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 two 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 RIRG 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.

TORONTO, March 13, 2025 (GLOBE NEWSWIRE) -- Goliath Resources Limited (TSX-V: GOT) (OTCQB: GOTRF) (FSE: B4IF) (the "Company” or "Goliath”) is pleased to report updated modelling confirms the large gold rich stacked layered system of 1.2 kilometres over an area of 1.8 square kilometres is directly associated to a Motherlode Reduced Intrusive Gold System (RIRG) source with multiple gold rich feeder dykes at Surebet on its 100% controlled Golddigger Property (the "Property”), Golden Triangle, B.C. Previously reported feeder dyke holes assayed up to 12 g/t AuEq (11.84 g/t Au and 15.61 g/t Ag) over 10 meters and remains open for expansion. These RIRG feeder dykes are up to 25 meters wide and exposed at surface along strike for up to 1,500 meters and remain open. 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 stack veins, suggesting a syngenetic relationship between these two mineralization stages.

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 quick start 2025 program based on strong assays results from the first 4 feeder dykes tested in 2024. These provide for excellent potential to vector in and target the gold mineralizing system. 4 of the feeder dykes 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 drill holes from 2021 - 2024 with highly prospective intervals of mineralized porphyritic dykes will relogged and assayed as part of the 2025 program that suggest possibly >900 meters of new samples for assaying early on in the season; mobilization is scheduled for May this year.

Dr. Quinton Hennigh, Geologic/Technical Director of Crescat Capital, a strategic investor in Goliath, states: "At the Surebet Discovery, we now see compelling evidence of the causative intrusion that generated this remarkable high-grade gold system. A series of steeply dipping dykes encountered in some recent diamond drill holes bear quartz-sulfide veins and veinlets with compositions strongly similar to those of the numerous shallow dipping and flat lodes that have been the main focus of exploration to date. Age dating shows that the emplacement of these dykes is very close to the age of mineralization. This is intriguing for three reasons. Firstly, it indicates that the dykes themselves are a very prospective, potentially extensive exploration target. Secondly, the dykes and mineralisation forming fluids are clearly tapping the same structures, ones that are presumably deeply rooted and coming from a parent magma source at depth. This could mean there is a lot more gold in the system to explore under and laterally at the Surebet Discovery. Lastly, it is also immediately evident that there is a spatial relation between these dykes and the location of most of the highest grade intercepts encountered to date. In short, we now have a clear vector to guide future drilling at high-grade areas. The 2025 drill season cannot start soon enough.”

Randall Karcher, CASERM researcher and PhD student at the Colorado School of Mines, states: "The granitoid dykes at Surebet have several characteristics which indicate they are part of the system responsible for gold mineralization on the property. Gold in the mineralized dykes occurs within composite grains alongside native bismuth and bismuth tellurides. This style of gold mineralization is also found in the gold rich quartz vein elsewhere at Surebet. Furthermore, the dykes are felsic-intermediate ilmenite series granitoids, which is the expected composition of a causative intrusion in the setting where Surebet was formed. Finally, coincident geochronology between the dykes and the sedimentary/volcanic rock hosted stacked veins indicates that the dykes were emplaced at a time indistinguishable from the veins, suggesting a syngenetic relationship between the two. The discovery of gold bearing intrusive rocks of this character provide strong exploration implications for the intrusive "feeder system”. Additionally, the abundance of local intrusive rocks at Golddigger of similar ages to mineralization show strong exploitation potential moving forward.”

Roger Rosmus, Founder and CEO of Goliath, states: "Recently completed detailed modelling of our drilling to date has shown that in addition to a series of gently dipping vertically stacked veins over 1.2km at the Surebet high-grade gold discovery, there are also a series of near vertical RIRG gold mineralization within the dykes. Our geological team is excited about these dykes and stacked veins being roughly the same age in geological terms that point to a Motherlode RIRG source. If one considers that there are stacked veins dipping toward the southeast and others to the southwest, plus the network of vertical dykes with the higher-temperature gold and occurs with a strong bismuth-gold suggests they are connected and proximal to the source. Things are shaping up to look like we have the potential for a combination of stacked veins similar to the Pogo Mine in combination with a RIRG system like Snowline's discovery in the Yukon. Both the Pogo Mine and Snowline's discovery are part of the Tintina Gold Province, and it is remarkable that we could see something similar as part of the same system in the prolific Golden Triangle to the south of the Tintina Gold Province. We look forward to a quick start to our exploration season in May 2025 this year, we will be relogging and assaying the 19 holes of feeder dyke core drilled between 2021 - 2024 that could possibly end up being >900 meters being sent to the lab. Drilling this exploration season will look to further expanding the stacked veins and dykes for vectoring into the source of the gold system at the Surebet Discovery.”

Dykes - drilling results previously reported:

The dyke is up to 25 meters wide and strikes north-south for 1,500 meters on surface with 900 meters of vertical relief and remains open.

The granitoid dykes at Surebet have several characteristics which indicate they are part of the system responsible for gold mineralization on Surebet. 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 stack veins, suggesting a syngenetic relationship between these two mineralization stages.

Table 1: Highlighted drill holes that intercepted RIRG in dykes - previously reported.

All 4 dykes logged and assayed contained high-grade gold intervals that displayed visible gold, as well as molybdenite, bismuth and tellurium mineralization. An additional 13 dykes have been intersected in drill holes and/or mapped on the surface and 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 additional resource potential.
