Regulus Resources Inc. announced that it has delivered samples to Nuton LLC to begin the phase two metallurgical program utilizing Nuton's proprietary primary sulphide leaching technologies. The phase one metallurgical program determined that mineralization from AntaKori was amenable to Nuton's sulphide leaching technologies, while the phase two program is designed to expand on the results from phase one and refine the understanding regarding metallurgical recoveries for various styles of mineralization. Sample Selection, Preparation, and Methodology.

Samples were selected and composited from each of the main mineralization styles at the AntaKori project: high sulphidation, skarn and porphyry. A total of eight composite samples were taken totaling 1,448.7 kg. All samples were taken from Regulus drill hole core stored in the Company's Cajamarca warehouse.

The samples were shipped to SGS laboratories in Lima Peru for further sample preparation according to Nuton specifications and protocols, under the supervision of Transmin Metallurgical Consultants S.A.C. Once the samples have been prepared in SGS Lima, a small representative sample split will be sent to Nuton for detailed chemical and mineralogical analyses of each of the composite samples before commencement of the main phase two column test work. Chemical and mineralogical data will be used to predict column test results. The remaining prepared samples will be shipped from SGS Lima to Nuton's test facilities for phase two test work, which will entail samples being placed in columns with a height of 1 m, each under different controlled Nuton operating conditions.

The columns will be continuously monitored and it is expected that once samples are placed into columns, the full results will be available approximately one year later.
