LAVRAS GOLD DISCOVERS NEW GOLD DEPOSIT AT
LDS PROJECT IN BRAZIL
Matilde features continuity along strike and at depth, pockets of high grade
associated with visible gold
TORONTO, ONTARIO – November 3, 2022 – Drilling and assay results from Lavras Gold Corp.’s
(TSXV: LGC) LDS Project in southern Brazil confirm that a significant new gold deposit has been
found at its Matilde target. These results come just two months after Lavras Gold announced
bonanza gold grades at Zeca Souza and three months after a NI 43-101 compliant resource for
the Cerrito Deposit increased the Company’s consolidated gold resources to 1 million ounces.
“We are very gratified with these results from Matilde,” said Michael Durose, Lavras Gold’s
President and Chief Executive Officer. “We are seeing long broad zones of continuous
intercepts of important gold mineralization accentuated with multiple narrower higher-grade
intervals and in certain instances, bonanza gold grades associated with visible gold.
“Long continuous zones of gold mineralization both laterally and to a vertical depth of more
than 480 metres where it is still open, indicate a very strong and large gold system at Matilde.
“Our next steps will be to follow up on these results to test for extensions to gold mineralization
along strike to the west and to the northeast where we are drilling at Matilde Extension. Work
will also focus on better defining the nature of the structures that host the gold, alteration styles
associated with mineralization, and their relationship to the large 3-kilometre-long gold in soil
anomaly that is centered on the Matilde target.”
Matilde highlights: continuity, open, moderate gold mineralization
accentuated by narrower higher-grade intervals, and bonanza grades
Located approximately 4.5 kilometres south of the town of Lavras do Sul (Figure 1), Matilde is
one of six priority drilling targets. There are 23 known gold occurrences at LDS. Other drilling
targets include Matilde Extension, Caneleira, Vila Marieta, Mato Feio, and Zeca Souza.
Important gold mineralization occurs in 91% or 30 out of 33 holes totalling 10,583 metres drilled
at Matilde to date. This news release discloses new assay results from 26 drillholes totalling
8,367 metres. The results from the other seven historical drillholes are also discussed here for
completeness. Highlights are as follows:
• Strike-length continuity – Drilling has confirmed gold mineralization extends over an east-
west strike length of at least 250 metres.
The structure “bends” to the northwest along the western part of the magnetic anomaly
before trending west again. The structure turns to the northeast at the eastern side where it
strikes towards the Matilde Extension target about 750 metres away.
Drilling is currently testing for extensions of gold in both directions at Matilde where
mineralized zones remain open.
• Depth and continuity open – Long continuous intervals of gold mineralization occur in holes
20MT-001, 20MT-002, 20MT-008, and 22MT-034.
As highlighted in Figure 3, hole 22MT-034 is particularly noteworthy as the hole was drilled
557 metres (approximately 483 metres vertical distance) and bottomed in gold
mineralization. This suggests that Matilde has deep roots, typical of porphyry style mineral
systems.

NEWS RELEASE: Lavras Gold discovers new gold deposit at LDS Project in Brazil (November 3, 2022) 2
Zones of gold mineralization are usually associated with green to musky green coloured
hydrothermally altered granodiorites consisting of sericite (phengite), quartz and 2-3%
disseminated pyrite. These mineral associations are typical of a phyllic style of alteration in
porphyry systems.
However, evidence of potassic alteration is beginning to develop at a depth of approximately
419 metres (drill core interval) in the form of potassium feldspar (see Figure 7). This is
important, as it is common for the potassic zones of porphyry systems to host higher gold
and copper grades.
• Broad continuous zones of moderate gold mineralization accentuated by narrower higher-
grade intervals – As Figure 4 demonstrates, long-intervals of gold characterized by zones of
moderate grades in the 0.4-0.7 g/t gold range are accentuated by narrower higher-grade
intervals typically in the 1-1.5 g/t gold range, but sometimes as high as 2-4 g/t gold. Examples
include:
o 20MT-001 – 62.53 metres grading 0.62 g/t gold from 189.70 metres including 12.77 metres
grading 0.89 g/t gold from 191.48 metres and 14.00 metres grading 1.13 g/t gold from 228.40
metres
o 20MT-002 – 144.60 metres grading 0.69 g/t gold from 117.00 metres including 27.00 metres
grading 1.04 g/t gold from 184.0 metres
o 21MT-008 – 10.00 metres grading 0.88 g/t gold from 83.00 metres including 3.00 metres
grading 1.33 g/t gold from 83.00 metres
o 21MT-026 – 28.00 metres grading 1.05 g/t gold from 174 metres including 8.00 metres
grading 2.59 g/t gold from 189.00 metres
o 22MT-034 – 19 metres grading 0.67 g/t gold from 56.00 metres including 3.00 metres
grading 1.04 g/t gold from 64.00 metres; 29.00 metres grading 0.82 g/t gold from 198.00
metres including 4.00 metres grading 2.57 g/t gold from 203.00 metres; and 2.00 metres
grading 4.13 g/t gold from 205.00 metres.
• Bonanza gold grades (more than 10.00 g/t) usually associated with visible gold – At least
two different relationships have been observed:
o Cross-cutting (interpreted) lamprophyre dykes suggesting a possible gold precipitation
mechanism in at least two areas:
▪ 20MT-002 yielded 0.60 metres grading 30.90 g/t gold from 261.00 metres. Visible gold
specs are observed within an aphanitic glassy matrix of quartz adjacent to a quartz-
carbonate veinlet and an interpreted lamprophyre dyke. The lamprophyre dyke appears
to have assimilated quartz fragments (see Figure 5).
▪ 22MT-034 returned a zone of 1.00 metres grading 2.84 g/t gold from 407.00 metres. The
gold grade seems unusually low given the presence of visible gold and the sample is
being re-assayed. Nevertheless, visible gold is observed within an aphanitic matrix of silica
(glassy quartz) adjacent to an interpreted lamprophyre dyke that appears to have been
silicified (see Figure 6). It is possible this interpreted silicified “lamprophyre dyke” is a felsic
dyke.
o Visible gold associated with a late-stage centimetre-scale cross-cutting milky quartz veinlet
within hydrothermally altered granodiorite (see Figure 7).
▪ 22MT-034 returned 0.66 metres grading 13.10 g/t gold from 419.34 metres. The
hydrothermal alteration includes sericite (phengite), chlorite, potassium feldspar, silica,
and hematite. Further work focusing on better understanding the nature of these
relationships is on-going.

• A northeast-southwest structural trend is emerging – This trend leads directly to the
Matilde Extension target about 675 metres to the northeast where drilling is underway. This
structure is interpreted to have been intersected in drillholes 21MT-007 and 21MT-009A.
The geological field team are selecting drill targets to test along this trend. Seven holes have
tested the Matilde Extension target, and results will be released once all assay results are
received.
• Gold targets associated with structures immediately south of Matilde east-west structural
corridor have been identified and require follow-up – These targets are characterized by
coincident magnetic low signatures overlying gold in soil anomalies.
Petrographic work confirms gold from Matilde has a magmatic
hydrothermal origin
In addition to the drilling program, Renaud Geological Consulting of London, Ontario,
completed petrographic studies on samples from the Matilde target (sample 20MT-002)
(Figures 8 and 9).
The study concludes that “Matilde is a highly altered intrusive rock with primary textures
dominantly replaced by hydrothermal alteration. The rock has undergone multiple
hydrothermal events dominated by poikilitic growth of hydrothermal quartz and feldspar.
“The rock is dominated by a distinctive green-yellow colour attributed to a groundmass of
phengitic micas, chlorite, and albite. The rock appears brecciated and sealed by extremely fine-
grained phengitic-paragonitic muscovite, albite, iron-chlorite, and manganese-iron carbonate.
Sulphide minerals include pyrite, arsenian pyrite, arsenopyrite, marcasite, silver-bearing
tetrahedrite, and electrum. The rock is cross-cut by late-stage anastomosing veinlets of quartz-
carbonate.”
These conclusions add to the growing evidence that the gold-bearing fluids that formed
gold at Matilde are of a magmatic hydrothermal origin, and that this is primarily a large
intrusive hosted gold system with epithermal and porphyry characteristics.
Discussion of drilling results
The drill program tested a portion of a coincident 3.0 kilometre long gold in soil anomaly
centered on an east-west trending magnetic-low anomaly (Figure 2) that is interpreted to be a
major gold-hosting structure. Drilling defined a gold system hosted within an east-west
structural corridor in hydrothermally altered granodiorite. Gold mineralization begins at surface
and has been traced over a strike length of at least 250 metres and to a minimum vertical
depth of 483 metres. The deposit is open to expansion along strike and at depth.
In a general sense, the mineralization consists of broad zones of moderate-grade gold
accentuated by narrower intervals of higher-grade. In addition, bonanza gold values are usually
associated with visible gold adjacent to interpreted lamprophyre dykes and late-stage milky
quartz veins.
Typical alteration mineral associations include quartz, sericite and pyrite, and occasionally
visible gold suggesting a phyllic style of alteration associated with porphyry systems.
However, there is evidence that a potassic style of alteration is beginning to develop at depth as
evidenced by pink potassium feldspar at a drill core depth of 418 metres in 22MT-034 (see figure
7). This is important, as higher gold and copper grades typically exist in the potassic zones of
porphyry systems.

EAST-WEST STRUCTURAL CORRIDOR
Thirty-three drillholes totalling 10,583 metres evaluated part of a 3-kilometre-long gold-in-soil
and magnetic low anomaly centered on the Matilde gold target.
The latest drilling program followed up on two major intervals of gold mineralization discovered
in a 2020 drilling program defined by drillholes 20MT-001 and 20MT-002.
These two holes intercepted a major east-west gold-bearing structural corridor over a 50-metre
strike length demonstrating that gold mineralization begins at surface and shows good
continuity over broad intervals and across a wide structural corridor. Highlights from this
previous drilling includes:
• 20MT-002 – drilled from north to south across a gold-bearing structure returned 144.60
metres grading 0.69 g/t gold from 117.00 metres including 92.60 metres grading 0.87 g/t gold
from 170.00 metres, 8.00 metres grading 1.02 g/t gold from 174.00 metres, and 27.00 metres
grading 1.04 g/t gold from 184.00 metres.
The follow-up program focused on extending the strike extension of the east-west mineralized
corridor and the down dip extension. The program has been successful on both fronts.
The strike length was increased five-fold to 250 metres, and known mineralization was nearly
doubled from a vertical distance of 250 metres in drillhole 20MT-002 to 483 metres in drillhole
22MT-034.
Matilde remains open along strike and at depth. Highlights of drilling are as follows:
• 21MT-008 – collared 112 metres west of 20MT-001 and drilled from north to south returned
multiple zones of gold mineralization from surface to the end of the hole at a depth of 415.55
metres. The hole bottomed in gold mineralization and remains open. Highlights include:
o 1.60 g/t gold over 3.02 metres from 48.30 metres
o 2.03 g/t gold over 3.43 metres from 56.23 metres
o 0.88 g/t gold over 10.00 metres from 83.00 metres including

o 0.76 g/t gold over 15.55 metres from 351.0 metres including
▪ 1.34 g/t gold over 4.00 metres from 355.00 metres
• 22MT-027 – collared about 60 metres west of drillhole 21MT-008 and drilled from south to
north. The purpose was to try to understand the dip direction of the east-west structural
corridor. The gold-bearing east-west structure was encountered as follows:
o 0.41 g/t gold over 25.76 metres from 254.24 metres including:
▪ 0.93 g/t gold over 0.88 metres from 255.12 metres
▪ 0.74 g/t gold over 8.00 metres from 272.0 metres
▪ 1.01 g/t gold over 1.00 metres from 279.0 metres

• 22MT-028 – collared 62.00 metres east of hole 22MT-027and drilled from south to north. The
purpose of this hole was to test the dip direction of the east-west structural corridor. Multiple
zones of elevated gold values were encountered throughout the hole beginning from surface
including:

NORTHEAST STRUCTURAL CORRIDOR
In addition to the east-west structural corridor, there may be a northeast trending structure
beginning to develop.
Holes 21MT-007 and 21MT-009A appear to have intersected mineralization striking in a
northeast-southwest direction parallel to a northeast-southwest magnetic low anomaly in the
aeromagnetic data. This structural trend continues 675 metres towards the northeast where
the Matilde Extension target is being drill tested.
The main intercepts near Matilde that tested this northeast trending structure include:
• 21MT-007 – collared south of the major east-west structure and drilled from south to north.
This hole intersected:
o 0.76 g/t gold over 17.68 metres from 68.00 metres including
▪ 1.24 g/t gold over 3.0 metres from 73.00 metres
• 21MT-009A – collared south of the major east-west structure and drilled from south to north.
This hole returned multiple intercepts from the beginning of the hole. Highlights include:
o 1.08 g/t gold over 19.00 metres from 137.00 metres including
▪ 4.74 g/t gold over 1.00 metres from 137.00 metres
▪ 1.32 g/t gold over 6.00 metres starting from 150.00 metres.
Next steps
These drilling results are being incorporated into the geological database for further
interpretation and analysis. The 16,000-metre drilling program is on-going and consists of two
drills. The program will continue to test for extensions of gold mineralization to the
west/northwest and east/northeast at Matilde. The down dip extensions of mineralization will
also be further investigated.
Drill targets will also examine Matilde Extension where another mineralized zone is being
defined. Results from Matilde Extension will be released once all assays have been received.
A drill was also recently mobilized to Zeca Souza to follow up on positive results disclosed earlier
this year.
An on-going regional soil survey is underway, and results will be integrated with the regional
aeromagnetic drone survey that was completed in the summer.

Drill core is logged and sampled in a secure facility located in Lavras do Sul, Rio Grande do Sul
State, Brazil. Drill core samples for gold assay are cut in half using a diamond saw and
submitted to ALS Laboratories Inc. in Goiania, Goiás State, Brazil for preparation by crushing to
70% passing 2.0 mm, riffle splitting to obtain 500 g aliquots, and pulverizing to 85% passing 75
microns.
Pulps are shipped to ALS Laboratories in Lima, Peru and analyzed by a 30 g fire assay and AAS
finish. For assays above 10 ppm gold, a cut of the original pulp was re-assayed with a
gravimetric finish.
Certified standards, non-certified blanks and field duplicates are inserted into the sample
stream at regular intervals, so that QA/QC accounted for about 10% of the total samples. Results
are routinely evaluated for accuracy, precision, and contamination.
