Kerr Mines Inc. (TSX: KER, OTC: KERMF), ("Kerr" or the "Company"), is pleased to provide an update on recent positive developments on receipt of a Decision of Record at its 100% owned Copperstone Mine gold project located in Arizona, USA.

On December 17, 2019 the U.S. Bureau of Land Management ("BLM") closed the Environmental Assessment ("EA") Notice period in support of the Mine Plan of Operation ("MPO") for the Copperstone Project. As there were no comments, the published EA is being accepted as written. Accordingly, the next and final step in the process is for the BLM to issue a Decision of Record ("DOR") based on a Finding of No Significant Impact ("FONSI") and formally approving the modification to the existing MPO at Kerr's Copperstone Mine gold project.

Kerr expects the receipt of the DOR based on FONSI and approved MPO in the coming weeks resulting in the following positive project implications:

-- Increase of gold ore production from the current allowable limit of 450 tons per day to 600 tons per day;

-- Use of cyanide for recovery of gold from ore using captive steel tanks located in the gold ore processing facility;

-- Storage of stabilized tailings produced from the ore processing facility;

-- Construction and use of a water evaporation and infiltration basin to be used to manage surplus water generated from underground operations; and,

-- Improved operating conditions which will further improve project economics.

All other permits required for mine operations and gold production are currently in hand and do not require further modification.

Giulio T. Bonifacio, Chief Executive Officer stated: "We are extremely pleased with recent developments on the permitting front which is now nearing completion. Final receipt of the Decision of Record will prove to be a significant project milestone as it will allow Kerr to advance Copperstone to production on a basis that further enhances project economics"
