Assessment of Historical Leach Pads - Background, Objectives and Highlights
Historical mining of the American Girl, Padre y Madre, Queen and Oro Cruz oxide gold deposits by the American Girl Mining Joint Venture ("AGMJV";
Southern Empire believes that the gold-bearing material in the two historical leach pads may contain significant residual gold and, as a first phase of assessment, twenty-six (26) samples were collected; 12 from the historical Padre y Madre and 14 from the American Girl leach pads. Gold assay results are presented in Table 1 and sample locations are presented in Figures 1 and 2.

Southern Empire's President and CEO,
Steps Forward on the Historical Heap Leach Pads at the
To establish a NI 43-101 resource for the historical heap leach pads, Southern Empire has:
- Initiated permitting for sonic drilling of both the Padre y Madre and American Girl heap leach pads with both the
U.S. Bureau of Land Management ("BLM") andImperial County ,
- Initiated a review of historical AGMJV metallurgy in order to determine the best methods for gold extraction from the existing heap leach pad material, and
- Engaged Mr.
Garth Kirkham , the principal ofKirkham Geosystems Ltd. , ofVancouver, Canada , to oversee the resource establishment procedures at Oro Cruz. Kirkham Geosystems is a full-service provider of geoscience consulting services to the mining, environmental, oil & gas and geotechnical industries focusing on offering 3D computer modeling expertise using a variety of leading volumetric modeling systems.Mr. Kirkham is the Past-President of theCanadian Institute of Mining , Metallurgy and Petroleum (CIM) and is the co-Chair of theCIM Mineral Resources and Mineral Reserves Committee and the Chair of the Geoscientists Canada, Securities Committee. He is also currently a representative forCanada on CRIRSCO - Committee for Mineral Reserves International Reporting Standards.
Data Verification, Sampling Procedures and Quality Assurance/Quality Control (QA/QC)
Surface grab samples of rock chips from larger boulders combined with gravel and fines, all considered representative of the materials of the historical American Girl and Padre
Each sample was then in control of the geologist until it was shipped from
Samples were crushed, split and pulverized (250 grams to 75 microns ("u"); 200 mesh) using BVM process PRP70-250 or ALS processes CRU012 and PUL31, thena 30 gram homogenized sample was analyzed using fire assay techniques with an atomic absorption spectroscopy (AAS) finish (procedures FA430 at BVM and Au-AA23 at ALS). Four acid digestion of each sample was followed by multielement Inductively Coupled Plasma ("ICP") mass spectrometry analysis using MA3000 procedure at BVM and ME-ICP61 procedure at ALS. The results were reported in grams gold/tonne ("g Au/t"; also parts per million, or "ppm") and then converted to ounces gold per ton ("oz Au/ton"; also "opt") using a ratio of 34.28.
One pulp field standard and one trip blank were inserted with samples OCR-11 to OCR-27 that were analyzed at BVM. One pulp field standard and one trip blank was submitted with samples OCR-27 to OCR-49. which were analyzed at ALS. All lab standard and blank assay results reported in the BVM and ALS analytical certificates and all field standards and blank samples assayed within accepted QA/QC value ranges.
Standards and blanks submitted to BVM included the gold standard MEG-Au-09.03 and blank MEG-BLANK.10.14 purchased from
Standards and blanks including WCM Mineral Standard CU160 and WCM Mineral Standard CU172 were submitted to ALS Geochemistry with samples OCR-27 to OCR-49. These QA/QC standard material were purchased from WCM Minerals, a division of
