Forty-Niner panning for gold |
Most of us know about the discovery of gold in California in
1849, which led to the California Gold Rush. But not as many know that gold and
silver discoveries happened in other places as well. One such discovery of both
gold and silver was in Virginia City, Nevada (or as it was know in those days,
Utah Territory) in 1859.
Within a handful of years after the California Gold Rush
started, it peaked and waned. Many who had staked everything to find their
fortunes in California’s gold fields lost everything instead. In order to get
back on better footing, they wandered farther afield, hoping to find a new vein
of ore. A few of the lucky ones did—in Virginia City, Nevada.
At first, the prospectors were focused on gold. However, as
they dug deeper into the ground, they found a layer of rich black sand, black
manganese mixed with a blue-gray quartz. Upon testing the strange sand, they
found it was three parts silver to one part gold. One of the original people to
lay claim to this strange sand was Henry T.P. Comstock. And so began silver
mining in America. The discovery became known as the Comstock Lode.

The silver was buried in the ground or in the mountainsides,
so it had to be dug out. Thankfully, the consistency was such that it could be
easily dug out with a shovel at first. But as these miners had to dig deeper
and deeper, several problems arose. Cave-ins were one such problem. The soil
was too soft, and many lost their lives as the surrounding ground gave way. To
combat that problem, a German mining engineer created a special timber support
system called Square Set Timbering to strengthen the mine shafts.
Another problem was that the mine would fill with water,
making it difficult and costly to continue the mining process. At first, large
pumps were employed to pump the water up to the shaft openings and out of the
mine. But this was very cost prohibitive and time consuming.
Adolph Sutro |
A Prussian-born engineer by the name of Adolph Sutro
proposed an answer to this issue. Build a horizontal tunnel through which the
water could flow out of the mine on its own. Said tunnel would also provide
other benefits, in that it would help to vent the poisonous gasses that often
built up in underground mines, and it would provide a lower-cost method to remove
the ore and transport miners in and out of the mine. Construction of the tunnel
began on October 19, 1869.
While the tunnel presented many positive reasons to proceed,
some of the mine bigwigs feared that Sutro would use the tunnel to his own
benefit in order to take control of the entire Comstock Lode. Sutro struggled
to find the monetary backing to proceed with the project until he was finally
able to secure a loan from a London bank.
During the construction phase, Sutro was known to work right
alongside those he hired as tunnel diggers. He faced the same avalanches,
mudslides, and poisonous gasses that his diggers faced, and he often was the
first one in and last one out of the tunnel they were constructing. The tunnel
was completed in 1878, nearly nine years after it began, and it cost a whopping
$5 million to complete. (To put that in some context, that would be
$119,047,619.05 in today’s dollars).
The Sutro Tunnel emptied nearly 4 million gallons of water a
day from the mine. Sutro rented use of

Because of his work on the tunnel, as well as his great
profit from it, Sutro became known as the King of the Comstock.

We can learn a good lesson from Mr. Sutro--get out while the getting is good. Smart man.
ReplyDeleteAmen, Vickie! He certainly knew when to part ways!
DeleteInteresting how silver found where the gold is! Thanks for the post. sm wileygreen1(at)yahoo(dot)com
ReplyDeleteGlad you stopped by, Sharon.
DeleteInteresting. I've always thought silver was a hard ore where you had to use a pick axe to get it out. This puts a different aspect to it. Thanks!
ReplyDeleteGlad I was able to share some new information with you, Anita!
DeleteWow, talk about leading by example - first in, last out. Nine years facing life and death adversities is a long time, not to mention cost, to follow a dream.
ReplyDeleteThank you for this story. Did you know there's a group of us working on restoring the site and the tunnel?
ReplyDeleteNo, I didn't know about this! That's fantastic. Thank you for letting me know.
