Stratabound Announces Positive PEA for Fremont Gold Project; 11 Year Mine Life with Average Annual Production of 118,000 Gold Ounces at an AISC of US$1,082/oz and an After-Tax NPV5% of US$210M

Toronto, Ontario--(Newsfile Corp. - February 15, 2023) - Stratabound Minerals Corp. (TSXV: SB) ("Stratabound" or the "Company") is pleased to announce positive results from the independent Preliminary Economic Assessment ("PEA") for its 100% owned Fremont Gold Project (the "Project") located in the Mother Lode Gold Belt, north central California.

Highlights:

• After-tax net present value ("NPV") (discount rate 5%) of US$210M, internal rate of return ("IRR") of 21% and payback of 4.2 years at a gold price of US$1,750/oz

• 11-year mine life producing 1,303,000 ounces of gold

• Average annual gold production of 118,000 ounces over life of mine ("LOM"), with a peak production of 157,000 ounces in the 4^th year

• Average cash cost of US$872/oz and all-in sustaining cost ("AISC") of US$1,082/oz gold

• Initial Capital Expenditure of US$203M

• Annual process plant rate of 2.19 M tonnes at an average feed grade of 2.4 g/t Au and average overall gold recovery, including offsite processing, of 75.4%

The PEA is preliminary in nature, includes Inferred Mineral Resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as Mineral Reserves, and there is no certainty that the PEA will be realized. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability. There are no Mineral Reserves contained in the PEA.

P&E Mining Consultants Inc. ("P&E") were retained as an independent consultant and Qualified Persons in March 2022 to undertake a Mineral Resource Estimate ("MRE") and PEA on the Fremont Gold Project in accordance with National Instrument 43-101 ("NI 43-101"). Kappes, Cassiday & Associates ("KCA") was also engaged for the design and capital and operating costs for the process plant, heap leach facility and project infrastructure.

Kim Tyler, President and CEO of Stratabound, stated today, "This PEA provides a solid, conservative base case and a clear path forward with plenty of runway to build and improve upon. Only 35% of mineralized strike and two of four mineralized zones have been defined and evaluated to date. Most notably, the opportunity remains to expand the at-surface oxide/heap leach potential indicated by the 4-km long by 285-m wide 0.03 - 5.21 g/t (0.41 g/t average) gold-in-soil anomaly that covers the entire 4 km strike length, (See Feb. 23, 2022 Press release). Oxide Heap Leach is a conventional cost-efficient processing method already proven and functioning at Equinox Gold's successfully operating gold mines in California."

He further stated, "Stratabound is committed to safety, environmental and social responsibility foremost in this enterprise. Implementing the Railveyor™ system of bulk material transport at Fremont will substantially mitigate greenhouse gas emissions. The Railveyor™ is a relatively new, however proven, electric-powered, hybrid conveyor-rail system that will replace approximately 5 conventional diesel-powered haulage trucks in the underground-to-surface plant haulage configuration. Future studies will examine the use of the Railveyor™ in the pit configuration, as well as other electric green-equipment alternatives, automation and green technology that may be implemented as that sector continues to leap forward and become more cost-efficient.. The PEA further accounts for progressively backfilling the open pit and returning mine tails back underground as paste fill thereby minimizing the footprint and more swiftly restoring the land back to its original state. Foremost in consideration of future planning is not just simply reclamation, but enhancing the Property's natural repose and lasting value for the benefit of wildlife, the environment and community well beyond the end of mine life."

Project Description and Location

The Fremont Gold Project is 100% owned by Fremont Gold LLC, a wholly owned subsidiary of Stratabound Minerals Corp., and is located in Mariposa County, California approximately 241 km east of San Francisco in the southernmost portion of the prolific California Mother Lode Gold Belt. The Project lies within the Company's wholly owned 3,351-acre (13.56 km²) Fremont Property (the "Property"). The Property includes 100% of the mineral, surface and groundwater rights and features four gold mineralized zones and three former producing gold mines along 4-km of the Mother Lode Gold Belt. The PEA considers two of these zones, the Pine Tree/Josephine Deposit and the Queen Specimen Deposit, along 1.4-km of the 4-km total strike length. California State Highway 49 transects the Property from north to south and a 70 kV power transmission line traverses the Property.

Mineral Resource Estimate

The Fremont Gold Project Mineral Resource Estimate was prepared by P&E with an effective date of June 30, 2022 in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (CIM) Definition Standards on Mineral Resources and Reserves (2014) and Best Practices Guidelines (2019) (see press release of August 18, 2022).

Pit-constrained Mineral Resources are reported using a cut-off grade of 0.25 g/t Au for oxide material and 0.45 g/t Au for sulphide material. Out-of-Pit (underground) Mineral Resources are reported using a cut-off grade of 1.45 g/t Au. Underground Mineral Resources have been constrained within potentially mineable long-hole shapes based on block grade and continuity. Historical mining has been depleted from the updated Mineral Resource Estimate by assigning a zero-volume percentage block inclusion for known areas of mining and development.

The Fremont Gold Project MRE, including the Pine Tree-Josephine and Queen Specimen Deposits, comprise 1,163,000 ounces of gold in the Indicated classification and 2,024,000 ounces of gold in the Inferred classification. The MRE accounts for an aggregate of only 1.4-km of the entire 4-km Project strike length.

A summary of the MRE is provided in the following table. The economic assumptions used for the updated MRE are provided in the notes to the table.

Table 1: Summary of Mineral Resource Estimate

Table notes:

1. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
2. A gold price of US$1,700/oz was used.
3. A cut-off grade of 0.25 g/t Au for oxide material, 0.45 g/t Au for sulphide material and 1.45 g/t Au for underground material was used.
4. Pit-constrained Mineral Resources were determined to be potentially economic based on a mining cost of US$3/t mined, heap leach processing of US$9.16/t, flotation processing of US$10.02/t and G&A costs of US$2.50/t, with metallurgical recoveries of 85% by heap leach and 90% by flotation.
5. Out-of-Pit Mineral Resources were determined to be potentially economic with the longhole mining method based on an underground mining cost of US$40/t mined, processing of US$10.02/t and G&A costs of US$2.50/t, with a metallurgical recovery of 90%. Out-of-Pit grade blocks that did not demonstrate potentially mineable configurations were removed from the Resource Estimate.
6. The Inferred Mineral Resource in this estimate has a lower level of confidence that that applied to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of the Inferred Mineral Resource could be upgraded to an Indicated Mineral Resource with continued exploration.
7. Totals may not sum due to rounding.

Mining

Mining will begin with three small oxide starter pits and heap leach in year 1 concurrent with initial Pine Tree-Josephine open pit phase 1. The oxide heap leach pad is planned to be constructed within the tailings facility to minimize Project footprint and use a common liner.

The three-phased Pine Tree-Josephine open pit is planned for a production rate of 6,000 tonnes per day to provide low-cost production and generate early cash flow while the construction and development of the underground operation starts in year 2.

Upon completion of the Pine Tree-Josephine open pit in year 4, the Queen Specimen open pit is planned to be developed to supplement underground production to feed the process plant at a rate of 750kt per year. The open pits will be backfilled with waste rock after mining is completed. There will be opportunity for progressive reclamation over the life of the mine.

The Pine Tree-Josephine underground mine is planned for a production rate of 4,000 tonnes per day. The selected mining method is long-hole open stoping with both longitudinal retreat and transverse mining, depending on the vein thickness. Stopes will be filled with cemented paste backfill. Stope dimensions will average 10 metres in strike length and 30 metres in height, with a minimum thickness of 4 metres. Mineralized material will be extracted using a fleet of 10-tonne load-haul-dump units that will tip material down a broken material pass to a Railveyor™ system on a main haulage level. The Railveyor™ will transport material to the process plant via the portal and up a surface hillside.

Metallurgy and Mineral Processing

A total of 6,000 tpd of material will be treated in a process plant that consists of three-stage crushing, followed by a grinding circuit consisting of a primary ball mill. A gravity circuit will recover coarse gold from the plant feed, which then moves on to rougher flotation cells creating a sulphide concentrate containing the gold. The concentrate will be reground and fed to cleaner cells where the clean concentrate and gravity concentrate will be filtered and bagged for shipping to a roaster offsite.

For the first year of operation, a heap leach plant will be built to recover the gold in carbon from the heap leach pad that will be constructed in the tailings facility to minimize footprint and maximize use of liner construction.

The process plant is followed by a tailings filtration plant with a filter press to produce paste backfill to send underground and/or to produce dry stack tailings for surface storage.

The flotation plant gold recovery is estimated to average 92% gold to concentrate. At the roaster, 82% of the gold contained in concentrate is payable, including processing charges.

Infrastructure

Supporting infrastructure on site will include a laboratory, administration offices, a mine dry, warehouse, first aid office and truck maintenance shop.

In order to mine the Pine Tree-Josephine open pit, a short highway bypass is planned to be constructed.

Environment and Social

The Company continues to work with its environmental consultants to develop a plan for permitting the Project. The Company reports that its baseline environmental program is progressing well including biological studies, surface water and monitoring groundwater wells for routine sampling. Other planned evaluations for the permitting strategy will necessarily consider mine design, processing, and reclamation plan development.

The Fremont Project is located in Mariposa County on private land and, as such is subject to California Environmental Quality Assurance ("CEQA") process Surface Mining and Reclamation Act ("SMARA"). A Conditional Use Permit ("CUP") and approved closure plan is sought from the county following the completion of the Environmental Impact Report and Closure Plan acceptance. In addition to CUP and closure plan approval, the project will require permits and authorizations prior to construction and operation of the mine. Requests for these approvals will be submitted following the CUP and closure plan approval.

Meanwhile, Stratabound views this development in terms of its benefits to the California economy, as well as the local Mariposa community through re-invigorating California's mineral wealth under modern regulatory requirements and environmental awareness.

Next Steps

The results of the PEA indicate that the proposed Fremont Gold Project has technical and financial merit using the base case assumptions. It has also identified additional upside opportunities for oxide expansion and further Project optimization.

The Company expects to move forward with enhancing the Project through exploration and further drilling. The Company will also continue to generate additional drilling targets.

The Company expects to continue baseline environmental work and commence permitting activities which will include technical studies and surveys for the Project. The results of the studies, surveys and the engineering work completed for the PEA will be used to complete the application for the CUP. The public release of this PEA will greatly assist the Company in advancing its program of public and stakeholder engagement.
