Mar-West Resources (MSR-V) is drawing favorable comparisons between two of its Latin American gold properties: the San Martin deposit in central Honduras and the Cerro Blanco prospect in southeastern Guatemala.
Like San Martin, Cerro Blanco is a hot-springs gold occurrence. Work to date has focused on a 3,000-by-500-metre area of siliceous sinter, with a coinciding gold-in-soil anomaly that extends over 2,000 metres by 350 metres. A 40-km induced-polarization survey was completed in January.
Geochemical and geophysical studies indicate that the most promising targets are two vertical diatreme breccia pipes, at the southern end of the sinter.
The breccia bodies occur 500 metres apart, along a north-south-trending structure. The area in-between is intensely silicified and represents a blanket-like target.
Surface chip sampling over one of the breccia pipes averages 1.4 grams gold per tonne for 20 samples taken in an area measuring 100 metres by 70 metres.
The zone is open in three directions, and Mar-West is following up its latest results with additional chip sampling and mapping.
The body of sinter associated with the pipes, and the related alteration, is mapped on surface and interpreted from geophysics to extend 1,100 metres north-south by 400 metres east-west. Based on geophysics, the vertical dimensions of the body appear to be funnel-shaped and narrow at depth. At a 75-metre depth, the siliceous alteration is projected to average 300 metres in width.
In the coming weeks, the company intends to drill at least 1,000 metres in 10 holes.
