In order to complete their trial of the capabilities of Sŏmbrĕrētĕ as a mining district, the Company has commenced a new shaft, called La Concordia, "denounced" by the brother of Don Narcisco Anitua, upon a part of the vein never before explored. This shaft is situated to the North-west of all the old workings, a little beyond an arroyo, or ravine, in which the crest of the vein is distinctly visible, and from its size appears to announce a lode of no common dimensions.
In December 1826, the workings were 112 varas in depth. At 120 varas, a first level was to be driven in the direction of the vein, which it will cut at the distance of thirty-seven varas, if the inclination be the same below, as in the shaft of La Cruz. The necessary buildings at Concordia were all complete, and excellent of their kind; and should fortune favour the enterprise, not a moment would be lost in turning the produce to account. It is regarded by professional men as one of the most interesting experiments that has yet been tried in Mexico, and, whatever be the result, it deserves to be repaid with success.
A similar attempt to explore an untried portion of the Veta Negra has been made, by sinking the new shaft of San Lucas, in which the vein had been cut a short time before my visit to Sŏmbrĕrētĕ; the
