EURO Ressources completes the silver stream transaction with Orezone Gold

The Silver Stream entitles EURO to receive 50% of the payable silver production over the life of mine on Orezone's Bombor? Project ("Bombor?"), located in Burkina Faso, West Africa. The Silver Stream also stipulates a minimum guaranteed delivery obligation in favour of EURO of 37,500 ounces of silver per annum, until delivery of 375,000 ounces of payable silver.

Full details of the transaction can be found in EURO's news release dated March 1, 2021.

The Bombor? Project

Orezone Gold Corporation (TSX.V: ORE OTCQX: ORZCF) is a Canadian development company which owns a 90% interest in Bombor?, one of the largest undeveloped gold deposits in Burkina Faso. The 2019 feasibility study highlights Bombor? as an attractive shovel-ready gold project with forecasted annual gold production of 118,000 ounces over a 13+ year mine life at an AISC of US$730/ounce with an after-tax payback period of 2.5 years at an assumed gold price of US$1,300/ounce. Assay data and metallurgical studies suggest there is a silver component to the Bombor? deposit, with EURO's review of assay data indicating that the average silver grade is in the region of 1 g/t and that the silver to gold ratio is approximately 1:1. Bombor? is underpinned by a mineral resource base in excess of 5 million ounces of gold and possesses significant expansion potential.

Orezone plans to develop Bombor? in two stages: Stage 1 is focused on the Free Dig Oxides as a CIL operation with no crushing and minimal grinding with average recoveries of 87%; and Stage 2 will focus on the underlying higher-grade sulphides with a separate crushing and grinding circuit feeding the same CIL circuit as the oxides. This will reduce upfront capital and increase annual production and recovered ounces over the life of mine.
