Gran Colombia Gold Increases Interest in Sandspring Resources to Approximately 19.96%

TORONTO, June 12, 2019 - Gran Colombia Gold Corp. (TSX: GCM, OTCQX: TPRFF) announced today that has increased its equity position in Sandspring Resources Ltd. (“Sandspring”) (TSX-V: SSP, OTCQX: SSPXF) to 19.96% through a non-brokered private placement (the “Private Placement”) completed today by Sandspring. Sandspring intends to use the proceeds of the Private Placement to continue work on the re-scoping of the Toroparu Project, additional exploration at its Chicharron Project and for general working capital. On June 4, 2019, Sandspring announced positive results of a preliminary economic assessment for its Toroparu Project and the next stage of development will encompass completion of a feasibility study for the project.

Sandspring’s Private Placement comprised a total of 26,801,000 units (each, a “Unit”), and 5,200,000 subscription receipts (each, a “Receipt”), at a price CA$0.125 per Unit and Receipt, for gross proceeds of CA$4.0 million. Each Unit issued in the Private Placement consists of one common share and one share purchase warrant entitling the holder to purchase one additional share at CA$0.165 for a period of sixty (60) months. The placement was fully subscribed and included an investment from the Company in the amount of CA$2.0 million.

The Receipts were issued to the Company as part of its participation in the Private Placement. Each Receipt will automatically convert into a Unit upon Sandspring receiving shareholder approval for the creation of the Company as a “control person” of Sandspring, being a holder of greater than 20% of the voting rights of Sandspring’s outstanding securities. In the event the Receipts have not converted into Units prior to December 31, 2019, the Company will be entitled to a refund of the proceeds received from the Receipts in the amount of $650,000, along with interest at the rate of 5% per annum. Sandspring intends to seek shareholder approval for the creation of the Company as a “control person” at its annual general meeting to be held later in the year.

Through completion of the Private Placement, the Company has increased its holdings in Sandspring to an aggregate of 48,300,000 common shares, 26,800,000 share purchase warrants and 5,200,000 Receipts. The common shares controlled by the Company represent approximately 19.96% of the outstanding common shares of Sandspring. Assuming conversion of the Receipts and exercise of the underlying warrants, the Company, when combined with its existing ownership, would have control and direction over 85,500,000 common shares representing approximately 30.66% of the then outstanding common shares of Sandspring. The Company can potentially become a “control person” of Sandspring assuming conversion of the Receipts or the exercise of share purchase warrants and have undertaken not to exercise the warrants if such conversion would result in them becoming a control person of Sandspring, unless and until shareholder approval (excluding the Company’s votes) has been received.

The additional shares, warrants and Receipts were acquired for investment purposes and the Company has no present intention to dispose of or acquire further securities of Sandspring, although the Company may in the future acquire or dispose of securities of Sandspring, through the market, privately or otherwise, as circumstances or market conditions warrant.
