Abstract The report describes the field tests conducted at the Santa Cruz Joint Venture Site in Casa Grande, Arizona. These tests were carried out in existing core holes SC-46 and SC-19 and include: coring, water injection permeability measurements; geophysical wireline logging measurements of initial water saturation, porosity, and flow profile; and laboratory core leaching. The purpose of these tests is to provide supporting data for the commercial scale operation and experiment designs. Preliminary laboratory core leaching data indicate that a 50 gpl sulfuric acid strength that 10 gpl copper loadings are achieved at a net acid consumption of less than 3 1/2 lb acid per lb copper. These data are within the range of input parameters used to calculate the economics for the best mining scenario for the commercial design.
