KORE MINING COMPLETES ADDITIONAL ENGINEERING AND ECONOMIC ASSESSMENT OF IMPERIAL PROJECT SCENARIOS

Project Economics Remain Strong Across All Project Scenarios

VANCOUVER, BC, April 19, 2022 /PRNewswire/ - KORE Mining Ltd. (TSXV: KORE) (OTCQX: KOREF) ("KORE" or the "Company") is pleased to announce positive results from additional engineering and economic assessment work for the Company's 100% owned Imperial Oxide Gold Deposit ("Imperial" or "Project"), located in California, USA.  The work assessed various scenarios in response to the position by the Bureau of Land Management ("BLM") of the possible need to move project infrastructure as announced August 20, 2021.  Economic modelling results for all scenarios were within the sensitivities of the April 6, 2020 positive Preliminary Economic Assessment ("PEA").  The work demonstrates that, regardless of the ultimate location of Imperial's processing infrastructure, Imperial has the potential to be a mid-tier gold mine with compelling project economics.   

• Base economics: US$ 343 million NPV_5% post-tax with 44% IRR at US$1,450 /oz gold
• Alternate scenarios could increase effective operating costs an estimated 5-15% from PEA
• US$ 263 to 317 million NPV_5% post-tax at US$1,450 / oz gold from PEA sensitivities
• Project remains highly economic in all scenarios evaluated
• Significant gold leverage: >US$ 600 million PEA NPV_5% at recent spot US$1,900 /oz gold
• Unchanged 146,000 ounces gold per year and over 1.2 million ounces total production
• Additional value enhancement through Mesquite-Imperial-Picacho District exploration and resource expansion remains untapped

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, and there is no certainty that the preliminary economic assessment will be realized. Mineral resources are not mineral reserves and do not have demonstrated economic viability.

KORE's CEO Scott Trebilcock stated: "The alternate infrastructure locations assessed in our recent work shows robust project economics across all scenarios in-range of our 2020 PEA economic sensitivities.  Imperial remains a technically simple, high-return gold project in a safe, politically stable jurisdiction with a long tradition of gold mining.  All scenarios use conventional open pit mining techniques, proven processing technology and existing infrastructure."

Mr. Trebilcock continued: "With our ACES initiative – A Clean Environment for the Salton Sea – the Imperial Project aims to deliver positive social and environmental impacts for local stakeholders – cleaner air from ACES, generational job creation and training, respect for land heritage and complete land restoration post-mining including backfilling open pits.  All KORE's development plans meet or exceed California's stringent reclamation and environmental laws while delivering meaningful positive local stakeholder impact."

Marc Leduc, KORE's COO since late 2019, has advised the Company he will be retiring in May of 2022.  Mr. Leduc is looking forward to spending more time with his wife and family.  The Board would like to thank Mr. Leduc for his service over the last several years.  A replacement, who is expected to focus on delivering exploration permits and drilling, is being actively recruited.

The PEA was prepared in accordance with National Instrument 43-101 ("NI 43-101") by Global Resource Engineering (Denver) ("GRE") and supported by Geo-Logic Associates.  The team was led by Marc Leduc, P.Eng., the COO of KORE Mining.  The results were announced April 6, 2020 and the technical report is available on KORE's website at www.koremining.com or on our SEDAR profile at www.sedar.com.

Life-of-mine ("LOM") calculation and "Mine Life" is defined as the duration of mining operations, is eight (8) years.  There are additional years of site work for residual leaching, washing, back-filling and reclamation modelled.

The following table demonstrates the post-tax sensitivities of NPV and IRR to operating cost changes.  Recent assessment of alternate mill sites following BLM challenge to the mill sites used in the PEA base case showed potential effective operating cost increases of 5-15% (bold):

At current gold spot price of ~$1,900 per ounce gold, NPV is US$610 million with a 70% IRR.  The following table presents the post-tax sensitivities of NPV and IRR to gold price per ounce:

In response to the BLM's position as set out in KORE's press release issued August 20, 2021, KORE re-engaged the 2020 PEA engineering team to assess the potential impact of moving Imperial infrastructure from locations south of the open pits assumed in the PEA to east of the open pits.  The alternate infrastructure locations, outside of the Indian Pass mineral entry withdrawal, would avoid the matters raised by the BLM.  The alternate infrastructure locations would only be used if the PEA base case south infrastructure options were not available in the future as KORE has the right to challenge the BLM views. 

The engineering work developed eight mine plans and supporting economic scenarios that looked at alternate infrastructure configurations and trade-offs including conveying and crushing scenarios.  Crushing and conveying were further investigated to offset the longer haul distances to the alternate infrastructure locations.  The work was conducted to the same standard as the previous PEA work.

The results were all positive economically with ranges from an equivalent of 5-15% increases in operating cost from the PEA mine plan economic sensitivities at $1,450/oz gold.  At higher gold prices, the crushing and conveying cases become more attractive due to higher recoveries post-crushing.  Whichever infrastructure locations are ultimately used to permit the Imperial Project, the work shows potential for a robust mid-tier gold mine with compelling project economics. 

KORE considers the results of these studies as demonstrating the flexibility of the mine plan to changes to location of infrastructure within the cost sensitivities of the PEA study, and not a material change to the results of the PEA study.

KORE owns 100% of the Mesquite-Imperial-Picacho District ("District") which consists approximately 31,000 acres of claims capturing the entire 28-kilometer trend from the operating Mesquite mine (Equinox Gold – TSX:EQX) to the closed Picacho mine and including KORE's Imperial project.  In the District, gold is hosted in local fault structures related to a series of regional faults connecting the known District deposits.  Those three District deposits (Mesquite, Imperial and Picacho) were discovered in exposed outcrops and from placer workings.  The rest of the District is covered by alluvium and has never been systematically explored. 

The Mesquite-Imperial-Picacho District centers on KORE's Imperial project.  Imperial is a structurally controlled intermediate sulfidation epithermal gold deposit.  The 100% oxide gold deposit is currently defined at 2.44 kilometer long and up to 0.75 kilometer wide and is open both along strike and downdip.  It is hosted in a shallowly southwest dipping, amphibolite grade metamorphic rock suite along a west-northwest trending low-angle regional thrust fault system which controls the regional geometry of mineralization.  East-west striking, post-mineralization normal faults control the property scale geometry of mineralization.  Geophysical characterization of the deposit and regional controlling structures is an essential component of exploration for additional resources.

The Company's mineral resource estimate is prepared in accordance with NI 43-101 and the preliminary economic assessment is summarized in the report titled "Preliminary Economic Assessment – Technical Report Imperial Gold Project" effective as of April 6, 2020 and revised and amended on June 10, 2021, prepared by Terre Lane and Todd Harvey of Global Resource Engineering and Glen Cole of SRK Consulting (Canada) Inc.

KORE Mining is focused on responsibly creating value from its portfolio of gold assets in California, USA. The Company is advancing the Imperial project towards development while continuing to explore across both district-scale gold assets.  Management and Board, along with strategic investor, Eric Sprott (26% owner), are aligned with all KORE shareholders with the goal of creating per share value.
