Drilling Results at the Golden Jubilee Mine includes an intersection of 6.1 m at 13.1 g/t Au

TCO NEWS RELEASE-VANCOUVER, B.C April 13 2023 – Transatlantic Mining Corp. (the “Company”) (TCO:TSX.V) is

pleased to announce 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 2000 m. This mine is located in Granite County, Montana, USA. The results from this drilling

program confirm that the mineralized structure continues down dip and along strike from mineralization which has either been

mined previously or delineated by earlier drilling.

Highlights

New Drill Results

• Drillhole # 2201 - 9.1 metres at 7.8 g/t Au from 64 metres depth ( 8.0 m true width)

(Including 1.5 metres at 16.11 g/t Au)

6.1 metres at 5.5 g/t Au from 86.9 metres depth ( 5.5 m true width)

• Drillhole # 2203 - 6.1 metres at 13.1 g/t Au from 111.3 metres depth (6.0 m true width)

(Including 3.0 metres at 17.3 g/t Au)

The following long section ( Figure 1 ) illustrates the new intersections juxtaposed against existing drill results as well as the

processing results from earlier mining campaigns undertaken at the Golden Jubilee Mine.

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 (Table 1* ). The Company was fully funded to complete this program and has

funds available to undertake follow up additional work. The mineralization has been intersected down dip 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 hanging wall of the targeted Golden Jubilee mineralized structure. These outcomes provide encouragement to

undertake more drilling in order 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 operatin g permits with the re levant government dep artments. 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 marbleised 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 Gol den

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 CEO of Transatlantic Mining.

About Golden Jubilee

The 22 Golden Jubilee claims (Figure 2) are situated in Granite County, Montana USA and have had a number of previous owners.

There has been only limited exploration and mining on the regional Red Lion (vein) Line trend, which is known to continue over a

regional strike of 7 km 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. Table 2 contains the results

from a bulk sample taken in 2000 and the more recent 10,000 t 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 minerali sation and vein had been observed

to be approximately 2.5 m wide with a n 80-degree dip. Enrichments and wider min eralisation widths have been observed on

geological cross structures striking at an obtuse angle to the Red Lion vein trend.

Aslam Awan PhD MAusIMM (CP Geo) is the Qualified Person pursuant to National Instrument 43 -101 for

having reviewed, only the technical information contained in this news release. Mr Awan is the Principal for

AAA GeoConsultants :

(*)The new reverse circulation drill samples were crushed in whole to plus 70 % passing 2 mm and then split

and pulverised with analysis for gold and silver at the Christofferson Laboratory, Smelterville, Idaho USA. The

Laboratory is an independent assay and umpire laboratory that follows industry techniques with blanks and

standards inserted on batches of 25. The samples being pulverised and analysed 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

mineralisation at 1.0 g/t Au cutoff ( Table 1). Table 3 are 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.
