The San Rafael Vein

Remnant resource of 762,000 ounces of gold & 10 million ounces of silver remaining in the old workings of the San Rafael vein*

Historic Production of 5 million ounces of gold equivalent

• Average grades: 10-12 g/t gold & 120-160 g/t silver
• Average Widths: 3 to 10 metres
• Bonanza grades: up to 50 g/t gold & 500 g/t silver
• Widths: up to 70 metres in places

Continuous vein mineralization over 2.4 kilometres of strike length

Mined from 1896 to 1929 by 3 companies concurrently in 3 contiguous sections:

• Mexico Mine (North)
• Esperanza Mine (Central)
• South Mine (South)

Mining closed down in 1929 due to:

• Labour difficulties
• Costs vs low price of gold
• Pumping technology

Flooding in one section of the San Rafael vein in 1929 resulted in the other two sections flooding and work ceasing abruptly and unexpectedly

The Full Potential of the San Rafael Vein has Never Been Properly Investigated.
