TRANSATLANTIC MINING CORP. CONCENTRATE READY FOR REVENUE AT ALDER GULCH-US GRANT MINE & MILL COMPLEX, MONTANA (USA)

Transatlantic Mining Corp. has presold its second concentrate batch from the Alder Gulch property/U.S. Grant mine and mill complex located in the Virginia City mining district of Madison county, Montana, United States. This report contains the provisional results for this second concentrate batch set for a third party smelter, along with final results from the first low-grade concentrate 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 dry metric tonnes of 3.08 ounces per ton gold and 118 ounces per ton silver.
• This represents a 10-per-cent increase on the gold content and a 112-per-cent increase on silver content compared with the first batch.

Results from the first batch of concentrate are shown in an attached table. This lower-grade concentrate was derived from low-grade mineralization and was announced on Jan. 19, 2017. The results demonstrate that plant-scale gold and silver recovery is higher than indicated by the metallurgical test work reported in the recent National Instrument 43-101 report for the U.S. Grant mine and mill complex.

                  FIRST BATCH OF CONCENTRATE RESULTS 

Dry tonnes      Ounces      Contained     Metal recovery     Recovered 
               per ton    troy ounces                      troy ounces

16.8           2.79 Au        45.6 Au              97.7%       44.6 Au
16.8           55.7 Ag       933.7 Ag              91.9%      857.9 Ag

All of the gold and silver concentrate was produced by the 40-tonne-per-day U.S. Grant mill. The rate of concentrate production has steadily increased to a rate of 0.6 ton per day to 0.8 tonne per day as higher proportions of sulphides are appearing in the mineralized rock being delivered from the mine.

New mine development below the existing level 3 has yielded the mineralized rock used to produce the second batch of concentrates. The provisional results are shown in an attached table.

The final revenue will be subject to the final smelter receipts and costs. There are a further nine wet tonnes of mineralized concentrate stockpiled at U.S. Grant, which will be sold when assays have been received.

The mineralized surface stockpile at U.S. Grant now has a further 400 mined tonnes available for processing. Further higher-grade material is expected to be delivered from the development below level 3.

Process plant up to 150-tonne-per-day status

The 150-tonne-per-day 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-tonne-per-day mill rate, with any of the incremental mining rate above that level intended toward this increased mill capacity.

Bernie Sostak, chief executive officer of Transatlantic Mining, 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 cash flow going forward."
