At the southern portion of the tract, a tunnel has been driven in at right angles to the vein, which was thus reached at 100 feet, from whence it was carried northeast and southwest along the lode. The northeast branch has been driven 300 feet, exposing a vein of 40 feet with an unknown depth, the ores of which are soft and friable and easily mined.

It's the best time to make some plans for the future and it's time to
be happy. I have read this post and if I could I wish to suggest you few interesting things or suggestions.
Perhaps you can write next articles referring to this article.
I desire to read even more things about it! I couldn’t refrain from commenting.
Well written! Does your site have a contact page? I'm having trouble
locating it but, I'd like to send you an e-mail. I've got some ideas
for your blog you might be interested in hearing. Either way, great blog
and I look forward to seeing it expand over time.
