/CNW/ - Laramide Resources Ltd. ("
Laramide
" or the "
Company
")
(TSX: LAM) (ASX: LAM) (OTCQX: LMRXF) is pleased to announce completion of the initial diamond
drilling phase of the project ramp-up at its 100% owned NRC licensed Crownpoint-Churchrock
Uranium Project, near Gallup,
New Mexico, USA
("Crownpoint"). The diamond drill program, having
a total drilled length of 6,030 feet (1,838 meters) was comprised of seven drill holes located in areas
of uranium mineralization within Section 17, Township 16 North South, Range 16 West and located
along the boundary between Section 17 and Section 8. Three of these drill holes were "twin holes"
drilled within 20 feet (ft) of historic drill holes designed to confirm the stratigraphic position of
uranium mineralization, the relative thicknesses of mineralized intervals, the range of uranium grades
that were encountered in the historical drill holes and to provide drill core for chemical assays and
radiometric equilibrium analysis. The project is being managed by NuFuels, Inc., a wholly owned
subsidiary of Laramide Resources Ltd., which oversees Laramide's uranium asset portfolio in
the
United States
. As reported on
December 13, 2022
, and
January 23, 2023
, Laramide has appointed
SLR International Corporation ("SLR") of Denver, Colorado, to complete an NI 43-101 Preliminary
Economic Assessment ("PEA") with respect to the Churchrock Uranium Project (the "Project").

Ltd.)
Crownpoint consists of two discrete ISR-amenable deposits, Crownpoint and Churchrock, covered
by a single NRC license (SUA-1580). The PEA envisions that uranium will be mined by in situ
recovery (ISR) methods at only the Churchrock location and recovered in a proposed new
processing facility at the nearby
Crownpoint
location where significant project infrastructure already
exists. When completed in Q2 2023, the PEA will provide estimates of project economics based on
ISR mining of estimated mineral resources in Section 8 of the Churchrock NRC license area,
recovery factors, and life-of-project permitting, capital, operating, and reclamation cost estimates for
the mine area and the proposed
Crownpoint
processing facility.
The recent drilling conducted at Churchrock confirmed that historical drilling results are suitable for
resource estimations and agreed with previous studies showing there is low risk of depletion of
chemical uranium compared to radiometric uranium in the Churchrock mineralization, and will also
provide core for the test work necessary to obtain the New Mexico Aquifer Discharge Permit, the
final material permit needed for the project. Upon completion of drilling, each drill hole on the Project
was logged with a suite of geophysical tools including natural-gamma, spontaneous potential (SP),
and resistivity. All downhole logging was conducted by COLOG. Natural gamma logging is an
industry-standard procedure for estimating equivalent uranium grades and was utilized in historic drill
campaigns at Churchrock. Recovered drill core from the new holes was logged by project geologists
for lithology and mineralization, and one-half splits were collected for direct geochemical analysis of
uranium at Energy Laboratories, Inc. in Casper, Wyoming.
The results of the recent drilling confirmed the location and tenor of uranium roll fronts at Churchrock
(Figure 2). Chemical assays of uranium were compared to recent and historic gamma-equivalent
uranium grades from the Westwater Canyon B Sand (Jmw B) which was the primary target of the
2022 drill program and the primary mineralized sand targeted for ISR mining in Section 8 are shown
in Table 1. Chemical assays show an average thickness of 18.3 ft of 0.061% U

, compared to a
gamma-equivalent average thickness of 21.7 ft at 0.045% eU

Comparing historic twin holes
against holes completed in 2022 for equivalent grade (Table 2) showed an average thickness of
15.8 ft at 0.039% eU

compared to an average thickness of 20.5 ft at 0.046% U

from the
nearby historic holes. Both comparisons favorably validate that the historic drilling results are
suitable for declaring Mineral Resources.
From a grade thickness standpoint (grade thickness ("GT") defined as the grade multiplied by the
thickness of a mineralized intercept), all of the holes tabled below had GT's in excess of 0.3 %-ft
which is the minimum GT considered typical for mining by ISR.

Mineralized core from the recently completed program will also be used by NuFuels in a planned
laboratory-scale program carried out jointly with the US Department of Energy's
Los Alamos, New
Mexico
laboratories to demonstrate the capacity to restore groundwater geochemical conditions to
levels that existed prior to uranium recovery through the application of ISR methods. The objectives
for this program are as follows:
Complete a bench level testing program in support of the New Mexico State discharge permit
application;
Replicate the in-situ uranium chemistry and recovery characteristics at the laboratory scale;
Determine ISR mining reaction kinetics data specific to the ore body;
Duplicate expected reverse osmosis (RO) restoration chemistry characteristics and evaluate the
results;
Examine uranium and other trace element concentrations after simulated reverse osmosis
treatment and sulfide treatment;
Record pH and clay mineralogy of the (laboratory) leached samples; and,
Examine uranium and other potential trace metals concentrations for rebound during a post
restoration stability period.
Background on Churchrock properties:
The Churchrock properties within the Crownpoint Project consist of 4,053 acres within the historic
Grants Mining District in McKinley County,
New Mexico
. The Project is a compilation of significant
historical work completed by major mining and energy companies. The United States Nuclear
Regulatory Commission (NRC) has granted a license for production of uranium from sections of
Churchrock.
In 2017, SLR formerly known as Roscoe Postle Associates Inc. ("RPA") produced a Technical
Report on the Churchrock properties from drill hole data available as of September 2017. Data from
previous operators was consolidated and digitized resulting in a database of 1,667 drill holes totaling
1,841,545 ft of drilling. Using a 0.5 ft-% eU
3
O
8
Grade Thickness (GT) cut-off, the Inferred Mineral
Resource totals 33.9 million short tons (Mst) at an average grade of 0.08% eU
3
O
8
for a contained
metal content of 50.8 million pounds (Mlb) U

O

.
The current Mineral Resource is classified as Inferred based on the historic nature of the drilling data
and drill hole density along mineralized trends contained within the sandstone units of the Brushy
Basin and Westwater Canyon Members of the Morrison Formation.
A discharge permit for the underground injection and control associated with the Project will be
required by New Mexico Water Quality Control Commission rules. Test work in support of this
discharge permit is described above.
