TRANSATLANTIC MINING -NI 43-101 AND PRELIMINARY ECONOMIC

ASSESSMENT

ALDER GULCH PROJECT – US GRANT MINE

12th December 2016 TSX Venture Exchange

Trading Symbol: TCO

Vancouver, British Columbia

Transatlantic Mining Corp. (“TCO” or the “Company”) (TSX-V: TCO) is pleased to provide the following

update to investors.

Highlights

 A NI 43-101 and Preliminary Economic Assessment

 Maiden Mineral Resource of 53,800 Gold Equivalent Ounces

 A Preliminary Economic Assessment with All-In Sustaining Cost of $905 /Oz Au equivalent

 An estimated Internal Rate of Return of 272%

 An Exploration Target of 500Koz Gold Equivalent Ounces

Summary

The US Grant Mine is a group of patented and unpatented claims within the Alder Mountain Project. The Alder

Mountain Project property comprises a 535 acre total land package with 5 patented and 28 unpatented claims

located in the Virginia City Mining District of Madison County, Montana.

As original ly announced January 22, 2016, the Company has an exclusive Option and Lease to Purchase

Agreement with the current owners, Madison Mining Corporation and Elite Properties, for the US Grant Mine and

Alder Mountain Project. This agreement commenced effective January 18, 2016. On completion of the terms of

this agreement, TCO, at its election within the 16 month (4 month due diligence and 12 month lease) period, can

earn 100% ownership on election to purchase. TCO can also utilize all plant and equipment within the lease

period with that processing benefit direct to the TCO account.

The Company has now received a National Instrument 43-101 (NI 43-101) Standards of Disclosure for Mineral

Projects compliant resource estimation and Preliminary Economic Assessment (PEA) for the patented portion of

the US Grant Mine property. This is based predominantly on historical information and recent TCO sampling of

accessible US Grant Mine workings (the “Report”). The Report was authored by Chris Pfahl, PE, PLS, who is a

Qualified Person under NI 43-101 and has revie wed and approved the disclosure of a scientific or technical

nature herein.

All required permits have been secured for the PEA activities at the US Grant Mine property. The current Small

Miner’s Exclusion Statement permit #25-221 allows for up to five acres of disturbance. No additional permitting

from the Montana DEQ is necessary at this time.

Maiden NI 43-101 Mineral Resource

The following table represents the current maiden NI 43 -101 mineral resource for the US Grant Mine property

based on mapping and sampling information as at June 30, 2016. The following figure illustrates the mineral

resource outline and mine design used for the PEA.

Preliminary Economic Assessment (PEA)

This PEA has been developed based on the mineral resource as described in the Table 1. The current levels of

mineral resource do not demonstrate economic viability or a mineral reserve. Unless otherwise stated, all cost

estimates in this PEA are reported in United State Dollars.

Figure 1 : A Schematic Long Section covering the US Grant Vein and Design

The 3.6 year life-of-mine (LOM) has estimated total capital costs of $8.8 M.

The Life of Mine operating costs are $18.2 M as detailed in the following table.

Table 2: The US Grant Vein Life of Mine Operating Costs

The base case financial model for the US Grant Mine property is estimated to have an after-tax internal rate of

return (IRR) of 2 78% with payback occurring at approximately 16 months from commencing operations with

allocated funding.

The following table summarizes a base-case net present value (NPV) with various discount rates which also

incorporates the purchase price of the US Grant Mine property of $6M within that model. The gross revenue is

based on a gold price of $1350 and a silver price of $19 and on the US Grant Vein only. Exploration upside could

exist outside this initial assessment.

The All-in-sustaining-costs ( AISC) are estimated at $ 905 per equivalent gold ounce on the current

assessment without any upside or full conversion of the inferred mineral resource contained above.

Exploration Opportunity

The US Grant Mine property has had only a limited amount of historical exploration drilling during its time. The

mineral resource and cost estimates within this PEA include a portion of the US Grant vein without the addition

of any future exploration potential on other veins or opportunities within the greater Alder Mountain Project. An

exploration target of approximately 500,000 gold equivalent ounces has been planned to be drill tested of which

the full expenditure has not been allowed for and is outside the scope of the PEA and Mineral resource outlined

above. The fund allocation within the PEA only supports drilling to upgrade the confidence levels in the Mineral

Resource and subsequent decision to purchase the Alder Mountain Asset . It is the opinion of the author of the

NI 43-101 Report that the US Grant Mine property has not been adequately explored. S urface drilling targeted

the vein system to less than 300 feet below the surface from three locations. Underground drilling targeted the

vein system less than 100 feet below the US Grant Mine #3 level and only provided a cursory look for additional

vein systems in the hangingwall and footwall of the US Grant vein.

The author recommends both surface and underground drill programs to increase the resource base of the US

Grant Mine property. The intercept in drill hole USG-88-2 is open along strike and down dip. The well-developed

road system at the property provides access to offset drill this intercept. The US Grant Mine #3 level should be

extended approximately 1,800 feet to the southwest end line of the property and the vein developed where grade

and widths indicate the potential for resource expansion and extension. Drilling to optimise the mine design and

current capital infrastructure to the limit of the claim block to identify additional mineralized structures are

warranted.

Economic Assessment at the US Grant Mine Property, Virginia City, Madison County, USA ” Transatlantic

requested Chris Pfahl to prepare the Technical report. Mr Pfahl is a “Qualified Person” as defined in NI 43 -101
