FINAL LONG VALLEY PROJECT PEA HIGHLIGHTS:
-
US
$273 million
NPV
5%
post-tax with IRR of 48% at
US$ 1,600
per ounce gold -
Significant leverage to gold:
US$ 395 million
NPV
5%
at recent spot
US$ 1,900
per ounce gold -
102,000 ounces gold per year over 7 years at AISC* of
US$ 773
per ounce - Technically simple: shallow open pit, heap leach with nearby infrastructure
- Unmodelled silver potential from metallurgical test-work
- Shallow oxide and sulphide feeder exploration potential to further enhance project
OPPORTUNITIES:
The PEA outlined a number of initiatives that may enhance the Project including:
- Assaying silver in all future drill programs to add silver into the resources;
- Conducting metallurgical tests to establish optimal crush size and cement addition;
- Performing test work on very low-grade samples to determine viability of run-of-mine leaching;
- Reviewing contract mining to reduce initial capital; and
- Drilling for more oxide resources and deep sulfides to look for high-grade feeder zones.
KORE’s CEO
Scott Trebilcock
stated: “KORE has the unique advantage of having two simple, low-cost heap leach projects in one Company. At
$1,900
per ounce gold, the after-tax NPV
5%
for Long Valley and Imperial is
US$ 395 million
and
US$ 660 million
respectively or at current exchange rates,
$530 million
and
$ 880 million
Canadian dollars. That is a lot of potential value to deliver to KORE shareholders through development that we believe is to be unlocked as we continue to advance the exploration and development of these assets.”
Mr. Trebilcock continued, “In addition to development, KORE has an array of exploration opportunities to grow ounces-in-the ground and make new discoveries. KORE is currently permitting drill programs at both Long Valley and Imperial while completing our recently extended drilling campaign at our FG Gold project in
British Columbia
.”
Refer to the Long Valley PEA Summary infographic in
Figure 1
.
The Long Valley PEA demonstrates strong economic returns while being in full compliance with
California’s
stringent operating and reclamation standards. Long Valley has clear upside potential from drill targets on-strike and lateral to the current modelled oxide mineralization and KORE intends to aggressively explore this untapped potential.
The full 43-101 PEA technical report is available on our website at
koremining.com
and has been filed on SEDAR under the Company’s issuer profile at www.sedar.c
om
.
The PEA is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the PEA will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
PEA SUMMARY
The PEA was prepared in accordance with National Instrument 43-101 (”
NI 43-101

Several minor revisions to estimates from the original
September 15, 2020
new release were made including but not limited to recovery kinetics, operating costs, corporate taxes and property taxes. The net effect of the revisions was an increase of
US$ 10 million
in after-tax NPV
5%
.

NEXT STEPS
This PEA demonstrates the robust nature of the current Long Valley mineralization. However, there is a clear opportunity to grow shallow oxide mineralization as the mineralization remains open in all directions and on a separate parallel structure. Additional mineralization could extend mine life, reduce capital intensity and generate higher project economic returns. A summary of oxide expansion targets is included in
Figure 2
.
Additionally, as a fully intact epithermal deposit with a large at surface footprint, Long Valley has the potential for high-grade sulphides in the underlying feeder structures. Discovering high-grade sulphides would open up additional development pathways for the Project, such as underground mining and milling of mineralization. A summary of sulphide expansion targets is included in
Figure 3.
KORE plans to drill-test the highest priority oxide and sulphide targets. KORE is currently permitting drill pads with our regulator the US Forest Service (”
USFS
“). Drilling is planned for H1 2021, subject to USFS permitting timelines. Details of the Long Valley exploration targets are in KORE news releases dated
January 30, 2020
and
March 24, 2020
.
FINAL LONG VALLEY
PEA DETAILS
GRE notes that the Long Valley Project has an abundance of drill data as a result of the exploration completed in the 1980s and 1990s. The Project also has metallurgical sampling and testing from previous owners, reviewed by GRE, to support the initial engineering design. This data will act as an important background and aid in the design of future work on the project.
MINING & PROCESSING
The PEA presents an open-pit, heap leach scenario where oxide, transition and sulphide ore is stacked on the leach pads by conveyors after two stages of crushing and agglomeration. The conveyor system is also used at the end of the mine life to backfill the final pits and reclaim the site to
California’s
stringent standards. In the design process, the engineering team also looked at several other scenarios:
- Silver production; a Merrill- Crowe precious metal recovery circuit is included in the project design to recover both gold and silver. Silver is NOT quantified in the resource or PEA as it was not assayed regularly in historic drilling but was seen in all of the previous metallurgical test work.
- Smaller, oxide only mine plan that had lower stripping ratio, lower capital and operating costs but yielded less ounces. KORE ultimately selected the mine plan with the most ounces recovered as those ounces would likely be mined at current metal prices.

OPERATING COSTS
Mining costs for owner operated mining, processing and other costs were developed from a mix of first-principle engineering and benchmarked to the many ROM heap leach operations in
California
and nearby Nevada. The Long Valley Project is located near a large skilled labour pool and has local access to road and power infrastructure. The Project has several options for water locally with potential surface and ground water sources.

The assumed truck diesel fuel price in the PEA is
US$ 2.00
per US gallon. About 11% of the mining cost is fuel so lower fuel prices would decrease mining costs moderately.
INITIAL PRE-PRODUCTION AND SUSTAINING CAPITAL COSTS
Initial capital costs in the PEA are
US$ 161 million
including a 25% contingency. Infrastructure costs are low due to the proximity of road, water and power infrastructure. Initial capital also assumes KORE is the owner-operator of all equipment. Further enhancements may be possible with contract mining. Sustaining capital is mainly for heap leach pad expansion and additional mining equipment.

ALTERNATIVE PERFORMANCE MEASURES (NON-IFRS MEASURES)
Items marked with a * in this news release are alternative performance measures. Alternative performance measures are furnished to provide additional information. These non-IFRS performance measures are included in this news release because the Company believes these statistics are key performance measures that provide investors, analysts and other stakeholders with additional information to understand the costs associated with the Project. These performance measures do not have a standard meaning within IFRS and, therefore, amounts presented may not be comparable to similar data presented by other mining companies. These performance measures should not be considered in isolation as a substitute for measures of performance in accordance with IFRS.
“Cash Costs ” and “Cash Costs (LOM)” are a non-IFRS measure reported by KORE on an ounces of gold sold basis. Cash costs include mining, processing, refining, general and administration costs and royalties but excludes depreciation, reclamation, income taxes, capital and exploration costs for the life of the mine, defined above as 7 years.
“All-In-Sustaining-Costs” (“ASIC”) is a non-IFRS measure reported by KORE on a per ounce of gold sold basis that includes all cash costs noted above (mining, processing refining, general and administration and royalties), as well as sustaining capital and closure costs, but excludes depreciation, capital costs and income taxes.
ABOUT LONG VALLEY GOLD DEPOSIT
Long Valley is 100% owned epithermal gold project located in
Mono County California
. The Long Valley deposit is an intact epithermal gold deposit with a large 2.5 by 2 kilometer oxide gold footprint.
The Long Valley deposit is an intact low sulphidation epithermal gold/silver deposit, hosted within a melange of fine to coarse volcanogenic sedimentary lithologies. Mineralization at Long Valley has developed due to a combination of deep-rooted fault structures and a resurgence of rhyolite within an active caldera. The Hilton Creek Fault structure transects and served as a fluid conduit for interaction with the underlying hydrothermal system, while the rhyolite resurgence caused brittle fracturing of sediments and created voids or traps for mineralization and gold deposition. The combination of these factors yields strongly altered kaolin and quartz-hematite zones that are the primary host for gold mineralization.
The Hilton Creek Fault remains underexplored on-strike north and south and several parallel structures have been defined using geophysics, the eastern one hosting some of the current mineral resource and the western one being unexplored. Long Valley is therefore open to new oxide discoveries in all directions. More details on the deposit geology and exploration potential can be found in KORE’s
January 30, 2020
and
March 24, 2020
news releases.

www.sedar.com
.
Forward-looking statements contained herein are made as of the date of this news release and the Company disclaims any obligation to update any forward-looking statements, whether as a result of new information, future events or results, except as may be required by applicable securities laws. There can be no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements. Accordingly, readers should not place undue reliance on forward-looking information.
There is no certainty that all or any part of the mineral resource will be converted into mineral reserve. It is uncertain if further exploration will allow improving the classification of the Indicated or Inferred mineral resource. Mineral resources are not mineral reserves and do not have demonstrated economic viability.
Cautionary Note Regarding Mineral Resource Estimates:
Information regarding mineral resource estimates has been prepared in accordance with the requirements of Canadian securities laws, which differ from the requirements of United States Securities and Exchange Commission (“SEC”) Industry Guide 7. In
October 2018
, the SEC approved final rules requiring comprehensive and detailed disclosure requirements for issuers with material mining operations. The provisions in Industry Guide 7 and Item 102 of Regulation S-K, have been replaced with a new subpart 1300 of Regulation S-K under the United States Securities Act and will become mandatory for SEC registrants after
January 1, 2021
. The changes adopted are intended to align the SEC’s disclosure requirements more closely with global standards as embodied by the Committee for Mineral Reserves International Reporting Standards (CRIRSCO), including
Canada’s
NI 43-101 and CIM Definition Standards. Under the new SEC rules, SEC registrants will be permitted to disclose “mineral resources” even though they reflect a lower level of certainty than mineral reserves. Additionally, under the New Rules, mineral resources must be classified as “measured”, “indicated”, or “inferred”, terms which are defined in and required to be disclosed by NI 43-101 for Canadian issuers and are not recognized under SEC Industry Guide 7. An “Inferred Mineral Resource” has a lower level of confidence than that applying to an “Indicated Mineral Resource” and must not be converted to a Mineral Reserve. It is reasonably expected that the majority of “Inferred Mineral Resources” could be upgraded to “Indicated Mineral Resources” with continued exploration. Accordingly, the mineral resource estimates and related information may not be comparable to similar information made public by
United States
companies subject to the reporting and disclosure requirements under the United States federal laws and the rules and regulations thereunder, including SEC Industry Guide 7.
