Gold recovery costs Extracting gold from ore can be complicated and countless mines have failed because they did not recover enough gold to balance input costs The most commonly used process to extract gold is cyanide leaching based on a chemical reaction first identified in 1894 by L Elsner In addition to disclosing results determined in accordance with GAAP EDV may also disclose certain non-GAAP and pro forma non-GAAP results of operations including certain ratios operational and miscellaneous data as well as net income diluted earnings per share operating expenses and operating income that make certain adjustments or exclude certain charges and gains that are outlined in
