Vancouver, British Columbia--(Newsfile Corp. - May 5, 2025) - Fuerte Metals Corporation (TSXV: FMT)
(OTCQB: FUEMF) ("
Fuerte
" or the "
Company
") is pleased to report results from the most recent five
holes of a diamond drilling program at its wholly-owned Cristina precious metals project in southwestern
Chihuahua State, Mexico.
Fuerte has now reported fifty holes totalling 13,754.7 metres of drilling from the current program. The
Cristina project consists of multiple outcropping quartz veins that are frequently greater than 10 metres in
width and extend for at least a five-kilometre strike length. Four parallel mineralized vein zones have
been mapped and sampled to date, with most of the existing mineral resource estimate at Cristina
contained within only one of the vein zones, the Guadalupe vein. These latest holes are all from the Los
Ingleses vein, northeast of the Guadalupe vein (Figure 1).
Drilling Highlights
Highlights of the holes reported here from Los Ingleses vein systems, include:
10.3 g/t AuEq over 2.4 m
estimated true width (ETW) (9.0 g/t Au, 90 g/t Ag, 0.02% Zn, 0.02% Pb
and 0.01% Cu) in hole
ACD-25-266
This 2.4 m wide intercept occurs within a broader mineralized zone measuring 2.6 g/t AuEq
over 10.5 m ETW (2.3 g/t Au, 22 g/t Ag, 0.02% Zn, 0.01 % Pb)
7.0 g/t AuEq over 1.4 m
estimated true width (ETW) (0.9 g/t Au, 91 g/t Ag, 7.65% Zn, 1.96% Pb
and 0.36% Cu) in hole
ACD-25-269 and
5.6 g/t AuEq over 3.6 m
estimated true width (ETW) (4.6 g/t Au, 12 g/t Ag, 1.32% Zn, 0.36% Pb
and 0.05% Cu), also in hole
ACD-25-269
These two higher-grade intercepts occur within a very wide mineralized zone measuring 0.7
g/t AuEq over 95.0 m ETW (0.4 g/t Au, 6 g/t Ag, 0.31 % Zn, 0.11 % Pb, 0.04% Cu)
Tim Warman, Fuerte's CEO, commented: "Almost every hole drilled to date on the Los Ingleses vein
system has encountered very wide, lower-grade intercepts with the widest intercept within 50-100 m of
surface, making them excellent candidates for open pit mining. These wider intercepts typically host one
or more narrower, high-grade zones that are in a gold rich area and likely continue at depth. Only a
fraction of the Los Ingleses vein system has been drill tested for inclusion in a resource level evaluation.
With fifty holes now completed in the current program, our focus has shifted to incorporating the data
collected into an improved and expanded geologic model in preparation for the mineral resource update
planned for later this year. The new resource estimate will incorporate both near-surface open pit
mineralization as well as high-grade zones for underground mining."
Geology and Context of Results
Hole ACD25-266 (Figures 2 & 3) discovered shallow high-grade gold and extended the high-
grade in drill hole ACD24-247 (7.1 g/t AuEq over 2.8 m; 1.9 g/t Au, 67 g/t Ag, 6.81% Zn, 1.06% Pb
and 0.42% Cu) an additional 50 meters at depth with both intercepts open at depth.
Hole ACD25-267 (Figures 2 &4) cut a wide lower-grade zone within 50 m of the surface. This is
the shallowest drill hole of a three hole fan on this section, expanding the Los Ingleses vein zone
further to the west. These intercepts are at the top of a large mineralized intrusive with shallow
open-pit potential.
Hole ACD25-268 (Figures 2 & 4) expands and adds continuity to the low-grade cut in the drill hole
above this hole (ACD25-267) and each low-grade zone contains a narrow high-grade vein. This
hole suggest that the grade improves with depth and the lower low-grade intercept crossed into a
unique felsic intrusive.
Hole ACD25-269 (Figures 2 & 4) expands the low-grade and high- grade veins at depth with both
the grade and volume of the mineralization increasing substantially. This mineralization is almost
entirely within a unique felsic intrusive with indications of porphyry-style mineralization and remains
open a depth. These results support the potential for a shallow open pit mining and may be part of
a large intrusive style deposit.
Hole ACD25-270 (Figures 2 & 5) expands low grade and narrow high grade further to the west
also within the unique felsic intrusive. This is the western-most drill hole at Los Ingleses and the
mineralization remains open to the west and at depth.
The fifty holes completed in this most recent campaign have successfully defined a series of continuous
higher-grade zones extending over several hundred vertical metres within the main Guadalupe vein, and
now within the Los Ingleses and Mexico Libre vein systems. Only 500 metres of the Los Ingleses multi-
kilometre vein has now been drill tested and the vein shows continuity in both high-grade and low-grade
veining with similar results and potential to that seen at Mexico Libre. These higher-grade zones remain
open along strike and at depth.
The Cristina deposit is an epithermal to mesothermal vein system where the mineralisation is
predominantly gold and silver, with lesser base metal values. At least four known major parallel vein
zones trend east-west to northeast-southwest and are hosted in an andesitic volcanic sequence which
forms part of the Lower Volcanic Sequence of the Sierra Madre Occidental range. The andesites and
related flows and breccias are cut locally by dacitic intrusions, and the entire sequence is in turn cut by
andesitic and hornblende-plagioclase porphyry following fault trends. In some areas the veins are
covered by post-mineral rhyolite of the Upper Volcanic Sequence.

Gold equivalent formula: AuEq = Au + 0.014*Ag + 0.480*Zn + 0.351*Pb + 1.246*Cu (See details under AuEq Calculation section of this release).
The goal of targeting the higher-grade zones within the main Guadalupe Vein, as well as other high-
grade veins in the area, is to both increase the size and the grade of the resource and demonstrate the
underground resource potential at Cristina. The current, primarily open-pit mineral resource estimate
comprises:
Indicated resources of 17.5 Mt at 0.51 g/t gold, 33.8 g/t silver, 0.47% zinc, 0.19% lead and 0.04%
copper (1.32 g/t AuEq grade), for a contained 747,000 gold-equivalent ounces.
Inferred resources of 19.0 Mt at 0.51 g/t gold, 27.5 g/t silver, 0.50% zinc, 0.19% lead and 0.05%
copper (1.26 g/t AuEq grade), for a contained 772,000 gold-equivalent ounces.
Mineral Resources are not Mineral Reserves and do not have demonstrated economic viability.
AuEq Calculation
Gold-equivalent values (AuEq) were calculated using USD metal prices of $1,700/oz gold, $23.61/oz
silver, $0.94/lb lead, $1.32/lb zinc, and $3.78/lb copper; metal recoveries of 92.9% for gold, 95.0% for
silver, 80.5% for lead, 86.9% for zinc and 71.3% for copper; and payability factors as described in Table
14.12 of the 2023 Cristina Technical Report.
The formula incorporating these factors is: AuEq = Au + 0.014*Ag + 0.480*Zn + 0.351*Pb + 1.246*Cu
AuEq calculations are reported for illustrative purposes only.
Quality Assurance and Quality Control Procedures
Drill core at the Cristina project is predominately HQ size with a diameter of 63.5 mm. Drill core samples
are generally 1.50 m long along the core axis with allowance for shorter or longer intervals if required to
suit geological constraints. After logging intervals are identified to be sampled, the core is cut and one
half is submitted for assay. Sample QA/QC measures include unmarked certified reference materials,
blanks, and field duplicates are inserted into the sample sequence and make up approximately 5% of
the samples submitted to the laboratory for each drill hole. Samples are transported to lab facilities in
Durango or Hermosillo Mexico, for sample preparation. Sample analysis is carried out by ALS Labs,
with fire assay, including over limits fire assay re-analysis, and multi-element analysis completed in North
Vancouver, Canada. Drill core sample preparation includes fine crushing of the sample to at least 70%
passing less than 2 mm, sample splitting using a riffle splitter, and pulverizing a 250-gram split to at least
85% passing 75 microns. Gold in diamond drill core is analyzed by fire assay and atomic absorption
spectroscopy of a 30 g sample (Au-AA25). Multi-element chemistry is analyzed by 4-Acid digestion of a
0.25-gram sample split (ME-ICP61) with detection by inductively coupled plasma emission spectrometer
for a full suite of elements. Gold assay technique Au-AA25 has an upper detection limit of 100 ppm. Any
sample that produces an over-limit gold value via the initial assay technique is sent for gravimetric finish
via method Au-GRA21. Silver analyses by ME-ICP61 have an upper limit of 100 ppm. Samples with
over-limit silver values are first re-analyzed by ICP with a larger 0.4 g sample split, which has an upper
limit of 1,500 ppm. Silver assays above 1,500 ppm are re-analyzed by fire assay with gravimetric finish
Ag-GRA21. ALS Labs is an ISO/IEC accredited assay laboratory.
