Kerr Mines increases down dip extension of Copperstone D Zone with 60.5 feet @ 27.0 g/t Au

TORONTO, Dec. 5, 2017 /PRNewswire/ - Kerr Mines Inc. (TSX: KER, OTC: KERMF, FRA: 7AZ1) ("Kerr" or the "Company") is pleased to announce further results of its Phase I drilling program. KER-17U-12 interval of 32.0 feet @ 16.0 g/t Au has been extended by 28.5 feet @ 39.1 g/t Au for a final total interval length of 60.5 feet @ 27.0 g/t Au (see press release dated November 2, 2017). Phase I of the program continues to confirm significant gold mineralization and increases the confidence in expanding the resource at the Company's Copperstone project in Arizona.

Highlights

• New intervals drilled from underground through the Coppertone Zone include:
• 28.5 feet @ 39.1 g/t Au (KER-17U-12)
• 10.5 feet @ 8.8 g/t Au (KER-17U-13)
• 28.8 feet @ 38.6 g/t Au (KER-17U-14)
• 14.5 feet @10.9 g/t Au (KER-17U-16)
• 12 feet @ 6.7 g/t Au (KER-17S-01)
• Results continue to extend down-dip and up-dip gold grade and extend mineralized areas along strike in the Copperstone Zone
• Drill hole spacing designed to upgrade resources from inferred to measured and indicated

Martin Kostuik, President, stated, "these continuing achievements support the confidence we have in developing this resource to its fullest potential. Attributes of high grade and continuity are regularly displayed in the drilling results"

The Copperstone Zone detachment fault system historically produced over 500,000 ounces of gold from an open pit. Continuing below the open pit, the down-dip extension of the Copperstone Zone has an undiluted mineral resource of 313,000 oz Au at 10.35 g/t Au (0.302 ounce per ton)-(311,000 measured + 2000indicated), estimated in 2010* which is being further enhanced by the Phase 1 drilling program. The Phase I 15,000 feet underground program is currently using three drills to test along strike and up/down-dip in the D and C portions of the Copperstone Zone. The program is confirming mineralized detachment fault breccia continuity from existing underground workings at depths from 100 to 400 feet below the open pit bottom.

KER-17U-12 was drilled in the northwestern portion of the Copperstone Zone, starting from below and drilling towards the northeast into the Copperstone Zone. This hole was designed to confirm previous results and had total updated results of 71 feet @ 23.1 g/t Au. Important silicic and hematitic alterations including magnetite replacement were encountered. These strong results will potentially increase the size and grade of the historic mineralized zone.  

KER-17U-13 was drilled from below and towards the Copperstone Zone. KER-17U-13 is a confirmation hole ending 140 feet to the south of KER-17U-12. The results of this hole confirm historical results and also improve continuity in a sparsely explored area with the best intercept of 10.5 feet @ 8.8 g/t Au and 0.41% copper (Cu). The beginning of the mineralized portion of this hole is only 45 feet from existing workings.

KER-17U-14  was drilled from below towards the northeast and tests the down dip extension of the Copperstone Zone. KER-17U14 is designed to upgrade resources and demonstrate continuity.  It also increases the dimensions of the mineralized lens in this area with high grade intercepts in two locations. This hole is 70 feet from each of KER-17U-12 and KER-17U-13 and displays an over-all interval of 88 feet @ 13.9 g/t Au. Limestone, skarn, sandstone and siltstone were encountered-with limestone becoming important to the understanding of mineral deposition. This interval has intercepts as high as 28.8 feet @ 38.6 g/t Au.

KER-17U-16 was drilled from below the Copperstone Zone but upward towards the northwest to test and confirm the up dip potential of the Copperstone Zone. KER-17U-16 tests the up dip potential of the Copperstone Zone by confirming historic results and extending the mineralized lens along dip. The overall interval of 105 feet @ 4 g/t Au included several high grade intercepts ranging from 7.7 g/t Au to 10.9 g/t Au and as high as 0.99% Cu to help define this zone. Important units of limestone and alteration including silica and hematite were encountered. The overall average grade of Cu for this 105 foot interval is 0.29%.

KER-17S-01 was drilled from the surface and vertically down into the Copperstone A Zone. KER-17S-01 tests the down dip potential of the Copperstone A Zone. An overall interval of 17 feet @ 4.8 g/t Au included a high grade interval of 7.6 feet @ 10.5 g/t Au. Important silicic and hematitic alteration was encountered in the Copperstone breccia. The results in KER-17S-01 are approximately 200 feet down dip and east of historic drill results and extend the known Copperstone A Zone mineralization by approximately 85 feet down dip while also serving to extend mineralization along strike.

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.
