VANCOUVER, BC, Nov. 30, 2023 /PRNewswire/ - Freeman Gold Corp. (TSXV: FMAN) (OTCQX: FMANF) (FSE: 3WU) ("Freeman" or the "Company") is pleased to announce that it has filed a National Instrument ("NI") 43-101 Technical Report entitled "Lemhi Gold Project, NI 43-101 Technical Report and Preliminary Economic Assessment, Idaho, United States" dated effective of October 13, 2023 (the "Report") on SEDAR+ at www.sedarplus.ca. The Report is with respect to Freeman's Preliminary Economic Assessment ("PEA") on the Lemhi Gold Project, Idaho, USA, the results of which were announced in an October 13, 2023 news release. The PEA outlines a high-grade, low-cost, open pit operation with an average annual production of 80,100 ounces of gold ("Au") in the first eight years. The production strategy outlined in the PEA consists of a phased development with an increase in throughput during the fifth year of operation, with a flowsheet utilizing a carbon-in-leach ("CIL") processing facility. The objective of the study has been to maximize the value of Lemhi, while minimizing the footprint and environmental impact of the facility.

Lemhi PEA Highlights:

• After-tax NPV(5%) of US$212.4 million and IRR of 22.8% using a base case gold price of US$1,750/oz.
• After-tax NPV (5%) of US$ 345.7 million and IRR of 31.9% using spot gold price of $2,042.60 US$/oz.
• Average annual gold production of 75,900 oz Au for a total life-of-mine ("LOM") 11.2 years payable output of 851,900 oz Au.
• LOM cash costs of US$809/oz Au and all-in sustaining cash costs ("AISC") of US$957/oz Au.
• Initial CAPEX of US$190 million.

Production Profile & Economic Analysis

The results of the PEA demonstrate Lemhi has the potential to become a profitable, low-cost gold producer. With an average annual gold production of 75,900 oz Au over the 11.2-year LOM, Lemhi has a life of mine payable output of 851,900 oz Au and average annual gold production of 80,100 oz Au in the first eight years of production.

With an average operating cost of US$21.53/t milled over the LOM, the operation has cash costs of US$809/oz Au and AISC of US$957/oz Au. The project has an initial capital cost of US$190 million.

The economic analysis was performed assuming a 5% discount rate. Cash flows have been discounted to the start of construction, assuming that the project execution decision will be taken, and major project financing will be carried out at this time.

The preliminary economic assessment is preliminary in nature, that it 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 preliminary economic assessment will be realized.

On a post-tax basis, the NPV discounted at 5% is US$212.4 million; the IRR is 22.8%; and payback period is 3.6 years. A summary of the post-tax project economics is shown graphically in Figure 2 and listed in Table 2.

Mining and Metallurgy

The deposit is amenable to open pit mining practices. Mine production planning is based on conventional drill/blast/load/haul open pit mining methods suited for the project location and local site requirements. The open pit activities are designed for approximately two years of construction followed by 12 years of operations. The PEA mine production plan estimates a total LOM mill feed of 31,128 kt of mineralized rock at an average feed grade of 0.88 g/t Au. Based on the current mineralized rock extents, the pit design results in a 3.9 waste to mineralize rock ratio.

Pit designs are configured on 5 m bench heights, with minimum 8 m wide berms placed every four benches, or quadruple benching. Slopes of 25 degree are applied in the thin overburden layer above the deposit bedrock. Since there has been no geotechnical test work or analysis completed on the bedrock, the applied bench face and inter-ramp angles, 70-75 degrees and 50-55 degrees respectively, are scoping level assumptions based only on the rock type and overall depth of the open pit.

Resource from the open pit will report to a ROM pad and primary crusher directly northeast of the pit rim. The mill will be fed with material from the pits at an average rate of 2.5 Mt/a (6.8 kt/d), increasing to 3.0 Mt/a (8.2 kt/d) after four years of operation. Resources mined in excess of mill feed targets will be stored in a low grade stockpile directly south of the ROM pad, and east of the open pit. This stockpile is planned to be completely reclaimed to the mill at the end of the mine life. Waste rock will be placed in one of two facilities, each planned as a comingled facility with the processed tailings.

The mine production schedule is summarized in Figure 3 below. The overall site layout is shown in Figure 4.

 

A number of metallurgical test programs have been completed on the Lemhi Gold Project since 1994. A summary of the test programs is presented in Table 3.

Table 3- Summary of Metallurgical Test Programs

Year	Laboratory	Description
1994	Kappes Cassiday, Reno	Phase 1 - column leach, bottle roll tests on 7 composites
1995	Kappes Cassiday, Reno	Phase 2 - column leach, bottle roll tests on 1 composite
1995	Kappes Cassiday, Reno	Phase 3 - column leach, bottle roll tests on 2 composites
2021	SGS, Vancouver	11 samples tested in 2 phases; included gravity, bottle roll, flotation, comminution. Additional phase of variability testing - 26 samples Solid/Liquid separation
2023	Base Met, Kamloops	comminution on 5 samples gravity and leach testing on 2 master composites CN detox and dewatering testing

The process flowsheet for the Lemhi Gold project was selected based on the metallurgical test work results and flowsheet trade off study and was tailored to support the ramp-up of the plant throughput in Year 5 and a production profile over the life of mine. The unit operations selected are standard technologies used in gold processing plants. The proposed flowsheet uses conventional equipment for the following circuits which include crushing/grinding, leaching/carbon adsorption, carbon desorption/electrowinning/refining and cyanide destruction/wet tailings deposition.

The process design is comprised of the following circuits: primary crushing of run-of-mine (ROM) material; semi-autogenous grinding (SAG) mill followed by ball mill with cyclone classification; leach and carbon-in-leach adsorption; acid washing and elution of loaded carbon; electrowinning and smelting to produce doré; carbon regeneration; and cyanide destruction and wet tailings disposal.

Capital & Operating Costs

The capital cost estimate conforms to Class 5 guidelines for a PEA-level estimate accuracy according to the Association for the Advancement of Cost Engineering International (AACE International). The capital cost estimate was developed in Q2 2023 United States dollars based on Ausenco's in-house database of projects and studies, budget pricing for equipment, as well as experience from similar operations.

The estimate includes open pit mining, processing, on-site infrastructure, tailings and waste rock facilities, off-site infrastructure, project indirect costs, project delivery, Owner's costs, and contingency. The capital cost summary is presented in Table 4. The total initial capital cost for the Lemhi Project is US$190.2 M; and life-of-mine sustaining costs are US$101.2 M. The cost of expansion in fifth year is estimated at US$7.6 M. Closure costs are estimated at US$29.9 M, with salvage credits of US$12.0 M.

The operating cost estimates was developed from first principles and applied to the mine production schedule. Productivity and cost inputs are derived from historical reference data. and includes mining, processing, maintenance, power, and general and administration (G&A) costs. Table 5 provides a summary of the project operating costs.

The overall life-of-mine operating cost is US$670.3 M over 11.2 years, or an average of US$21.53/t of material milled in a typical year.
