Kerr Mines confirms new mineralized 'Footwall' zone at Copperstone Project

TORONTO, Oct. 24, 2017 /CNW/ - Kerr Mines Inc. ("Kerr" or the "Company") (TSX: KER, OTC: KERMF, FRA: 7AZ1) is pleased to announce the discovery of a new mineralized zone at the Copperstone Project. The newly realized Footwall Zone has been established as a mineralized zone by combining the drilling results of the 2017 Phase one surface exploration program with historical drilling results.

• The new Footwall Zone is currently 500 feet along strike by 800 feet along dip and parallel to the Copperstone Zone.
• The Copperstone Zone has a strike length greater than 4,500 feet.
• Select intervals include:
• CSR-143 is 30 feet at 11.7 g/tonne
• DCU-8 is 15 feet at 22.1 g/tonne
• KER-15-02 is 6 feet at 13.9 g/tonne
• KER-17S-04 is 12 feet at 7.3 g/tonne
• Provides a pathway to increase gold resources at the Copperstone Project.
• Footwall Zone open for expansion along strike and dip.

"Establishing the Footwall Zone is a fundamental step forward towards achieving our long term strategic growth vision. The Footwall Zone represents a significant opportunity expand our resource growth profile," said Claudio Ciavarella, CEO Kerr Mines.

Over 60 drill holes were compiled, and mineralized intervals were grouped and composited to form grade shells in this new Footwall Zone. The grade shells of historic origin were identified and combined with new grade shells formed by the phase one drill program to establish a zone of continuity.

The Footwall Zone provides a focused area within which to continue exploration drilling efforts with the goal of adding to the Copperstone Project gold resources. In addition, the discovery of this Footwall Zone allows a more focused allocation of exploration drilling outside of the Footwall Zone with the goal of expanding it along strike and dip.

The geology, including lithology, alteration and inclination, is the same as the Copperstone Zone.  The mineralized areas include intersections of quartz latite porphyry in the detachment fault brecciated sediments with chlorite and hematite alteration. 

The Footwall Zone is a parallel system to the west side of the Copperstone Zone, which historically produced over 500,000 ounces of gold and has a current mineral resource of 313,000 ounces at 10.35 gram per tonne (0.302 ounce per ton) (measured + indicated), estimated in 2010*.

About Kerr Mines Inc.
Kerr Mines is a North American gold development and exploration company currently advancing the 100% owned, fully permitted past-producing Copperstone Mine project. Copperstone is a high-grade gold project located along a detachment fault mineral belt in mining-friendly Arizona. The project demonstrates significant upside exploration potential within a 4,775 hectare (11,800 acres) land package that includes a production history of over 500,000 ounces of gold. The Company's current focus is on maximizing Copperstone's potential by defining and expanding current resources and strengthening the mine's economics leading to a production decision.

Quality Assurance and Quality Control Statement
Procedures have been implemented to assure Quality Assurance Quality Control (QAQC) of drill hole assaying being done at American Assay Laboratories (American), which is ISO Accredited.  All portions of drill holes are being assayed and samples are securely stored for shipment to American, with chain of custody documentation through delivery. Mineralized commercial reference standards and coarse blank standards are inserted every 20^th sample in sequence and results are graphed to assure acceptable results, resulting in high confidence of the drill hole assay results.  When laboratory assays are received, the QAQC results are immediately evaluated and graphed to analyze dependability of the drill hole assays. As the Copperstone Project advances, additional QAQC measures will be implemented including 1) selected duplicate assaying being done at a second accredited assay laboratory, 2) duplicate assaying of selected intervals of core (quarter splits) and reverse circulation drilling samples, and 3) metallic screen assays of selected remaining laboratory rejects. All results will be analyzed for consistency. 

*Mineral Resource Tabulation – Model capped at 5.0 oz Au/t with a 0.15 oz Au/t cutoff grade,   1,038,000 tons (measured + indicated) - NI 43-101 Technical Feasibility Report, Copperstone Project, February 11, 2010. Limited mining of this resource occurred in the period between Q4 2012 and Q3 2013 and updated tons will be tabulated when a new resource is estimated in early 2018.
