lens and Lens 3
  • the Copper Stockwork Footwall Zone ("CSFWZ") which occurs as a separate lens underneath the CSZ for approximately 150m of strike length which could represent a fault offset and repetition of the Main Lens and CSZ.

The Main Lens at McIlvenna Bay is a large massive to semi-massive sulphide horizon containing a metal zonation consisting of Cu-Au-rich material near the upper plunge line of the Deposit which transitions down dip into a more Zn-Ag-dominant massive sulphide. The Main Lens massive sulphide is a continuous mineralized horizon which varies from 0.1 to 18.0m in true thickness and averages 3.5m overall, with a strike length of 1,850m (Figure 5).

The CSZ is a zone of stockwork style copper-rich mineralization that directly underlies and is in contact with the massive sulphide and is interpreted to represent the feeder zone to the massive sulphide system. The CSZ varies from 0.3 to 26m in true thickness with an average thickness of 12.0m. The Main Lens 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 Deposit plunges at approximately 45 degrees from surface for a down plunge length of approximately 2,000m (Figure 6).

Lens 3 sits approximately 10 to 30m in the hanging wall above the Main Lens and demonstrates the presence of stacked sulphide lenses in the Deposit. This lens has been traced intermittently along a strike length of 1,600m and plunges parallel to the underlying Main Lens and CSZ. The lens ranges in thickness from 0.1 to 8.0m and averages 2.0m in true thickness. The Stringer Zone is a narrow intermittent lens of stringer-style sulphide that occurs sporadically between the Main Lens and Lens 3 through the Deposit. The zone has a strike length of 850m and averages 4.5m in true thickness through the deposit.

The CSFWZ is a separate lens that underlies the CSZ and has been intersected in nine drill holes over approximately 150m of strike length in the up-dip, central part of the Deposit. The lens varies in thickness from 0.3 to 38m with an average thickness of 30m. The CSFWZ dominantly consists of stockwork style copper-rich mineralization similar to the CSZ, although in several holes, narrow massive sulphide was also intersected at the top of the interval. It is possible that the CSFWZ represents a fault offset and repetition of the Main Lens and CSZ, but further drilling is required to prove the relationship of this lens to the rest of the Deposit.

Contained Metal

There has been substantial growth in the McIlvenna Bay resource since the 2019 Resource Estimate was issued including a 74% increase in contained Cu, 21% in contained Zn, 47% increase in contained Ag and 58% increase in contained Au. See Table 2 below outlining the contained metal in the 2021 Resource Estimate.

Qualified Persons

The 2021 Resource Estimate meets the guidelines as set out in NI43-101 and was completed and verified by Micon, a global geological and mining consultancy. The 2021 Resource Estimate was verified by Mr. William J. Lewis, P.Geo. Mr. Lewis is a Qualified Person as defined in NI43-101 and has consented to applicable disclosure contained herein regarding the 2021 Resource Estimate.

Mr. Roger March, P. Geo., Senior Geoscientist for Foran, is the Qualified Person for all technical information in this news release, excluding the 2021 Resource Estimate. Mr. March has reviewed and approved the technical information in this release.

Estimation Methodology and Parameters

The 2021 Resource Estimate update included a re-interpretation of the mineralized envelopes in the Deposit following the incorporation of over 25,000m of diamond drilling completed since the 2019 Resource. The 2021 Resource Estimate was carried out using a block model constrained by 3D wireframes of the mineralized zones. Values for Cu, Zn, Au, Ag, and Pb were interpolated into the blocks using Ordinary Kriging, with validation estimates using ID² and nearest-neighbour performed to confirm results. Block size was 10m wide (east-west) x 2m across (north-south) x 10m high. The models were constructed using Leapfrog Edge software. The 2021 Resource Estimate has an effective date of September 6, 2021.

The 2021 Resource Estimate is based entirely on diamond drilling data. The database contained records for 285 diamond drillholes (including nine short geotech holes) of which 240 intersect the deposit, with a total of 5,652 assay intervals. Top cuts were applied to composites as required. A 1.0m composite length was used for all domains at McIlvenna Bay (respecting the original mean sample length), within the domains <0.5m end length samples were distributed equally.

Implicit modelling was used to dynamically generate wireframes using the mineralized intercepts as defined by the interpretation for each domain on 25m cross sections. In constructing these models, a 0.5% Cu cut-off was used for compositing the intercepts in the interpretation of the CSZ, while the logged geological intervals were used to constrain the intercept lengths for the massive and semi-massive sulphide zones. The $60/t NSR cut-off was derived by Micon based on comparable projects in North America, taking into account provisions for milling, G&A, and direct mining costs (i.e. no development). Density was interpolated into each block using ID0 (moving average) based on specific gravity measurements collected from core samples.

The Mineral Resources were classified using the following criteria:

• Resources were classified as indicated in the core of the Deposit, where the nominal drill hole spacing is 100m within the CSZ and 120m in the massive sulphide lens. The classification reflects not only the drill spacing, but the confidence level in the continuity of the grade and the geometry of the Deposit.
• Resources classified as inferred were defined by blocks which were estimated with less stringent requirements within search ellipses defined for each domain to a maximum distance of 250 m in both the massive and semi-massive sulphide and stockwork bodies.

In Micon's opinion, the Mineral Resources are classified in a manner that is consistent the May 10, 2014 CIM Definition Standards for Mineral Resources and Mineral Reserves. Mineral resources do not have demonstrated economic viability. In Micon's opinion, there are currently no relevant factors or issues that effect the 2021 Resource Estimate, however, there is no guarantee that the Deposit will be placed into production.

Quality Assurance and Quality Control

For drilling conducted by Foran and its consultants since 2011, an independent QA/QC protocol, consisting of blanks, standards, and duplicates introduced into the sample stream for each batch of samples processed by the laboratory and the results of the assaying of the QA/QC material included in each batch are tracked to ensure the integrity of the assay data. Sample analysis was performed by TSL Laboratories Ltd. ("TSL") in Saskatoon, Saskatchewan. TSL is a CAN-P-1579, CAN-P-4E (ISO/IEC 17025:2005) accredited laboratory and independent of Foran.

Micon reviewed the QA/QC reports from these programs and noted that there were no issues that arose which would affect confidence with the assay data. Micon considers the sampling method appropriate for the deposit type, adequate security measures were maintained, and samples should be representative of the mineralization.
