VANCOUVER, April 5, 2017 /CNW/ - Transatlantic
Mining Corp. (the "Company") (TCO:TSX.V) announces that it has
developed a third batch of concentrate from its Advanced Property,
the Alder Gulch Property-US Grant Mine & Mill Complex located
in the Virginia City Mining District of Madison County, Montana (USA). This
report includes updates to the provisional results for the second
and third batches of concentrate going to a third party smelter.
Increasing grades are now being encountered in the US Grant Mine
between the 3 Level and 4 Level and upgrades to the 150 tpd (tons
per day) Process Plant capacity are near complete. Of note are the
following;
- The provisional assays for the third batch of concentrate
are 8.5 dmt @3.9 Oz/t Au and 157.4 Oz/t Ag;
- This represents both a 22%increase on the Gold (Au) content
and the Silver content (Ag)
- Development below 3 level confirmed grades to 13 g/t Au and
522 g/at Ag (19.9 g/t Au Equiv);
Processing
Whilst a Production Decision is still to be made, the
concentrate developed from the trial mining and processing through
the installed and commissioned 150 tpd capacity Alder Gulch Mill
has commenced for further evaluation.
The mill now has the capacity to increase concentrate yield at a
steady rate of over one tonne per day. This represents a
significant increase from the 0.6 to 0.8 tpd (tons per day)
achieved prior to the upgrade when the mill throughput was less
than 40 tpd (News Release March
1st 2017) on this trial mining phase.

Mine development below the existing 3 Level continues in
sulphide mineralisation. This material has commenced to develop a
new and third batch of concentrate with provisional assays
tabulated in Table 2. There is additional concentrate in storage
pending the return of those provisional assay results. There is
also a surface stockpile of additional material awaiting treatment.
The provisional results in Table 2 show an increase of 22 % in both
the gold and silver grades (vs Second Batch) .

The last two tonnes developed from Batch 3, were assayed at
grades of 4.9 Oz /t Au and 204 Oz/t Ag respectively. In addition,
to the 8.5 tonnes in Table 2, there are three new tonnes of
concentrate awaiting assay to be composited to Batch 3 on
receipt.
The surface stockpile of mineralised material at US Grant has
now increased from the trial processing through the 150 tpd milling
facility. Further mineralised material is expected to be delivered
from the development below the 3 Level to evaluate mining
technique, processing and recovery opportunities.
The final revenue will be subject to the final smelter receipts
and costs.
Mine Development Grades Below 3 Level
The trial mine development continues below the 3 Level with vein
grades up to 13 g/t Au and 522 g/t Ag for a 19.9 g/t Au Equivalent
over an average 0.7 m true width and over 10 metres in strike
length

This confirms that mineralisation continues below Hole
DDH_1125-13 (See News release January
19th Figure 1) with strong sulphide
mineralisation which can be observed to continue into the floor of
the 4 level exploratory mine development.
CEO Bernie Sostak
commented,
"Whilst we are in a trial mining phase, with continued staged
upgrades to the mine and mill, the results support towards a future
production decision and mine life with cashflow. The Company
continues to de-risk the current deposit with increasing knowledge.
This in addition to exploration upside also supports towards a
stronger business and investment case going forward at a new gold
and silver mine."
