Transatlantic Mining Corporation Sampling on Upper Level averages 9.57 g/t Au and 34.7 g/t

Silver over 1.2 m true width at the Miller Mine Gold Project.

TCO NEWS RELEASE-VANCOUVER, B.C., August 17, 2020 – Transatlantic Mining Corp. (the “Company”) (TCO:TSX.V)

is pleased to announce that it has continued and extended its activities on an agreement to lease and purchase the Miller Mine in the

Broadwater County in the State of Montana , USA . Following on from Lower Level sampling previous , access was made to the

Upper Level with quartz and sulphide apparent over 100 metres ( 300 Feet) in strike. A grab sample under a collapsed chute further

informed gold mineralization on the Upper Level. The sampling both from the current program and historical mining and drill

programs underpin further drilling and future sampling activities to build a near term trial mining sample. These claims are

approximately 29 miles to the North east of Townsend in Montana and add towards the consolidation strategy of the district that

Transatlantic is undertaking.

Highlights

Upper Level

• Vein rock chip channel samples (5) average 9.57 g/t and 34.7 g/t (*) silver ( 1.2 m average width)

• Vein Length composite average over 100 m (300 feet) exposed length weighted

• Chute rock remnant grab sample assayed 12.79 g/t Au and 50 .7 g/t Ag(*)

(Grab samples are selected samples and are not representative of the mineralization hosted on the property)

Lower Level

• Grab sample on Lower Level indicate both visible gold and 15.5 g/t Au with 26 g/t Ag (**)

(Grab samples are selected samples and are not representative of the mineralization hosted on the property)

• Plan to commence access and drilling in September 2020

JG Level

• “Historical Drillholes” DD 1 and DD 2 drilled in 1968-69 (***).

Jericho DD # 1 8 feet at 14.9 oz /ton Au (2.4 metres at 516 g/t Au ).

Jericho DD #2 5 feet at 0.25 oz/ton Au (1.5 metres at 8.6 g/t Au) and

2 feet at 0.9 oz/ton Au (0.6 m at 31 g/t Au)

Key components- Upper Level Samples :

Transatlantic has taken additional reconnaissance samples, after accessing into the upper level of the Miller Gold Mine. The new

samples on entering the Upper Level exposed a 100 metre ( 300 feet) length of quartz vein and sulphide exposed in the ribs and

walls of the historical mine development .This finding and composite length assay weighted result averaged 9.57 g/t Au and 34.7

g/t Ag over a 1.2 m true width on observed strike from 5 samples on the vein strike . Based on the results , additional planning to

undertake work at the Miller Mine Patented and Unpatented claims in the Broadwater County, Montana USA is in progress. In

addition to the vein rib samples one sample was also taken of the remnant mined rock from the existing in situ underground

chutes, informing an assay of 12.79 g/t Au and 50.7 g/t Ag (*).

The compilation of existing reports with first time access to the Upper Level and with the recent Lower Level samples with

geology underpin the effort to access and plan drilling for extensions down dip and along strike . Figure 1 below is a summary to

date of the new information compiled with samples from the Lower and Upper Levels.

The following samples came from the 6300 Feet Level as a rock grab and sample 2 is one of the rib samples taken on the Upper

Level (6350 Feet level). The samples may not represent the total strike length of mineralization but are indicative of containing

gold and silver that had been previously mined historically.

The Company plans to drill on the existing exploration drill permits in the September quarter . This historical hole was

conducted by Jericho Mines Ltd in 1968-69 ( *** Table 3 ) as reported by Hemsworth July 2 1969.

About the Miller Mine and Claim Group:

Transatlantic continues the due diligence period with further collection and review of data.

The Miller Mine is situated amongst patented and unpatented claims at an elevation of 6,400 feet and accessible by roads 50 m iles

from Helena, Montana USA.

The gold and silver mineralization generally occurs on the contacts of sediments and intrusives with native gold and sulphides

including pyrite often observed with 4 underground adits ( 2 collapsed) located on the property.

“The grades and observations to date continue to support that gold exists in the mine on multiple levels. With existing

development in place ,ready access can be made to extend the known mineralization with additional drill and mine information

for future progress. ” commented Bernie Sostak CEO of Transatlantic Mining.

Key components to the Exclusive Option :

- Due Diligence extended to October 2020

- A First Renewal Term of twenty four (24) months following the expiry of the due diligence period for consideration

of $100,000 in cash or share equivalent between 5 and 10 cents CAD at Transatlantic mining election subject to

TSX approval. On that election should it occur ,Transatlantic to spend $100,000 in the first renewal term.

- A Second Renewal term of twenty four (24)months on the expiry of the First Renewal Term for consideration of

$100,000 with a minimum $100,000 spend in that period.

- Should mining occur at anytime, there will be an 8.5 % payment royalty on ounces produced until the cumulat ive

lease reaches $4.5 Million USD in payment royalty for change in ownership to 100 % Transatlantic and a perpetual

1% gold NSR to the vendor thereafter.

(*)The new rock chip samples from the Upper Level were crushed and pulverised with analysis for gold and

silver at the Christofferson Laboratory, Smelterville, Idaho USA. The laboratory is an independent assay and

umpire laboratory follows industry technique on crushing the sample and pulverised with a 30 gram fire assay

charge to assay with a gravimetric finish and observed in the laboratory report . ( Note : Table 1)

(***)The technical data is based on the written historical reports as stated with no availability of the core/pulps to

currently validate the historical data for the diamond drilling. (**)The grab samples from the Lower Level (6300

Ft) was analysed and tested for gold and silver using a 50 gram fire assay charge with a gravimetric finish at

IAL(34 Buckingham Drive Wangara West Australia independent assay laboratory following standard industry

crushing and pulverising technique. (Note Table 2, table 3)
