The Pacific Vein at Pinos Altos: A Lode of Promise and Peril

By the early 1880s, the mining landscape of southwestern New Mexico had begun to attract serious corporate investment, as railroad access improved and the Apache threat receded. ^[8] In this climate, the Silver City Mining and Milling Company secured three large ore bodies, including claims in the Pinos Altos area, as the basis for their operations. ^[8] A December 1881 report by mining engineer George E. Sill, prepared for the company, described a remarkable concentration of development on the "Volcano" and "Old Timer" claims, which together contained three distinct, parallel veins cropping out boldly for 1,500 feet. ^[6] Sill noted thirty-nine shafts and cross-cuts on the ground, every pound of removed matter being ore or mineralized matter, and he expressed confidence that the deposits would prove to be large, long-lasting ore bodies rather than narrow fissure veins. ^[5][7]

Bell, was producing 25 to 30 pounds of gold per week, and plans were underway to cast a 1,000-pound gold brick for exhibition at the 1893 Columbian Exposition in Chicago. ^[4][9] The mine’s output was considered sufficient that a half-ton brick could be produced in less than a year, and under favorable circumstances a full ton could be furnished. ^[4]

Around the same period, a miner named George Butler, employed at the Pacific mine in Pinos Altos, had a narrow escape when a mass of rock gave way and completely covered him while he was cutting a ditch. ^[10] He was extracted by fellow miners and taken to fresh air; though considerably bruised and cut, no bones were broken, and he was expected to return to duty in a few days. ^[10] The incident underscores the physical dangers that accompanied the district’s underground work.

In 1890, the Pacific mill closed down at 3 o’clock Thursday morning, having drained the reservoir of the Silver City Water Works of water. ^[1] This suggests the mill’s operations were directly tied to the municipal water supply, a relationship that could cause friction when mining demands exceeded available resources.
