inferences.
Dimensions of the Lode. — The Cobre lode, as at present known, is
limited in its crop to a distance of about a mile, but it probably
ranges further to the east. Near the eastern extremity a branch is
given off, making an angle of about 30°, and proceeding south-west.
At the bifurcation, which is well seen on the steep banks of the
Cobre River, both lode and branch are nearly vertical, and the latter is
large ; but as it proceeds it becomes irregular, and is broken up and
intersected by numerous threads and strings. The main lode is cut
off to the west by a cross course, after being heaved by several slides
of small amount. See fig. 3.

(The arrows mark the dips.)
Although the whole extent of the lode, as known by the crop,
extends to 1800 yards or thereabouts, it is but a small part of this
that can be regarded as valuable. The whole workings on the prin-

cipal vein are limited to a linear extension of 800 yards, and the

This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:
Public domain

This work is in the public domain in its country of origin and other countries and areas where the copyright term is the author's life plus 70 years or fewer.


This work is in the public domain in the United States because it was published (or registered with the U.S. Copyright Office) before January 1, 1929.


This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.


Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
