San Marco Continues Exploration at Cuatro de Mayo; Samples 1.2 m of 26.4 g/t Gold on Newly Discovered Vein at Chunibas and Discovers New Gold Target at Corral

By September 14, 2015December 11th, 2019No Comments

Vancouver, B.C. – September 14, 2015: San Marco Resources Inc. (SMN: TSX-V) (“San Marco” or “the Company”) releases assay results from continuing exploration at its 100% owned and optioned Cuatro de Mayo Project in Sonora, Mexico.

Sampling and mapping at the El Chunibas target resulted in identification of new high grade veins, presence of mineralization in the wall rock and expansion of the veins along their strike.

Rock sampling of the newly discovered Corral target confirmed the presence of gold mineralization.

El Chunibas Target

Rock chip sampling completed in the northern extension of Santa Rosa vein system identified a new gold bearing vein that returned 1.2 m @ 26.4 g/t Au.

Wall rock mineralization previously identified around the Santa Fe vein that returned 10 m @ 3.8 g/t Au in the hanging wall (see San Marco news release of May 06, 2015) was also confirmed around the Western vein. Additional sampling of the Western vein confirmed the presence of previously reported high grade gold mineralization (8.42 g/t Au), and also identified the presence of mineralization in the wall rock (6 m @ 0.1 g/t Au and 9 m @ 0.2 g/t Au).

Variability of gold assay results obtained from re-sampling of the same interval (Santa Fe and Gusima veins) and re-assaying of sample rejects (Santa Fe vein) confirmed the presence of free gold (also seen during current activities by local miners).

Newly identified mineralization in the vein wall rock could be a significant occurrence for any future mineral resource generation.

Strike length of the known veins, the Santa Rosa, Santa Fe, Gusima and Western, was extended from 400 m to 1 km as a result of additional soil sampling and mapping. All four veins known to date are open to the south, with the Gusima and Western veins open to the north as well (see PDF presentation on Company website:

Additionally, recent exploration identified two sub-parallel veins located on both sides of the Western vein.

The Chunibas targets are a series of veins hosted in intrusive rocks that have intruded tuff agglomerates. To date, several sub-vertical veins and numerous high-grade iron-oxide shear zones have been identified on the property.

Presently, the mineralized zone with gold bearing veins, shears, and mineralized wall rocks, occur over an area that is approximately 750 m wide and 1.5 km long, and is open in all directions.

Corral Target

Reconnaissance rock sampling of this newly discovered vein system confirmed the presence of gold mineralization, 0.6 g/t Au collected as a composite over 10 m.

The Corral target is a newly discovered low sulphidation system with strong veining exhibiting massive, bladed, comb, cockade, and crustiform quartz textures. The Corral vein system is at least 1.3 km long, and over 400 m wide with individual quartz veins that can reach up to 1 to 2 m in width.

The Corral vein system is open in all directions (see San Marco news release May 27, 2015), is very similar to the Oregano vein system and is located approximately 1 km to the east from Oregano (see San Marco news release of May 6, 2015).

National Instrument 43-101 Disclosure

The technical information contained in this document has been verified, and 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.

Samples were prepared for assay at Bureau Veritas Minerals (Acme/Inspectorate) Lab in Mexico and assayed at their facility in Vancouver, BC. Assaying protocols are as follows: A 15 gram split is analyzed for 36 elements using ICP-ES/MS method (AQ201). Sample results greater than 1000 ppm Cu, Pb, Zn, Mo, Ag over 10 ppm, and Sb, As, Hg over the detection limit are re-assayed, using hot multi-acid digestion using ICP-ES method (MA370). Samples that report Au >100 ppb in AQ201 are analyzed by fire assay, AA finish (FA430) using a 30 g sample. Over-limit Au from FA430 and/or Ag from 370 is automatically assayed (30 g) via fire assay fusion and gravimetric finish (FA530).
San Marco’s sample collection, integrity, and quality control and assurance procedures are in line with industry best practices and include the following. Field work is verified by a Qualified Person. Data is accurately recorded in the field and all data points are located with respect to known reference points. The exploration process (including planning, mapping, sampling, sample preparation, sample security and analysis or testing) is carefully documented and accompanied by a detailed record setting out the procedures followed and the results obtained.

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.

Forward Looking Information

Information set forth in this document may include forward-looking statements, such as: the nature of additional work that may be undertaken on the Cuatro de Mayo project; the potential size of the mineralized targets identified to date; and the potential mineral deposit type of the Cuatro de Mayo targets currently identified. While these statements reflect management’s current plans, projections and intents, by their nature, forward-looking statements are subject to numerous risks and uncertainties, some of which are beyond the control of San Marco Resources Inc. Readers are cautioned that the assumptions used in the preparation of such information, although considered reasonable at the time of preparation, may prove to be imprecise and, as such, undue reliance should not be placed on these forward-looking statements.
