Inactive and Abandoned Mines (IAML)
<DIV STYLE="text-align:Left;font-size:12pt"><P><SPAN>IAML Points</SPAN></P><P><SPAN>Over 3,800 mineral properties have been located in the state during the last 150 years (Huntting, 1956). Many are undeveloped prospects of little economic importance. Sites that meet one of the following criteria are included: (a) more than 2000 feet of underground development, (b) more than 10,000 tons of production, (c) location of a known mill site or smelter. This subset of sites includes only metal mines no longer in operation. The term inactive, in addition to the term abandoned is used because it more precisely describes the land-use situation regarding mining and avoids any political or legal implications of surrendering an interest to a property that may re-open with changes in economics, technology, or commodity importance. This point data layer provides information about each site as a whole. Some sites (the Eureka Gulch area, the Monte Cristo district, the Pend Oreille west side workings, and the Roy and Barnum McDonnell mines) are lumped into single records. The names by which the mines at each of these sites are commonly known are included as separate records.</SPAN></P><P><SPAN>IAML Features</SPAN></P><P><SPAN>IAML features include (a) mine developments (adits, shafts, stopes, pits, etc.); (b) details on waste rock and tailings dumps; (c) mine drainage and impounded water; and (d) brief details on mine related structures.</SPAN></P></DIV>
