Search is further pleased to announce that patent applications have been filed in several countries for nickel laterite processing using the SALT Process. Separate applications have been lodged with the national patent offices in Brazil, Cuba, the Philippines, Australia, Europe (including the French overseas territory of New Caledonia), Indonesia, Colombia and the Organization of African States (including the Ivory Coast, the Republic of Cameroon and the Republic of Guinea). The national patent applications will be examined by the respective national patent offices in each of these countries. The national patents will be granted once the national patent applications comply with the requirements of the relevant patent office.
Search has now received a positive report from Votorantim Metais (Brazil) with respect to pilot plant testing of Caron plant waste materials from Niquelandia (Brazil). The report is under review and consideration by Votorantim and Search. Pilot plant testing of the Cipo nickel laterite project (Votorantim Novos Negócios Ltda) has also been successfully concluded. Evaluation of the technical results and the associated cost and engineering studies is ongoing. Bench scale evaluation of a suite of nickel laterite samples from the Pomalaa deposit of PT ANTAM (Persero) Tbk has been conducted via a service agreement at the University of British Columbia Hydrometallurgy Laboratory under the supervision of Dr. David Dreisinger . The results of the testing have been forwarded to PT ANTAM for review and comment.
