KORE Mining Completes Second Phase of Engineering and Market Assessment of Imperial Salton Sea Materials

May 5, 2022

ACES Excess Waste Materials Have Competitive Advantage in Salton Sea Remediation

Vancouver, BC, May 5, 2022 – KORE Mining Ltd. (TSXV: KORE | OTCQX: KOREF) (“KORE” or the “Company”) is pleased to announce the results from a second phase of engineering and market assessment work for excess material from the Company’s 100% owned Imperial Oxide Gold Deposit (“Imperial” or “Project”), located in California, USA.  The excess materials are being studied to supply to remediation projects of the Salton Sea as part of KORE’s “A Clean Environment for the Salton Sea” or “ACES” initiative.  The work demonstrates that Imperial’s excess materials could potentially have an economic, social and environmental competitive advantage for supplying remediation projects in the southern Salton Sea.

ACES proposes to supply materials to remediate the Salton Sea, a major local health problem:

  • Saving lives of local stakeholders through reduced respiratory illness from dust pollution;
  • Preserving wetlands to benefit migratory birds suffering from increased Salton Sea salinity;
  • Restoring local community waterfronts to enhance quality of life; and
  • Rehabilitating playas to restore hundreds of thousands of acres of desert habitat.

KORE announced growing stakeholder support for ACES in the news release dated April 5, 2022.

KORE’s CEO Scott Trebilcock stated: “Cleaning up the environmental catastrophe that is the Salton Sea, will take tens of millions of tons of clean construction materials.  KORE’s ACES initiative – A Clean Environment for the Salton Sea – aims to supply clean, low environmental impact materials to these critical cleanup projects.  KORE’s recent work demonstrates that the Imperial material has a competitive advantage, most notably from a social and environmental perspective.  All other material sources would leave a massive scar in the landscape – not at Imperial, where the gold mine effectively pays for site backfill and remediation.”


In March of 2021 KORE commissioned a speciality consulting firm, Crystal Waters Consulting, LLC to conduct a market study for sale of excess mine material from the Imperial project.  The Imperial project has the advantage of having clean, river deposited sand and gravel conglomerate overlying the gold deposit.  This material has the potential to serve as a variety of construction materials.  The study demonstrated that there was a small local market for the materials, but the largest need was for Salton Sea remediation projects.  A follow-on study to dive deeper into the market for Salton Sea construction materials and to assess the capital and operating costs for processing and transporting Imperial excess materials was commissioned by the same firm in November of 2021.

The result of the study demonstrated that the Imperial excess overburden or ACES materials could potentially be competitive socially, economically and environmentally.  Land-use in Imperial and Riverside Counties are highly restricted with farms, nature preserves, military reserves and infrastructure greatly reducing the possible locations to source large quantities of suitable construction materials.  Further layering of geology, shows that many of the open areas do not have the right types of materials suitable for the reclamation projects at the Salton Sea.  The result is that Imperial’s ACES material is one of the few potential sources of large quantities of appropriate cover and construction materials such as rip-rap, integral to berms specified in many Salton Sea remediation projects.  The strongest competitive advantage would be for projects in the southern Salton Sea, where a majority of the toxic playas are forecasted.

It is further anticipated that ACES materials have the added social benefit of bringing taxes and jobs from the associated gold mine.  The gold mine pays for 100% backfilling and returning the site to its original topography and vegetation, in effect leaving zero long term visual impact on the land.  The three competitive advantages that have been identified by the Company make Imperial’s ACES initiative a leading candidate to save lives through Salton See remediation projects.


KORE owns 100% of the Mesquite-Imperial-Picacho 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.

Imperial has a mineral resource estimate and a positive preliminary economic assessment effective April 6, 2020 with the following highlights:

  • Robust economics: US$ 343 million NPV5% post-tax with 44% IRR at US$ 1,450 per ounce gold
  • Low capital intensity project with only US$ 143 million pre-production capital cost
  • Average 146,000 ounces gold per year over 8 years for 1.2 million ounces total production
  • Technically simple project: shallow open pit, run-of-mine heap leach with existing infrastructure
  • Value enhancement through Mesquite-Imperial-Picacho District exploration and resource expansion
