Transatlantic Mining Corp. Concentrate Ready for Revenue
       At Alder Gulch-US Grant Mine & Mill Complex, Montana (USA)
   TCO NEWS RELEASE-VANCOUVER, B.C., February26th, 2017 - Transatlantic Mining Corp. (the "Company") (TCO:TSX.V) annou
--->nces that it has pre sold its second concentrate batch from the Alder Gulch Property-US Grant Mine & Mill Complex loca
--->ted in the Virginia City Mining District of Madison County, Montana (USA).  This report contains the provisional resul
--->ts for this second concentrate batch set for a third party smelter along with final results from the first low grade c
--->oncentrate treated through a third party Cyanide in Leach Processing facility reported previously in January.  
Provisional Results for the second batch of concentrate:
The provisional results for the concentrate are 12.7 dmt @ 3.08 Oz/t Au and 118 oz/t Ag
This represents a 10% increase on the Gold (Au) content and a 112 % increase on silver (Ag) content compared to the fi
--->rst batch

Results from the first batch of concentrate are shown in Table 1. This lower grade concentrate was derived from low gr
--->ade mineralisation and was announced on 19th January 2017. The results demonstrate that plant scale gold and silver re
--->covery is higher than indicated by the metallurgical test work reported in the recent NI -43-101 report for the US Gra
--->nt.

All of the gold and silver concentrate was produced by the 40 ton per day US Grant mill. The rate of concentrate produ
--->ction has steadily increased to a rate of 0.6 to 0.8 tpd (tons per day) as higher proportions of sulphides are appeari
--->ng in the mineralised rock being delivered from the mine.

New mine development below the existing 3 Level has yielded the mineralised rock used to produce the second batch of c
--->oncentrates. The provisional results are shown in Table 2.

The final revenue will be subject to the final smelter receipts and costs. There is a further nine wet tonnes of miner
--->alised concentrate stockpiled at US Grant which will be sold when assays have been received.

The mineralised surface stockpile at US Grant now has a further 400 mined tonnes available for processing. Further hig
--->her grade material is expected to be delivered from the development below the 3 Level. 

Process Plant up to 150 tpd (ton per day) Status
The 150 tpd ball mill and process plant capacity is expected to be running at a steady state at the beginning of March
---> with only minor modifications incomplete. The trial mining rate is now in excess of the 40 tpd mill rate, with any of
---> the incremental mining rate above that level intended towards this increased mill capacity. 
 
CEO Bernie Sostak commented, 
"It is good news to see that the processing facilities are now running with the first steps towards consistent revenue
---> on a daily basis. The team at site now have the ability to consistently produce revenue which is a credit to all the 
--->work done over the previous 12 months. With successful exploration recently, and the mill and trial mining progressing
---> well, we now are building further confidence that the mine can be a consistent performer with cashflow going forward.
