Page two <br />fact still remains that water is not existing from Bear's portals. Beaz Coal believes that the water <br />is exiting from the hillside from the old Edward's mine portals. The Edwazd's portals aze located <br />at the B seam outcrop elevation, and the Bear portals being in the upper C seam, approximately <br />fifty feet of separation between the two portals <br />Edwazd's Mine did have portals within the area that the water is immerging from the hillside. An <br />older photo that was taken during Bear's active construction at the mine site demonstrates the <br />evidence of the portals. The photo shows old concrete sWChues that were used by the Edwards <br />employees. (See photo #2). A major portion of the Edwazd's mining activities was in the B seam, <br />shown on a mine map that is furnished. (See map #1) <br />Upon review of the mine map provided, the map shows that the B and C seam have a slight dip <br />of 3 to 5% in a northeasterly direction. If water is present within the Bear's workings the water <br />should be coming out of the old fan portal which is the lowest of elevation, but the water is not <br />coming from the C seam portals but that of the lower B azeas. The entire mined area overlying the <br />previous mined Edwazd's workings, was dry up to the date of mine closure and was dry the day <br />the Bear's portals were sealed. <br />Upon review of the water records, within the affected area, has shown that the water in the <br />subsoil was present by the water samples that were taken from Well AAI, which was buried from <br />the landslide. Conductivity of the water in Well AAl, in 1987, shows a relativity low <br />conductivity number until 1989, when the conductivity greatly increased in value, varying in the <br />3000 mhos/cm range. When the water from AAI, is compared to the water in AA3, which is <br />located in a northeasterly direction from AAI, there is a draniatic difference in the conductivity <br />values, basically 300Nmhos/cm versus 3000Nmhos/cm values. <br />(See graph and values # 1 and #2) <br />Water samples that have been collected from the water exiting from the hillside show relative the <br />same conductivity values that were sampled from Well AA I. The conductivity of the water <br />coming from the hillside has held basically stable, some samples have increased in conductivity <br />and some samples have a lower value, but basically have held stable. The question has to be <br />raised if the water is coming from one single source further in the mountain or has it been stored <br />in old mine workings and finally has filtered a path to the surface. <br />Photo number three shows that the movement of the hillside is probably not related to any mining <br />activities but is probably the movement of the alluvial material that has been moving for several <br />years through normal erosion. Although, the alluvial material probably broke away from the main <br />structwe of the mountain at the B and C seam outcrop level thus, making the cliff looking <br />structure that remains today. When the slippage of the alluvial material at the outcrop level <br />occurred, the plug that held the water back was removed, allowing the flowage of water to the <br />surface at the constant rate that is seen today. There was probably some flowage in the shallow <br />subsoils that went unnoticed. <br />The old Edward's mine could have been, and still possibly full of water either from spring water <br />that has accumulated for past yeazs, or possibly from external filling from surrounding areas, and <br />
