A pole-dipole IP survey was completed over a 2 kilometre by 2.8 kilometre grid with northeast trending lines spaced every 400 metres. The survey succeeded, detecting a large chargeability anomaly measuring 1.2 kilometres by 1.3 kilometres. The anomaly displays high chargeability readings, peaking at greater than 40 mv/V. The surface projection of the anomaly coincides with the area already mapped as prospective Laramide aged volcanic units that have been subjected to pervasive quartz-sericite-clay-pyrite ± iron oxides (phyllic) alteration, characteristic of the outer shell of a mineralized porphyry system. This mapped leached cap obscures almost all of the underlying geology, except in a small erosional window where San Marco personnel were able to map an area of potassically altered rocks. Mineralization which includes early stage veining contains copper, molybdenum and gold. Potassic alteration is a common feature of the ore-bearing zones of economically mineralized porphyry systems.
The geophysical modelling shows a large area of high chargeability starting just below the current surface with the highest values starting 200 metres below surface and extending down to 400 metres (the limit of the survey). The highest chargeability readings surround a core area with slightly lower readings. San Marco’s geophysical consultants consider the 1068 target highly prospective and have recommended a four-hole drill program as an initial test.
Robert Willis, San Marco’s CEO stated; “The IP survey has generated a classic “textbook” porphyry-style geophysical target. These geophysical results add additional support to our theory of significant vertical extent below the large surface footprint. Drill hole collars are expected to be located at or near copper/gold/moly mineralization, which has been locally, identified right at surface. Each new layer of data that has been generated at 1068 has simply strengthened the target potential.”
An initial 4 drill holes have been recommended to target across the gradient of higher chargeability associated with phyllically altered pyritic shell into the lower signature associated with the potasically altered and mineralized rocks.

National Instrument 43-101 Disclosure
This news release has been approved by San Marco’s CEO, Robert D. Willis, P. Eng. a “Qualified Person” as defined in National Instrument 43-101, Standards of Disclosure for Mineral Projects of the Canadian Securities Administrators. He has verified the data disclosed, including sampling, analytical and test data, underlying such technical information by reviewing the assay reports provided to San Marco by its independent testing laboratory.
The Company has implemented quality assurance (“QA”) and quality control (“QC”) programs to ensure sampling and analysis of all exploration work is conducted in accordance with the best possible practices. All sampling programs are carried out in a careful and diligent manner using scientifically established sampling practices designed and tested to ensure that the results are representative and reliable. Quality control programs appropriate to the type of sample and the mineralization are implemented, including such measures as external blanks, standards and duplicate samples. The security of samples from sample acquisition to analysis is a vital component of the sampling process. Procedures include the use of secure core logging, sampling, storage and preparation facilities as appropriate and the prompt, secure and direct shipping of samples to the laboratories. Appropriate sample security procedures are employed given the geographic and topographic conditions and the logistics created by the site location.
