Goliath Resources Updated Modelling Confirms Its Large Gold Rich Layered System Is
Directly Associated To Motherlode Intrusive Source (RIRG) And Multiple Gold Rich
Feeder Dykes That Assayed Up To 12 g/t AuEq Over 10 Meters That Remain
Open For Expansion, Surebet Discovery, Golden Triangle, B.C.
Dyke Highlights:
17 feeder dykes have been intersected in drill holes and/or mapped on surface, of which 13
remain to be tested. These will be logged, sampled and assayed in the upcoming 2025
program based on strong assays results from the first 4 dykes tested in 2024 providing for
excellent potential to vector in and target the gold mineralizing system.
4 feeder dykes drilled, logged and assayed contained high-grade gold intervals that displayed
visible gold, as well as molybdenite, bismuth and tellurium mineralization related to a
Reduced Intrusion Related Gold System (RIRG).
19 holes drilled in 2021 - 2024 with highly prospective intervals of mineralized porphyritic RIRG
dykes will be relogged as part of the 2025 program that suggest possibly >900 meters of new
samples for a quick start of early assaying this season; mobilization planned for May 2025.
High-grade gold mineralization was reported earlier this year from a relogged drill hole from
2022 that assayed 12.03 g/t AuEq (11.84 g/t Au and 15.61 g/t Ag) over 10.00 meters , plus a
second separate interval of 8.59 g/t AuEq (8.35 g/t Au and 20.74 g/t Ag) over 5.00 meters that
intersected a feeder dyke derived from the Motherlode gold -rich Reduced Intrusion Related
Gold System (RIRG) source. Additional feeder dykes have also confirmed gold mineralized
intrusion related in drill holes to a down-hole depth of 500 meters with grades ranging from
1.08 g/t AuEq over 1.10 meters to 10.50 g/t AuEq over 7.00 meters. The gold mineralized feeder
dykes are up to 25 meters wide and exposed along strike at surface for up to 1,500 meters and
remain open, strongly indicating close proximity to a gold-rich Motherlode RIRG source.
Mineralization in the dykes occurs as quartz veins and veinlets up to a few centimeters wide
containing visible gold, bismuth, bismuth-tellurides and molybdenite, hosted in porphyritic
felsic-intermediate ilmenite series granitoids, which is the expected composition of a causative
intrusion in the geologic setting where Surebet was formed . Gold in the mineralized dykes
occurs included in composite grains with native bismuth and bismuth tellurides . This style of
gold mineralization is also found in the gold-rich staked shear hosted quartz veins at Surebet.
The geochronology (age) between the dykes (52.0 ± 1.5 Ma) and sedimentary/volcanic rock
hosted stacked veins (50.7 ± 1.0 Ma) indicates the dykes were emplaced at a time
indistinguishable from the stacked veins, suggesting a syngenetic relationship between these
two mineralization stages. Also, there are t wo stages of gold mineralization observed
petrographically in all gold bearing veins at the Surebet Discovery (see more information
below).
Two stages of gold mineralization are observed petrographically in all gold bearing veins at the
Surebet Discovery. The first stage is higher-temperature and occurs with a strong bismuth-gold
association, which is most commonly observed in the RIRG dykes. This is further evidence these
are the feeder pathway structures that provided mineralization for the high-grade gold stacked
veins. The second is a lower temperature stage most commonly found in the sedimentary rocks
and volcanic rocks. Certain intervals are observed containing both high temperature and low
temperature stages of gold i.e. previously announced drill hole GD-24-260 that ran 34.52 g/t
AuEq (34.47 Au and 3.96 Ag) over 39 meters, including 132.93 g/t AuEq (132.78 Au and 12.98
Ag) over 10.00 meters.
During only 15 months of boots on the ground, strong gold mineralization has been confirmed
with assays in 100% of 243 widespread drill holes containing >300 intercepts to date within a
1.8 km2 area. Confirmation of multiple stacked gold veins and widespread gold -rich reduced
intrusion (RIRG) feeder dykes, confirms the continuity of the widths and grades at Surebet
demonstrating this world -class gold system has tremendous untapped expansion potential
remaining.
Confirmation of high gold grades over broad intervals in the recently discovered RIR G system
characterized by considerable amounts of visible gold, bismuth, bismuth tellurides and
molybdenum mineralization in the felsic to intermediate porphyritic dykes on Surebet
materially increases the resource potential of the Surebet discovery. Targeting the feeder
dykes and Motherlode gold -rich source will form part of the drill program in 2025 as well
expanding the stacked layers of high-grade gold mineralization currently covering at least 1.8
km2 that remains open in all directions on the Surebet discovery.
