Kerr Mines drills 32 feet @ 16.2 g/t gold and extends Copperstone Zone along strike and depth
TORONTO, Nov. 2, 2017 /CNW/ - Kerr Mines Inc. (TSX: KER, OTC: KERMF, FRA: 7AZ1) ("Kerr" or the "Company") is pleased to announce initial results of its Phase I underground drilling program with 10 of 12 drill holes intersecting significant gold mineralization and increasing the confidence in expanding the resource at the Company's Copperstone project in Arizona.
Highlights
- Results extend down-dip and up-dip gold grade and extend mineralized areas along strike in 2 sections of the Copperstone Zone
- Historical drilling results confirmed
- New intervals drilled from underground through the D Zone include:
- 32 feet @ 16.2 g/t Au (KER-17U-12)
- 20 feet @ 8.6 g/t Au (KER-17U-06)
- 15 feet @ 5.1 g/t Au (KER-17U-04)
- 10 feet @ 7.9 g/t Au (KER-17U-05)
- 13 feet @ 6.2 g/t Au (KER-17U-11) and
- 9 feet @ 5.4 g/t Au (KER-17U-11)
Martin Kostuik, President, stated, "with these initial Copperstone Zone results and the previously announced Footwall Zone results, (see press release dated 24 October 2017), we remain confident in delivering on our target of producing an updated resource estimate under NI 43-101 guidelines and delivering a Prefeasibility study in Q1 2018."
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 a mineral resource of 313,000 oz Au at 10.35 g/t Au (0.302 ounce per ton) (measured + indicated), estimated in 2010* is being further enhanced by the Phase 1 underground drilling program. The Phase I 15,000 feet underground program is currently using two drills to test along strike and up/down-dip in the D and C zones of the Copperstone Zone. The program is confirming altered detachment fault breccia continuity from existing underground workings at depths from 100 to 400 feet below the open pit bottom.

KER-17U-04 was designed to explore the down-dip extension of the Copperstone Zone and resulted in an intercept of 15 feet @ 5.1 g/t Au. This complements the historic results shown by DU4-41, CUDH-04-25 and CUDH-04-26 by extending D zone mineralization down-dip by approximately 75 feet, and confirms continuity along strike.
KER-17U-05 was designed to test continuity between two historic holes and resulted in an intercept of 10 feet @ 7.9 g/t Au. This confirms historic intercepts along strike in D zone mineralization previously indicated by CUDH-04-25, and DU4-41, and extends intervals down dip by approximately 35 feet.
KER-17U-06 was designed to both confirm an historic drill hole interval and test an area between two historic holes. This resulted in two separate intervals of 20 feet @ 8.6 g/t Au and 21 feet @ 3.1 g/t Au. The first interval confirms continuity of grades and thickness along strike as it intersects an area between intervals reported in DU4-41 and CUDH-04-25. The second interval reported confirms continuity in a lower lens of D zone mineralization defined by intercepts in CUDH-04-26.
650 Access
KER-17U-08 was designed to test the up-dip extension of this portion of the D zone and resulted in an intercept of 7.1 feet @ 4.8 g/t Au. This result is encouraging as it provides new up-dip potential of this area which has existing access for mining.
KER-17U-11 was a zone confirmation hole and was intended to fill an area between historic holes and resulted two intercepts of 13 feet @ 6.2 g/t Au. and 9 feet @ 5.4 g/t Au. The first interval is 140 feet from the that reported in DU4-51, extending continuity of Copperstone mineralization in the D zone along strike by 30 feet. In addition, the second interval is 60 feet from that reported in DU5-64, and confirms down-dip continuity of D zone mineralization in the Copperstone Zone.
KER-17U-12 was designed to confirm previous results and resulted in 32 feet @ 16.2 g/t Au while increasing the historic zone. This interval is 15 feet from and confirms the grade results reported in DU5-64. In addition, it confirms down dip continuity of D zone mineralization being 115 feet from reported intervals in DU4-51. Furthermore, it confirms continuity along strike being 75 feet from reported intervals in DU5-56.

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 20th 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.

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.
