Previously Giesche’s Erben was a sole owner of Giesche Spolka Akcyjna. Silesian Holding Company was owned by Anaconda Copper Mining (65%) and the remainder originally by W. Averell Harriman, and then by Harriman or close affiliates and associates. SACO gave substantial loans to Giesche’s Erben, too. The funds for take-over and loan purposes were obtained by selling $15,000,000 collateral trust sinking fund bonds maturing August 1, 1941.
Schulte had close relations with a group of Swiss bankers. Just before war he established a subsidiary of Giesche’s Erben in Switzerland, called Non Ferrum (full name Non Ferrum Gesellschaft zur Finanzierung von Unternehmungen des Bergbaus und der Industrie der Nichteisenmetalle) and transferred Erben’s stock of SACO to that new company.
In 1941 the Swiss bank LaRoche, acting jointly with Schulte, established another company in Switzerland, Ikap (Internationale Kapitalanlegen Gesellschaft). Schulte convinced Harriman and Cornelius Kelley (president of Anaconda Copper) to sell their shares in Silesian Holding Company to Ikap. Unfortunately Swiss paper work held matters up beyond June 14, 1941, when the US Presidential freezing order was extended to Switzerland. This subjected the transactions to United States Treasury Department scrutiny and approval. As it was obvious that the stock was to be held for the benefit of enemy (a German corporation Bergwerksgesellschaft Georg von Giesche's Erben), the application to the Treasury Department for permission to make the necessary transfers was refused on July 26, 1941. Two later applications (of August and December) were also refused. Moreover, in November 1942, Alien Property Custodian, acting under Trading with the Enemy Act, vested German owned shares in Silesian-American Corporation.
Order No. 370: Silesian-American Corp. Executed November 17, 1942, signed by Leo Crowley, Alien Property Custodian: “Two blocks of stock - 98,000 shares of common and 50,000 shares of preferred stock in the Silesian-American, a Delaware corporation [are being confiscated]. The stock, prior to August 31, 1939, stood in the stock book of Silesian in the name of Non Ferrum, Zurich, Switzerland, a Swiss corporation, which held the stock for the benefit of Bergwerksgesellschaft Georg von Giesche's Erben, a German corporation”. This was the final nail in the “coffin” of great Eduard Schulte’s repatriation scheme.
