Outer Rim Exploration Detects Copper Mineralization Using OreScope Muon Imaging at Transatlantic Monitor ProjectMay 11, 2026 7:30 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - May 11, 2026) - Transatlantic Mining Corp. (TSXV: TCO) (the "Company") and Outer Rim Exploration (ORE) announce the successful completion of a muon imaging survey at the Monitor Copper-Gold Project in Idaho, marking the first North American deployment of ORE's portable muon hodoscope for mineral exploration.The underground campaign successfully detected a density anomaly aligned with the known steeply dipping chalcopyrite-bearing structure and identified additional high-density targets that may represent extensions of the copper mineralized system using the "OreScope" TM Imaging technique.The survey was designed to evaluate the continuity and potential extensions of the copper mineralization and to improve understanding of the subsurface structure. The modelling and imaging provide higher confidence on highly localized information to better optimise the drill targeting. ORE's muon imaging helps characterize the density structure and, in the future, could define new drill targets and then from the drilling itself. The results demonstrate that muon-derived density imaging can detect narrow mineralized structures and generate exploration targets from an underground deployment position.Successful Detection of Known Copper MineralizationThe underground deployment produced density contrast maps revealing a coherent high-density feature aligned with the known chalcopyrite vein. The anomaly's location, orientation, and inferred dip are consistent with the geological ground-truth model.Quantitative comparison between measured and hypothesized densities yields a correlation coefficient of r = 0.46 (p < 0.001), indicating a statistically significant agreement.The inferred dip of the anomaly is consistent with the approximate 80° dip indicated by geological mapping in the adit, supporting the interpretation that the detected feature corresponds to the known copper-bearing structure."These maiden muon trial results are highly encouraging," said Bernie Sostak, CEO of Transatlantic Mining. "The imaging survey identified a density anomaly consistent with our known chalcopyrite mineralization and highlighted additional areas that may represent extensions of the known system. This provides valuable information to guide and target follow-up exploration and drilling." New Exploration Targets IdentifiedIn addition to confirming the known vein, the survey identified multiple high-density anomalies outside the modeled extent of the mineralization.These include:A prominent ~3-sigma density anomaly (~2.95 g/cm³) adjacent to the known veinAdditional ~2-sigma anomalies (~2.7 g/cm³) spatially clustered near the target zoneIndependent high-density features observed across multiple viewing anglesThese anomalies may represent extensions of the mineralized system given that there are no drillholes in the vicinity of the Adit, again to provide targets for future drilling campaigns.3D Density Model GeneratedData from multiple detector placements were combined to generate a 3D density reconstruction of the surveyed volume. The model highlights zones of elevated density consistent with both the known mineralization and newly identified anomalies.Maiden North American DeploymentThe campaign represents the first North American deployment of ORE's portable muon hodoscope for mining applications. The detector was deployed underground in a battery-powered, passive configuration, operating continuously over multiple weeks.The system was used to evaluate mineralization continuity and characterize subsurface density variations without drilling or active radiation sources.Exploration and Mine Planning ImpactBy imaging both mineralized zones and surrounding density variations, the survey provides insights into orebody geometry and potential extensions of copper mineralization. These results may support future drill targeting, mine planning, and reduction of exploration uncertainty."The value of this technology is that it helps us see beyond isolated drill-hole data," said Sostak. "At Monitor, ORE's muon imaging provided a new view of the density structure between known points, highlighted potential extensions of the mineralized system, and gave us actionable targets for follow-up drilling. This can translate directly into optimised targeting, fewer wasted meters, and additional exploration decisions." Exploration ImplicationsThe successful detection of the known chalcopyrite vein, together with identification of additional density anomalies, supports the use of muon imaging as a complementary exploration method for targeting dense sulfide mineralization.Further deployments may refine the geometry and continuity of the identified targets and expand coverage beyond the initial survey area.ORE Modelled 3d density prediction (left) and Anvil Adit (right) in IdahoTo view an enhanced version of this graphic, please visit:

Transatlantic Provides Exploration Update for its Copper and Gold Projects in Montana, IdahoMay 5, 2026 7:30 AM
NewsfileVancouver, British Columbia--(Newsfile Corp. - May 5, 2026) - Transatlantic Mining Corp. (TSXV: TCO) (the "Company") is pleased to provide an exploration update on its three key projects in Montana and Idaho: The Miller Mine and Golden Jubilee gold projects in Montana, and the Monitor copper-gold project in Montana-Idaho.The Miller Mine drill permits have been submitted for approval and are in process for the surface drilling. The company has now received an extended permit for underground drilling at the Jonnie Gulch Adit, which has focus on the lower Miller Mine target. This permit allows for up to 12 holes underground at approximately 250 metres (800 feet) each. Transatlantic is currently pursuing quotes for drilling. Trucking permits are also in progress, being applied for roads over US Forest Service lands to access the historic stockpiles. The company is pursuing metallurgy and recovery tests for the Miller Mine stockpiles in 2026. Transatlantic anticipates releasing an NI-43-101 technical report for the Miller Mine by Q4, 2026. The scope of work and cost estimates for the Golden Jubilee NI 43-101 maiden resource estimate and technical report are now being sourced to be determined. The 2026 follow-up drill program, now approved and permitted to December 31, 2026 will further test the down dip extension and plunge of the main zone of mineralization. Transatlantic will also test a geophysical offset target that has not previously been drilled. Additionally , the current permit allows for Transatlantic to dewater the mine and survey and map it for further exploration potential. At Golden Jubilee, the current plan envisages for Transatlantic to drill up to 2,000 metres in 2 to 4 holes to moderately shallow depths of 300 to 400 metres.At the Monitor copper-gold project a geophysical survey and associated workplan will be undertaken after and as a follow up to the Trial Muon Study recently completedIn December the company engaged a technical trial with Outer Rim Exploration utilising a new Muon enhanced technique to identify voids and new mineralisation association at Monitor. The Muon imaging was used to target new high density copper zones around the Anvil Adit Prospect. A full report is expected shortly in the coming weeks. On Dec 1, 2025, Transatlantic released an NI-43-101 Maiden Technical Report and Exploration Target on the Monitor Project as follows:To view an enhanced version of this graphic, please visit:

There has been insufficient exploration to estimate a Mineral Resource and it is uncertain if further exploration will result in the estimation of a Mineral Resource. (See news release and Technical Report filed December 1, 2025)The Report called for a Three-Phase Exploration Program: Phase 1 - Underground Exploration: Rehabilitation of existing underground workings, systematic channel sampling and mapping, underground drilling, and an option for the collection of a 10,000-tonne bulk metallurgical sample. This phase will provide high-quality geological data while generating material for comprehensive metallurgical testing. Phase 2 - Property-Scale Surveys: Detailed geological mapping, geophysical surveys (magnetic and IP/resistivity), and petrophysical analysis to identify additional targets and refine the geological model. Phase 3 - Targeted Surface Drilling: Surface drill programs will be designed based on underground results, focusing on down-plunge extensions and potential stratiform mineralization in the underlying Revett Formation."The Company is looking forward to progressing the 3 projects in 2026 with additional mapping , permits, drilling and technical reports, " said Bernie Sostak.

Transatlantic grab samples up to 27.59 g/t Au at Miller

2023-06-14 14:46 ET - News Release

Mr. Bernie Sostak reports

TRANSATLANTIC MINING: EXTENSION AND EXECUTION OF FIRST RENEWAL TERM, NEW ASSAYS RECEIVED OF 27.6 G/T AU AT THE MILLER GOLD MINE

Following meeting the conditions of the initial term, Transatlantic Mining Corp. has now executed the first renewal term with an option to purchase by a mining royalty. The company has also opened a new winze drive, with the first grab samples taken from the lowest level uncovered in the mine. Pumping continues in this lower-level winze drive to determine the full length extent of the winze.

The Miller gold mine is located in the Broadwater county in Montana, United States. The mine is approximately 29 miles to the northeast of Townsend in Montana. The presence of gold mineralization has been confirmed by recent sampling in areas of the mine where access is possible.

Highlights

Miller mine -- lower level:

Opened up lower winze level immediately below the lower level.
First grab samples from lower-level winze -- 27.6 grams per tonne (g/t) gold (Au), visual gold has also been observed.
Extended lease agreement to first renewal term with option to purchase by production royalty.
Key components of the activity

Transatlantic has nearly completed recovering a majority of the mud on the Miller mine lower portal over the gravity table. With continued pumping, the mine has further uncovered a new lower winze drive, previously under water. This development continues to be pumped to determine the full extent of this newly opened old development.

An initial set of two samples were taken on the initial accessible floor of this lower winze development, with the assay results received as shown in the table entitled "Lower-level winze drive initial grab sample assays."


Upon access to the dewatered lower-level winze drive, 30 metres of strike is now visual on a minus-20 degree gradient with water still at the drive face. In the exposed mine development, visual gold has been observed in the wall, roof and floor.

Given the initial grab samples are encouraging with gold and the visual aspect, further in situ samples will be taken for assay once the water has been cleared to the end of the drive.

Mud over the gravity table was suspended during the poorer weather conditions until warmer weather conditions prevail. Weather has now improved and the trial processing activities will recommence once assays are received from the laboratory on the muds. Trial processing of some hard rock samples will be undertaken in the near future for gravity extraction analysis as the company sources suitable pulverizing equipment.

About the Miller mine and claim group

Transatlantic has access to the upper and lower level of the mine. The Miller mine is situated amongst patented and unpatented claims at an elevation of 1,920 m (6,400 feet) and accessible by roads 50 miles from Helena, Mont.,U.S. Should mining occur at any time, an 8.5-per-cent royalty on ounces is to be paid. During the term of the agreement, the company may purchase the property for $4.5-million (U.S.), less the royalty payments made above, with a perpetual 1-per-cent NSR (net smelter return) to the vendor thereafter.

The gold and silver mineralization generally occurs on the contacts of sediments and igneous intrusive with native gold and sulphides, including pyrite, often observed amongst the four known adits located on the property.

"The extraordinary efforts of the historical miners in developing a declined winze at steep angles is testament to the belief that gold is still there. The first samples from this lower winze drive indicate good gold grades that will be followed up further. To see gold in the first instance is a good indicator for more gold," commented Bernie Sostak, chief executive officer of Transatlantic Mining.

The new rock chip samples are grabs from the winze level drive were of five kilograms in weight. The samples were crushed in whole to plus 70 per cent passing two millimetres, and then split and pulverized with analysis for gold and silver at the Christofferson Laboratory, Smelterville, Ida., U.S. The laboratory is an independent assay and umpire laboratory that follows industry techniques. The samples, after being pulverized are analyzed with a 15-gram to 30 g fire assay charge were gravimetrically finished.

OVERALL PERFORMANCE / DISCUSSION OF OPERATIONS

Monitor Property

The Company has focused and now received the 12-month drill permits for drill programs and metallurgical testing of mineralized rock at the Big Elk Copper Prospect. At December 31, 2022, the Company has refundable performance bonds of $54,065. Drilling Contractors are being sourced for the Summer of 2023.

Miller Mine Gold Project

A new Winze has been identified on pumping down the Lower Level which will be part of a future sampling campaign once dry. The Winter has been set up with transporting the gravity table into the Lower Level of the mine to run the muds over it.

New drilling and sampling is planned on the Lower Level development once the Lower Level and Winze drive are pumped out and cleared.

Golden Jubilee Property

The Golden Jubilee Gold Project, had a 50 line and 50 metre spaced Geophysical Land Survey partially completed. This ground survey was undertaking IP (Induced Polarisation) and resistivity data collection of 5,000 line metres in total. To date, the initial data survey has identified new targets and extensions outside the current mine footprint to 1 kilometre in strike.

A follow up to the next stage of work will be completed once new assays are received and water permit received. Dewatering Discharge permits have been drafted for submission to the receiving government bodies.

Business Development

The Company continues its activities with focus on the Miller Mine, Monitor Mine and Golden Jubilee Property. In addition, reviewing technical considerations to evaluating other projects and to maximize the technical value of these high grade Gold and Copper Projects. The Company is reviewing surface diamond drill machines for future owner deep drilling and will utilize its own fleet and contractors as best resource which becomes available.

Transatlantic drills 6 m of 13 g/t Au at Golden Jubilee

2023-04-13 15:59 ET - News Release

Mr. Bernie Sostak reports

TRANSATLANTIC MINING: DRILLING RESULTS AT THE GOLDEN JUBILEE MINE INCLUDE AN INTERSECTION OF 6.1 M AT 13.1 G/T AU

Transatlantic Mining Corp. has released assay results from the most recent drilling program. The drilling at the Golden Jubilee mine consisted of 10 reverse circulation holes for a total of 2,000 metres. This mine is located in Granite county, Montana, United States. The results from this drilling program confirm that the mineralized structure continues downdip and along strike from mineralization, which has been either mined previously or delineated by earlier drilling.

Highlights

New drill results:

Drill hole No. 2201:
9.1 metres at 7.8 grams per tonne gold from 64-metre depth (8.0-metre true width) (including 1.5 metres at 16.11 g/t Au);
6.1 metres at 5.5 g/t Au from 86.9-metre depth (5.5-metre true width);
Drill hole No. 2203:
6.1 metres at 13.1 g/t Au from 111.3-metre depth (6.0-metre true width) (including 3.0 metres at 17.3 g/t Au).
Drilling

The company has completed its inaugural drilling campaign into the Golden Jubilee deposit and is reporting the available assay results from the 10 holes drilled. These are shown in an attached table. The company was fully financed to complete this program and has funds available to undertake follow-up additional work. The mineralization has been intersected downdip and along strike of existing drill holes and underground workings. There is also further evidence that there are an additional two mineralized zones in the footwall and hangingwall of the targeted Golden Jubilee mineralized structure. These outcomes provide encouragement to undertake more drilling to follow up on several geophysical targets which indicate that the mineralized structure extends for up to an additional one kilometre of strike. New exploration drill permits will be sought to facilitate this drilling. The company is also evaluating the current water and operating permits with the relevant government departments. The gold mineralization intersected by the reverse circulation drilling is associated with a shear-hosted iron quartz, sulphide-rich replacement zone.

Some characteristics of the mineralization and drill program include:

Drilling indicates that it is shallow, between 30 and 240 metres from surface.
The contacts to the mineralization are in competent marblized limestones.
The mineralized zones are visibly distinct.
It occurs in multiple parallel mineralized structures.
"The first phase of drilling and results continue to support the presence of mineralization below the lowest mine level. There is rising confidence in parallel mineralized zones that will require additional drilling. Not only does the main zone at the Golden Jubilee continue, but recent geophysics has highlighted targets and offsets one kilometre along strike. This information with existing high-grade production and processing information will support and develop our model of the high-grade and exploration structures further," commented Bernie Sostak, chief executive officer of Transatlantic.

Recent reverse circulation drill assay results for gold at greater than 3.0 g/t Au

About Golden Jubilee

The 22 Golden Jubilee claims are situated in Granite county, Montana, United States, and have had a number of previous owners. There have been only limited exploration and mining on the regional Red Lion (vein) line trend, which is known to continue over a regional strike of seven kilometres in length. The Golden Jubilee mine is located in mountainous country at an elevation of approximately 2,350 m.

Historical production

Although some mining occurred prior to the year 2000, there are limited production records in existence. An attached table contains the results from a bulk sample taken in 2000 and the more recent 10,000-tonne parcel mined over a five-month period in 2014.

Historical drilling

Previous exploration drilling has included 37 holes drilled prior to 2013, where the gold mineralization and vein had been observed to be approximately 2.5 m wide with an 80-degree dip. Enrichments and wider mineralization widths have been observed on geological cross-structures striking at an obtuse angle to the Red Lion vein trend.

* The new reverse circulation drill samples were crushed in whole to plus 70 per cent passing two millimetres and then split and pulverized with analysis for gold and silver at the Christofferson laboratory, Smelterville, Idaho, United States. The laboratory is an independent assay and umpire laboratory that follows industry techniques with blanks and standards inserted on batches of 25. The samples are pulverized and analyzed with a 15- to 30-gram fire assay charge and a gravimetric finish. True widths were estimated based on the dip cross-section width of the mineralization at a 1.0 g/t Au cut-off. An attached table sets out historical holes drilled and assayed. The company also adds a standard to determine any assay bias.

Further announcements will be made in regard to the activities as they transpire.

2.Transatlantic Mining (TSXV:TCO) Company Profile

Weekly gain: 89.47 percent; current share price: C$0.18; market cap: C$15.6 million Transatlantic Mining is a gold and copper exploration company with three projects, all of which are in the US. Its two gold projects, Golden Jubilee and the Miller mine, are in Montana, while its copper-gold project Monitor is in Idaho. Much of last year's exploration focused on Golden Jubilee, but the company has begun this year with work at the small-scale, past-producing Miller mine. Transatlantic is earning into Miller with a gold royalty and is reviewing its condition and infrastructure. On January 30, the company announced that it is currently clearing mud and dewatering the existing mine. The mud it has removed was passed over a gravity table, revealing visible gold. The company shared that these results have encouraged it to continue processing the mud it removes from Miller for gold.

Transatlantic passes Miller mud over gravity table

2023-01-30 16:52 ET - News Release

Mr. Bernie Sostak reports

TRANSATLANTIC MINING COMMENCED RUNNING GRAVITY GOLD TABLE TRIAL AT THE MILLER GOLD MINE

Following completion of the Miller mine portal, Transatlantic Mining Corp.'s mine has been re-entered to clean up accumulated mud and dewater areas where the existing mine development is under water.

A large sample of mud was passed over a gravity table to ascertain if it contained any gold. Visible gold was observed on the gravity table in sufficient quantity to encourage the further processing of this mud.

Dewatering of the mine is being undertaken concurrently with the removal of the mud. This will give access to parts of the old mine last worked in the 1960s.

The Miller gold mine is located in the Broadwater county in the state of Montana, United States. The mine is approximately 29 miles to the northeast of Townsend in Montana, United States. The presence of mineralization has been confirmed by recent sampling in areas of the mine where access is possible.

At the company's Golden Jubilee property, final assay results from the recent 10-hole reverse circulation drill program are pending.

Highlights

Miller mine:

Lower level completed securing portal entrance for winter access;
Dewater older and deeper parts of the mine where visual gold has now been observed in situ;
Commissioned and installed a gravity table into the lower level of the mine.
Key components of the activity

Transatlantic has entered into the Miller mine lower portal and secured the entrance for winter. Work has taken place to remove mud from the lowest level in the mine which was waist (approx 1.5 metre) deep over 200 metres in part.

The company decided to extract the muds out of the mine and run them over a gravity table to ascertain if they contained gold. Gold has been clearly identified, and further work is being undertaken to determine the quantum of the gold content. This was in concert with dewatering an older area in the mine that has not been reached previously. This dewatering also aided in providing further access for additional geological reconnaissance, sampling and additional drill planning activities.

Upon access to the dewatered mine drive, 30 metres of strike is visual on a minus-10-degree gradient with water still at the drive face. In the exposed mine development, visual gold was observed in the wall, roof and floor.

The first rocks out of the old level contain visual gold and sulphide within this newly opened deepest level. It is unknown what the final depth of this drive is. Dewatering will continue until completely dewatered. Once this has occurred, a campaign of geological sampling of the mine wall, roof and floor will be undertaken to assay for gold. The deepest level is now exposed for about 30 metres in length and is approximately two metres wide.

A gravity table has been set up in the mine to trial process the muds that have been extracted out of the mine. The concentrate has been sent to the assay laboratories for analysis, but with panning, it is apparent that large particles of gold are apparent in the concentrate.

About the Miller mine and claim group

Transatlantic has access to the upper and lower level of the mine, where it is currently safe to do so. The Miller mine is situated amongst patented and unpatented claims at an elevation of 1,920 metres (6,400 feet) and accessible by roads 50 miles from Helena, Mont., United States.

The gold and silver mineralization generally occurs on the contacts of sediments and igneous intrusives with native gold and sulphides including pyrite often observed amongst the four known adits located on the property.

"The current team efforts at the Miller mine support that there is still gold mineralization remaining from the historical mine efforts. We look forward to sampling and dewatering the deepest part of the mine further, where visual gold is often observed. Additional diamond drilling will be planned following the geological and technical investigation and assessment of this opening. To see gold in the first instance is a good indicator for more gold in the future," commented Bernie Sostak, chief executive officer of Transatlantic.

I usually would post a more thorough due diligence report, but the new company presentation lays everything out clearly. Extremely high-grade gold and copper projects that are all located in the United States. Lots of cash to work with, heavy ownership by only a handful of investors, great projects.

Please do your own due diligence before investing.
