VANCOUVER, BC, Nov. 30,
2023 /CNW/ - 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.
- Average gold recovery of 96.7%.
- High average mill head grade of 0.88 g/t Au.
- Average annual gold production of 80,100 oz Au in the first 8
years of production.
- Average mill throughput of 2.5 Mt/a (6.8 kt/d), increasing to
3.0 Mt/a (8.2 kt/d) after four years of operation.

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.

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
