Testing the strike extension of the orebody at the Mercedes mine in Ecuador, Northfield Minerals (TSE) has intersected 37 metres of copper-gold mineralization.
Northfield and its Ecuadorean joint-venture partner Minera Gribipe are testing a structural zone that extends from the Mercedes mine (which produced between 1940 and 1947) and a surface prospect called Esperanza, 1.5 km to the north.
The first hole tested the structure 75 metres north of the known mineralization at Mercedes and encountered an average grade of 0.8% copper and 3 grams gold per tonne. A high-grade interval contained in this intersection graded 1.7% copper and 10.2 grams gold.
The 37-metre mineralization is in stringer form, with pyrite, chalcopyrite, sphalerite and galena, and occurs in strongly altered andesites. The hole bottomed in mineralization at a vertical depth of about 80 metres.
A second, more steeply inclined hole drilled from the same location encountered similar stringer zones.
Northfield is also trenching and sampling three other targets on the same property.
