SMN Sun Summit Minerals Corp

San Marco Resources Inc. (TSX VENTURE: SMN), (The Company) has recently commenced exploration at its 100% owned 8500 ha La Buena property in Zacatecas State, Mexico. The southern boundary of La Buena is approximately 8 km north of Goldcorp's world class Penasquito mine and 3 km north of their Noche Buena resource area currently being explored. Other deposits in the area include the 3000 TPD underground Au/Ag/Zn/Pb Providencia mine 10km to the east and the Salaverna SX-EW open pit copper property 11 km to the southeast. La Buena is bordered on the northeast by concessions optioned to Goldcorp and currently being explored.

Chairman Robert Willis states "With new exploration data in hand, and seeing results of a few weeks of our own exploration, we intend to ramp up our efforts to further understand the geology, especially in the areas where magnetic and radiometric anomalies are coincident with surface precious and base metal occurrences. We expect that this work and additional detailed geophysics will help us zero in on potential drill targets."

While alluvium covers about 60% of La Buena, geology of exposed rocks include the same package of Cretaceous and Jurassic rocks that host the Providencia and Salaverna deposits. Caracol Formation (limey siltstone) is also widespread and hosts mineralization at Camino Rojo (50km to the south) and in part at Penasquito. Intermediate subvolcanics host mineralization at Goldcorp's Noche Buena resource area, and similar rocks also occur at La Buena.

The Company recently acquired from a major mining company, a helicopter flown geophysical survey completed in 1997, that included magnetic and radiometrics readings on 400m north-south line spacing. The data has been reinterpreted by an independent geophysicist and is now being used to in part, guide initial surface sampling and mapping. A cluster of strong magnetic anomalies occur around pyrite rich subvolcanic monzonite intrusive bodies which outcrop in the central portion of the property. (link, mag: to view, click here: http://www.sanmarcocorp.com/files/la_buena_mag.pdf) The intrusives have metamorphosed the surrounding Caracol siltstones to hornfels. Initial sampling in the area have returned gold values up to 5 grams per tonne from narrow structures and most importantly, up to 1.25 grams per tonne gold from the hornfels. Surface sampling has been expanded in this area as well as in the northern section of the property where scattered old workings occur. Previous sampling in this area reported gold values in the 0.5 to 3 gram range from structures and a "chimney" in Cupido Formation limestone.

Of significance, three long narrow magnetic anomalies occur under alluvium in the south central area of the property, and may represent subvolcanic dykes. Similar rock types are associated with mineralization at the nearby Noche Buena mine. In addition, again under alluvium, a cluster of magnetic anomalies occur along the La Buena southern property boundary and on trend with the Noche Buena stock.
