Kerr Mines 255% increase in mineralized extents of Footwall Zone

TORONTO, ONTARIO--(Marketwired - Jan 17, 2018) - Kerr Mines Inc. (TSX:KER)(OTCQB:KERMF)(FRANKFURT:7AZ1) ("Kerr" or the "Company") is pleased to announce further results of its Phase I surface drilling program. KER-17S-21 further extends the Footwall Zone by returning a 36.6 meter drill hole interval with 7.5 g/t gold (Au) and 0.26% copper (Cu). 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 the surface through the Footwall Zone include:
  • 3.4 meters @ 7.9 g/t Au and 2.78 % Cu (KER-17S-10)
  • 4.6 meters @ 13.2 g/t Au and 1.28 % Cu (KER-17S-13)
  • 4.3 meters @ 6.8 g/t Au and 0.19 % Cu (KER-17S-17)
  • 36.6 meters @ 7.5 g/t Au and 0.26 % Cu (KER-17S-21)
• Increase of 255% of mineralized zone including an increase of 223 meters of strike and 91 meters of dip extents compared to previously announced Footwall Zone.
• Discovery of a new and separate Footwall mineralized zone with 105 meters of strike and 240 meters of dip.
• Open for further expansion along strike and dip with future drilling.

Martin Kostuik, President, stated, "the significant increase in the size of the Footwall Zone and an addition of a separate mineralized area adjacent to the same Footwall Zone is an amazing step towards increasing Kerr Mines shareholder value. With the surface program complete and underground assay results continuing to be delivered, we are excited to compile all of the 2017 exploration data and form a new Copperstone Project resource by the end of this quarter "

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 (311,00 measured + 2,000 indicated) at 10.35 g/t Au (0.302 ounce per ton), estimated in 2010* which is being further enhanced by the Phase I drilling program. The Phase I 8,000 meter surface and underground drilling program is complete with final assays pending. The Phase I program tested along strike and up/down-dip in the D and C portions of the Copperstone Zone and in the newly announced parallel Footwall Zone (see press release dated October 21, 2017).

KER-17S-10 is a vertical core hole drilled in the northwestern portion of the Footwall Zone drilled towards the southwest beneath the Copperstone shear. This hole was designed to extend the Footwall Zone and resulted in a mineralized interval of 7.5 meters @ 3.7 g/t gold and 1.36% copper. Combining gold and gold equivalent copper grades results in a total of 5.9 g/t Au equivalent (g/t AuEq) for the interval. Included in this interval is 3.4 meters @ 7.9 g/t Au and 2.78% Cu for an 12.5 g/t AuEq. Other sub-intervals of this result are in Table 1 below.

KER-17S-11 is an inclined core hole drilled in the northwestern portion of the Footwall Zone drilled towards the southwest. This hole is drilled from the same location as KER-17S-10 and is designed to add up-dip continuity to the KER-17S-10 result. Results are 3 meters @ 3.9 g/t Au and 0.16% Cu for a 4.1 g/t AuEq. This interval is 100 meters up-dip from the interval reported in KER-17S-10.

KER-17S-13 is a vertical reverse circulation (RC) hole collared in the northwestern portion of the Footwall Zone and drilled towards the southwest. KER-17S-13 is designed to upgrade resources, demonstrate continuity and resulted in a mineralized interval of 15.2 meters @ 4.6 g/t Au and 0.48% Cu for a 5.4 g/t AuEq. Included in this interval is 4.6 meters @ 13.2 g/t Au and 1.28% Cu for a 15.3 g/t AuEq. This result is 82 meters down dip of the historic 06CS-17 which contained a 3.0 meter @ 7.0 g/t Au interval. KER-17S-13 is located 125 meters along strike from KER-17S-10.

KER-17S-17 is an inclined core hole drilled in the northwestern portion of the Footwall Zone drilled towards the southwest. KER-17S-17 tests the down dip continuity of the Footwall Zone and intercepts mineralization 100 meters below the historic 06CS-17 interval of 3.0 meters @ 7.0 g/t Au. Results are 9.3 meters @ 3.6 g/t Au and 0.15% Cu for a 3.8 g/t AuEq. This interval includes 4.3 meters @ 6.8 g/t Au and 0.19% Cu for a 7.2 g/t AuEq. KER-17S-17 is located 64 meters along strike from KER-17S-10.

KER-17S-19 is a vertical reverse circulation (RC) hole collared in the northwestern portion of the Footwall Zone and drilled towards the southwest from the same location as KER-17S-04 (see press release dated October 21, 2017). KER-17S-19 tests the down dip potential of the Footwall Zone and contains two mineralized intervals which show the potential to extend the mineralized intervals down dip of KER-17S-04. The first interval is 10.7 meters @ 2.8 g/t Au and contains 3.0 meters @ 4.0 g/t Au. The second interval is 3.0 meters @ 4.6 g/t Au and is 76 meters down dip of KER-17S-04.

KER-17S-21 is an inclined reverse circulation (RC) hole collared in the southeastern extents of the Copperstone pit and drilled towards the southwest. KER-17S-21 tests the down dip continuity of the Footwall Zone and intercepts a 36.6 meter long interval of mineralization. This interval is located 73 meters down dip below the historic 06CS-18 drill hole interval of 3.0 meters @ 3.9 g/t Au. KER-17S-21 contains two mineralized intervals which extend the mineralized zone. The first interval is 3.0 meters @ 6.6 g/t Au and 0.66% Cu for a 7.7 g/t AuEq. The second interval is 36.6 meters @ 7.5 g/t Au and 0.26% Cu for a 7.9 g/t AuEq. Included in this interval are 7.6 meters @ 31.2 g/t Au and 3.0 meters @ 71.9 g/t Au. KER-17S-21 intercepts are located 85 meters from KER-17S-19 intervals.

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 (1,029,000 measured + 9,000 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.

Metallurgical test work continues by Resource Development Incorporated of Denver to enhance previously established recoveries for gold and copper.

Gold equivalent values for contained metal were calculated using $US 1,250/ oz Au and $3.00 /lb Cu.
