Third Quarter Production and Sales Update

Acacia notes Barrick Gold Corporation’s (“Barrick”) announcement yesterday evening that it would be publishing its third quarter production and sales results, which will include Barrick’s 63.9% share of Acacia’s operations, later today. Ahead of that release Acacia confirms that it produced 191,203 ounces of gold and sold 132,787 ounces of gold during the third quarter.

Production was ahead of expectations at Buzwagi (69,097 ounces), driven by strong grades, with production at North Mara (72,011 ounces) and Bulyanhulu (50,094 ounces) impacted, as previously flagged, by work permit issues and moving to reduced operations respectively. Sales were below production due to the ban on the export of gold/copper concentrate produced at Bulyanhulu and Buzwagi from Tanzania.

Acacia will provide more details within our third quarter results on the 20^th October 2017. The results will be accompanied by a conference call for investors and analysts at 09:00 BST on the same day.

The access details for the conference call are as follows:
