GFG Receives Positive Initial Metallurgical Results from
Rattlesnake Hills Gold Project Partner Group 11 Technologies
March 15, 2022, Saskatoon, Saskatchewan, Canada: GFG Resources Inc. (TSXV: GFG )
(OTCQB: GFGSF) (“GFG” or the “Company”) is pleased to report that it has received positive
metallurgical results from the Rattlesnake Hills Gold Project (“RSH Project”) located in Wyoming
U.S. from its option partner, Group 11 Technologies Inc. (“Group 11”), (see news release: “GFG
Signs Option Agreement with Group 11 Technologies to Advance the Rattlesnake Hills Gold
Project with Disruptive Technology ”). Provided below are the first test results in the process to
develop In-situ Recovery ( “ISR”) technology for gold mining using EnviroMetal Technologies
Inc. (“EnviroMetal”) (CNSX: ETI) non-cyanide and environmentally friendly leaching solution.
The gold recovery tests from uncrushed half -core samples demonstrated recoveries ranging from
15.9% to 77.5%, averaging 48.2% while the bottle roll testing of crushed material returned gold
recoveries ranging from 38.3% to 89.5%, averaging 61.4%.
“These initial results have exceeded our and Group 11’s expectations and this is an exciting
development for our shareholders, stakeholders and the gold mining industry as a whole,” stated
Brian Skanderbeg, President and CEO of GFG . “We look forward to the next phase of testing as
they continue along the path of proving and adapting ISR technology to gold mining.”
Dr. Dennis Stover, Group 11 and enCore Energy Corps’ Chief Technical Officer and co-discoverer
of the in-situ recovery process in the uranium sector said: “Group 11 is very pleased with the initial
tests which show ed strong results to extract gold from the existing core sample s with an
environmentally-friendly solvent. This first step will provide the basis for future tests to be
conducted on the use of the lixiviant in combination with ISR technology. Group 11 is working to
create new environmentally-friendly options to extract gold and other metals through less invasive
ISR extraction which is in widespread use in the uranium sector.”
LIVE WEBCAST – MARCH 17, 2022 11 AM ET
Group 11 and their partners will host a webcast on Thursday, March 17 at 11:00 am Eastern Time
(8:00 am Pacific Time) to discuss the results of the Phase 1 tests, next steps and to answer any
questions from shareholders. Shareholders, analysts, investors, and media are invited to join the
live webcast by registering using the link below. A replay of the webcast will be available

SAMPLE DESCRIPTION
The Phase 1 program was designed to conduct staged metallurgical tests on core samples from
across a broad range of mineralization and grade profiles from previously drilled core from the
RSH Project. The objective was to assess the amenability and recovery rates for extracting gold
from the core using the eco-friendly water-based solution.
Group 11 selected 17 half-core and 22 composite core chip samples from the RSH Project with the
objective of evaluating gold recovery and leach kinetics to provide baseline data for future studies
focused on in-situ leaching using EnviroMetal’s environmentally superior leach chemistry.

UNCRUSHED SAMPLE TESTING
The half core samples were leached whole and uncrushed in EnviroMetal’s solution at 28% - 45%
pulp density for 22 to 92 days to investigate gold recovery for ISR application. Gold recoveries
ranged from 15.9% to 77.5%, averaging 48.2%. These samples were tested whole without crushing
to more closely emulate expected results from an ISR environment.

BOTTLE ROLL TESTING
The rock samples were crushed to - 2.5 mm and tested via bottle roll methodology with
EnviroMetal’s solution at 30% pulp density for 9 to 28 days at a neutral pH to investigate gold
recovery. Gold recoveries ranged from 38.3% to 89.5%, averaging 61.4%. Leaching with the bottle
roll on crushed material provided faster kinetics and higher recoveries, as would be expected, due
to the increased surface area exposed to the solution.

Recovery Curves of Bottle Roll Testing
Although not directly comparable due to significantly different testing parameters, these new bottle
roll test results compare favorably with traditional bottle roll results from testing conducted in 2009
by Resource Development Inc. (“RDI”) for the RSH Project. The RDI testing utilized cyanide with
1g/l of NaCN, a pH of 11, 40% solids, 72-hour leaching time and a very fine grain size of 80% less
than .074mm. Gold recoveries from these historic cyanide bottle roll tests ranged from 13.7% to
65.4%, averaging 43.4% from 15 composite drill core samples.
Next Steps
With successful initial test work that exceeded recovery rate expectations, Group 11 will proceed
to conduct further ISR analyses and data review related to the RSH Project. The technical review
will further assess the amenability and recovery rates for extracting gold using the eco -friendly
water-based solution. Next steps to advance the RSH Project may include additional laboratory
tests, additional drill tests and related project permitting.

from the 17 half core leach tests were analyzed by MSALABS, an independent lab based in
Langley, British Columbia.
About The Rattlesnake Hills Gold Project and Joint Venture
The RSH Project is a district -scale gold exploration project located in central Wyoming ,
approximately 100 kilometres southwest of Casper. Geologically, the RSH Project is centrally
located within a roughly 1,500-kilometre-long belt of alkalic intrusive complexes that occur along
the eastern side of the Rocky Mountains from Montana to New Mex ico, several of which are
associated with multiple gold deposits. The RSH Project has approximately 100,000 metres of
historic drilling which has outlined three significant zones of precious metal mineralization that are
associated with Eocene age alkalic intrusions at North Stock, Antelope Basin and Blackjack. Both
the North Stock and Antelope Basin deposits are near surface, oxidized, disseminated and
expandable. At both deposits, gold occurs under relatively accessible topography, an important
consideration for ISR development. In addition to the outlined zones of mineralization, the district
remains highly prospective with several kilometre-scale greenfield targets that have never been
drill tested.
Under the terms of the option and earn-in agreement, Group 11 has the right to acquire, in multiple
stages, up to 70% of the RSH Project by completing a series of exploration and development
expenditures and making staged cash and equity payments to GFG (see news release: “GFG Signs
Option Agreement with Group 11 Technologies to Advance the Rattlesnake Hills Gold Project with
Disruptive Technology”).
About Group 11 Technologies Inc.
Group 11 Technologies Inc. is led by a group of technical pioneers and experts in the development
and application of ISR with significant experience operating in the United States. Group 11’s goal
is to combine ISR, a non-invasive extraction technology, with an environmentally friendly water-
based chemistry to recover gold and other metals, providing an alternative development path to
conventional open pit and underground mineral extraction. The combination of ISR technology and
environmentally friendly water -based chemistry to recover gold and other metals provides a
promising alternative solution to conventional open pit and underground mineral extrac tion. The
goal of advancing sustainable extraction considers growing concerns surrounding water use and
discharge, carbon footprint, energy consumption, community stakeholders and workplace safety
while addressing a growing global need for metals in our daily lives.
About GFG Resources Inc.
GFG is a North American precious metals exploration company focused on district scale gold
projects in tier one mining jurisdictions, Ontario and Wyoming. In Ontario, the Company operates
three gold projects, each la rge and highly prospective gold properties within the prolific gold
district of Timmins, Ontario, Canada. The projects have similar geological settings that host most
of the gold deposits found in the Timmins Gold Camp which have produced over 70 million ounces
of gold. The Company also owns 100% of the Rattlesnake Hills Gold Project, a district scale gold
exploration project located approximately 100 kilometres southwest of Casper, Wyoming, U.S. In
Wyoming, the Company has partnered with Group 11 through an option and earn-in agreement to
advance the Company’s Rattlesnake Hills Gold Project with a technology that could revolutionize
the gold mining industry.
