Exhibit C <br /> Mine Plan for the Pot o Gold Ranch Placer Mine <br /> Limited Disturbance Permit(110(2)) <br /> April 7, 2022 <br /> Mine Plan <br /> The Re-minin� of the Wilson Placer Resource <br /> Of what we know,the Wilson Placer appears to be a standard early 1900s dragline <br /> placer operation. They stripped the overburden of the cuts and stacked it on the top <br /> of virgin material such that potentially 1j3 of the original material could be intact <br /> under the strip piles. The tops of these piles have exhibited fine gold indicating that <br /> they may have stripped to within 2-3 feet of bedrock rather than testing.This was <br /> also common for this period of time. <br /> It is important to understand the processed areas as well as below the strip piles. A <br /> shallow pit within the washed channel will provide information on potential growth <br /> media that must be saved. Then the tailings will be tested to determine gold that <br /> was lost during processing which would be common if there was any amount of clay. <br /> The area below the tails will be explored for unmined ground that may have <br /> remaining resources. The strip piies will be evaluated.The tops will be tested to <br /> understand how much is economic#o run (Figure 1). That will lead to how much is <br /> just barren strip. Hopefully there is a topsoil zone under that which can be saved for <br /> reclamation. Under tha#will likely be a barren zone that can be stripped and placed <br /> over the original tailings. Under that will be virgin pay gravels that can be washed <br /> and placed over the old tailings. This will create an empty ditch for processing the <br /> next block. Any growth media (soil)encountered will be placed temporarily on the <br /> upper limits of the mine block until the concurrent reclamation can be started. <br /> To prepare a block for mining a pit/pond will be prepared to capture ground water <br /> for processing (Figure 2). The pond area will be (as marked), in an "L" shape about 40 <br /> feet wide and 300 feet long and 8 ft deep. tt will hold 718,176 gallons of water (.27 <br /> acres). The wash plant witl pump about 576 gallons per minute and return the same <br /> amount to the pond minus evaporation which wifl be about 300 gallons per month <br /> depending on conditions. Besides the volume of the water,the pond will act as a <br /> settling basin for fine silts and clays in the system initially. However, as the wash <br /> plant moves away from the pond the washed gravels will act as a filter capturing the <br />
