TORONTO - Gran Colombia Gold Corp. (TSX: GCM; OTCQX: TPRFF) ('Gran Colombia') announced today the completion of its acquisition of all of the issued and outstanding common shares of Gold X Mining Corp. not already owned by Gran Colombia by way of a statutory plan of arrangement under the Business Corporations Act (British Columbia).

The Arrangement became effective at 12:01 a.m. (Pacific Time) on June 4, 2021 (the 'Effective Time'). As a result of the Arrangement, Gold X became a direct, wholly-owned subsidiary of Gran Colombia and Gran Colombia gained control of the Toroparu Gold Project located in Guyana, South America.

Serafino Iacono, Executive Chairman of Gran Colombia, commented: 'With the closing of the Gold X acquisition today, we have created a new mid-tier Latin-American gold producer with a complementary asset portfolio including the world-class, free cash flow generating Segovia Operations located in Colombia and the large, high-growth and substantially de-risked Toroparu Gold Project in Guyana. On a combined basis1 for Segovia and Toroparu, our measured and indicated gold resources now total 8,778,000 ounces (256.5 Mt grading 1.06 g/t Au) and we have another 4,359,000 ounces of gold in the inferred category (132.6 Mt grading 1.02 g/t Au). Over the next couple of months, we will be refining our development options at Toroparu, including an update of the mineral resource estimate for the Toroparu Project to incorporate the new geologic model and project optimization that includes the discovery of continuous high-grade gold bearing structures extending for at least 3 kilometers in strike and at least 450 meters in depth as recently announced by Gold X. With approximately US$6 million of cash in Gold X at closing of this acquisition, this next stage of project evaluation that will lead to an updated preliminary economic assessment for Toroparu is fully funded. We are very excited to begin this next chapter, creating value for our shareholders through our diversified growth platform centered on these two cornerstone assets and our equity positions in Aris Gold and Denarius.'

Completion of the Arrangement

Pursuant to the Arrangement, each holder of Gold X Shares is entitled to receive 0.6948 of a common share in the capital of Gran Colombia (a 'Gran Colombia Share') for each Gold X Share held immediately prior to the Effective Time, (the 'Exchange Ratio').

As of today, the Company now has 98,287,088 common shares issued and outstanding and a total of approximately 132.1 million common shares on a fully-diluted basis.

With Gold X now a wholly-owned subsidiary of Gran Colombia, Gran Colombia intends to de-list the Gold X Shares from the TSX Venture Exchange as soon as practicable. Gran Colombia also intends to submit an application to the applicable securities regulators to have Gold X cease to be a reporting issuer and terminate its public reporting obligations. Prior to the completion of the Arrangement, Gran Colombia owned, directly or indirectly, or exercised control or direction over, 9,571,158 Gold X Shares representing approximately 15% of the issued and outstanding Gold X Shares prior to the completion of the Arrangement.

In order to receive Gran Colombia Shares in exchange for Gold X Shares at the Exchange Ratio, registered shareholders of Gold X must complete, sign, date and return the letter of transmittal that was mailed to each Gold X shareholder prior to the Effective Time.

For those shareholders of Gold X whose Gold X Shares are registered in the name of a broker, investment dealer, bank, trust company, trust or other intermediary or nominee, they should contact such nominee for assistance in depositing their Gold X Shares and should follow the instructions of such intermediary or nominee.

Warrants and Options

Pursuant to the Arrangement, all stock options of Gold X (the 'Gold X Options') were accelerated and exercised prior to the Effective Time, or, if not exercised, were terminated at the Effective Time without payment of any consideration to the holders of such terminated Gold X Options.
