A diamond drill program by MacDonald Mines Exploration (MMP.A-A) has started testing the recently discovered Zona Campo Santos showing on the Golden Hill property in Cuba.
The prospect lies 1 km northwest of Big Golden Hill, where the company is carrying out a prefeasibility study on this and three other contiguous zones, which, together, host a near-surface oxide resource of 4.3 million tonnes averaging 1.1 grams gold per tonne.
The first of four planned holes at Zona Campo has been collared to test an induced-polarization anomaly. Measuring 300 metres long by 70 metres wide, the anomaly remains open along trend to the east and west.
To date, the company has tested the immediate area through surface work and ground geophysical surveying. Results from grab samples of oxidized outcrops yielded up to 1.4 grams gold and up to 100 grams silver, whereas three trenches exposed oxidized, quartz-rich veins hosted in altered porphyry. High concentrations of antimony, arsenic, mercury, bismuth, barium and lead are also reported from surface samples.
MacDonald owns a 25% interest in the Golden Hill property and is conducting the program on behalf of its two partners — GeoMinera, which has a 50% interst, and Golden Hill Mining (GHMC-C), which owns the remaining 25%. The former is owned by the Cuban goverment, whereas the latter is 42%-held by Mill City Gold Mining (MIY-V).
MacDonald is currently in negoitations with Mill City to acquire Golden Hill’s interest.
