Steamboat Springs, CO — (September 28, 2022) – WESTERN SIERRA RESOURCE CORPORATION (OTC: WSRC) announces that its wholly owned subsidiary, Mitigation Solutions, LLC (MSL) signed, on September 17, 2022, an Agreement with the Santa Maria Valley Water Conservation District (SMVWCD) in Santa Barbara County, CA for the mitigation of Twitchell Dam and Reservoir. The Agreement has a value of $1.976 Billion payable over the 7-to-10-year term of the project—an estimated $200 million in average annual gross revenue. This scheduled revenue enhances the Company’s ability to fund its other natural resource projects without debt or dilution.

MSL will secure funding for SMVWCD from Infrastructure Investment and Jobs Act, The Inflation Reduction Act and the 2022 Omnibus Appropriations Bill through various Federal and State agencies, primarily the Federal Emergency Management Agency (FEMA), United States department of Agriculture (USDA), and the U.S. Department of Transportation (USDEOT). Additional financial participation by other Federal Agencies is anticipated. MSL has secured a $150 million Line of Credit for phased mobilization; and $40 million in Equipment Financing immediately available through institutional providers. The beneficiary of this Federally funded project is SMVWCD for purposes of stabilizing the Twitchell Dam and restoration of the ~224,300-acre-foot (~73.07 billion gallon) Twitchell Reservoir. MSL will remove and repurpose approximately 40 to 60 million cubic yards of ash-contaminated and non-contaminated sediments from the Reservoir basin. This sediment has collected in the Reservoir over the last four decades and has vastly reduced the Reservoir ability to recharge the local groundwater and aquafer that local agriculture and food production depends on. Returning the Reservoir to its original holding capacity also allows the Twitchell Dam and Reservoir to improve its capability as an essential flood control structure and source of water to fight wildfires.

Along with Dam stabilization and removal of sediment from the Reservoir basin, the scope of the project encompasses mitigation of influent-contaminated sediments, water contamination, and preemptively addresses the deposit of eroding soils from upstream drainages to mitigate future adverse effects for the Reservoir and damage to the Dam that sustains it. Global Clean Water, Inc. (GCW) has contracted with both WSRC and MSL to address functions in each of the four (or more) phases of the Twitchell project which is expected to require 7-10 years to complete.

The Twitchell Dam and Reservoir site is the first of several California locations where these contract services may be performed by MSL. Two additional projects are currently in queue.

MSL’s Principals have joined WSRC’s management team and bring with them a combined 200 years of disaster response/relief, mitigation, and restoration experience to the Company. This experience specifically includes, but is not limited to, natural disaster damage assessment, response, and recovery activities; flood-contaminated waterway restoration; mitigation of factors compromising lake, reservoir, and municipal water storage facility integrity; and failed water delivery system reconstruction. Global Clean Water, Inc., with its specialized protocols for mitigating contamination in potable water supplies, will be integral to these and other project requirements.

Photographic records, video, and written documentation will be made available throughout the term of the Twitchell project (and as specific on-site objectives are attained) for the benefit of the Santa Maria Valley Water Conservation District, its residents, and the Company’s shareholders.
