Gran Colombia Gold Announces Intention to Spin Off Marmato to Carry Out

Proposed Expansion of Underground Mining Operations

TORONTO, Sept. 16, 2019 -- Gran Colombia Gold Corp. (TSX: GCM; OTCQX: TPRFF) announced today that it intends to spin

off its Marmato mining assets into a separate listed special purpose vehicle. Through the spin off, Gran Colombia will retain a

major stake in the new company while leveraging the capital markets to provide the funding required for ongoing exploration

and the development of the underground mining assets at Marmato, including the expansion of operations to incorporate the

Deeps mineralization and the construction of a new processing plant and additional tailings storage facilities to support the

increased level of production.

Serafino Iacono, Executive Chairman of Gran Colombia, stated, “We are nearing completion of the underground mine

expansion study at Marmato. We expect to file a preliminary economic assessment before the end of the year and

immediately thereafter proceed with the prefeasibility study. We are excited to be in a position to see a path forward to develop

this world class deposit and to begin to get a return on investment for our shareholders. The proposed mine plan envisions the

optimization of mining activities in the upper existing mine, similar to what we did in the early stages of the turnaround at

Segovia, that will increase production and reduce cash costs starting in 2020. Concurrently, we will begin development of the

Deeps mineralization in a modern, mechanized mining operation.  In evaluating our options to fund the development of the

Deeps mineralization and construct the facilities required to support the expanded mining operations, we have carefully

considered the potential impact of any proposed financing on our current capital structure and balance sheet. We have heard

from many of our shareholders that they would not be in favour of a highly dilutive equity issue. In addition, after working so

hard the last few years to strengthen our financial liquidity, we are reluctant to add a significant amount of debt back onto our

balance sheet. We want to focus the use of our free cash flow and cash balances to further the exploration and development of

our high-grade Segovia Operations which have been the key catalyst to our successful turnaround and this year’s share price

appreciation. For these reasons, we feel a spin off of the Marmato mining assets into a separate listed special purpose vehicle

allows us to retain a major stake in the Marmato Project without having an adverse impact on either our capital structure or our

balance sheet. We are in the preliminary stages of identifying the listed vehicle for this initiative and we will provide further

updates and information as it becomes available.”

Located in the Caldas department in the heart of the Middle Cauca gold district, the Marmato Project contains 40.7 million

tonnes at a grade of 2.9 g/t totalling 3.8 million ounces of gold in Measured and Indicated Resources and 52.0 million tonnes

at a grade of 2.5 g/t totalling 4.2 million ounces of gold in Inferred Resources. The existing Marmato underground mine, located

in the Zona Baja area of the Marmato mountain, is on track to produce between 24,000 and 26,000 ounces of gold in 2019.

The Marmato Project has excellent infrastructure, being located by the Pan American Highway with access to Medellin to the

north and Manizales to the south, and has access to the national electricity grid which runs near the property.
