A Fairy Census

It's been awhile since I posted about our Little Friends. But then, I think they are hibernating in these parts. I have heard rumors (via the Kitties, so who knows how true those rumors are!) that they are planning a development in the Spring. 

Back to the subject at hand....

There has been a Fairy census taken (wonder if my Little Friends took part?). The results can be read here! Or for questions answered or more information, go to The Fairyist.

Or to read abut the results of the census and other musings, go to Malcom's Musings.

A great source of information about those Little People can be found at this blog,  Living Liminally . In fact the writer of that blog released a book last year and has another scheduled to come out this year. And currently she is writing about Fairy Taboos to enable us humans to better understand and live side by side with them.

Newmont Mining Corp.

Newmont Mining Corp. will be mining here until at least 2025. This year they are planning on extracting gold from the place where it all started - Poverty Gulch. Loosening and breaking the rock apart is a key component in mining. And that process means that explosives must be used.
Globe Hill is the name of the bare round mountaintop. Poverty Gulch,
where the new digging is going to be, runs at an angle to the bottom right hand corner. The building at the left is the Visitor's Center. The dust in the air is from an explosion.
The ore in Poverty Gulch is the highest grade and in the highest concentration compared to other areas of the mountain. It is also the closest to town. Many of the residents on the east side of Cripple Creek (and on the west side as well) are concerned that the blasting may affect their homes. But modern day blasting is a far cry from the sticks of dynamite used a century ago. Today's explosives are dropped into a small, deep hole and then the hole is filled with sand. If it's done correctly, a person can stand in relative close proximity to the blasting hole and never know the charge ever went off.  Us? Not too concerned. Our house has been here 118 years and has seen a lot in it's time. I'm sure some of the dynamite charges set off during the labor wars rattled a few windows.

Newmont and the Cripple Creek & Victor Gold Mine, like so many companies before them, contribute a lot to the local community. Generous grants are given to schools, museums, and the community center. The kids here have a fabulous basketball court, skateboard park, and playground.  A brand new adventure park complete with a bmx bike track, dog park, disc golf area and tons of state of the art playground equipment complete with a zipline! was just recently completed. Not too shabby for a small town.

This area has a tremendous amount of mining history. History which people travel from all over the world to come see. Newmont has recognized this fact and has done so much in trying to keep that history alive. A lot of the old mining buildings and ghost towns are on land owned by the mine. If mining operations threaten any of these structures, then they are moved and stabilized so people can enjoy them for many more years to come.

Reclaiming the barren landscape is the final life stage of an area which has been mined. When the pit was first begun, bristlecone pines dotted the top of the mountain. Seeds from their cones were collected so that they might be used to grow young trees to reforest the mountaintop. Newmont is also working with a State University to develop a method to grow aspen from roots. Aspen are notoriously hard to transplant.  Areas which have been seeded - much like the road department will seed the side of the roadway - are constantly monitored for health and stability. But I have faith in the methods used by Newmont. This company won an award for its reclamation of an open pit coal mine in Nevada.

Having the mine as a neighbor is not so bad. Our roads are in good repair and kept clear in stormy weather. Our town and other local institutions have many amenities that other small towns do not have. Of course, the casinos do play a small part in some of this. I will write about the casinos in the coming weeks.

Tours can be taken of the current mining operations. It's on the calendar for this summer.
***Yes. The aerial view of he mine does look like a SKULL!***

Cripple Creek & Victor Gold Mine

I love my Mother Earth. And I have always seen an open pit mine as an abomination. And yet, I have willingly moved next door to one.  (click on pictures to enlarge - the photos do not capture the immense size of the equipment being used or the pits being dug!)

The towns of Cripple Creek and Victor are marked.
Someone once said that until mankind quits devouring minerals like they were candy, mining and open pit mines will be necessary. A very true statement.

Gold was discovered in a gulch outside of Cripple Creek in 1890. Within five years the town had grown to 8,000 people. The neighboring town of Victor was founded in 1894 . By 1901, at the peak of production, there were 500 mines in the District and $77 million in gold had been taken from the ground. 

Gold production continued until it tapered off in the 1920's, with a brief resurgence in the 1930's. World War II saw a halt to all gold production. In 1995 , a new process of gold leaching was developed and extraction began again at the Cripple Creek & Victor Gold Mine. But this time the ore wasn't coming out of shafts, it was being mined in an open pit. 

I am not going to give a lot of details about the early days of gold mining here in the District. That is a story for another series of posts. What I am going to write about is the modern day mining which is currently taking place just over the hill. The current owner of the Cripple Creek & Victor Gold Mine is Newmont Mining Corporation, a world wide mining company.

Pit located on northeast section of mining area. This pit is now used for rock disposal.
An open pit mine is just what it sounds like. A great big hole in the ground that keeps getting bigger because of the rocks (minerals/ore) that are being taken out of the hole. Blasting (with explosives) is done which loosens the rock near or just below the surface of the ground. Large heavy equipment then takes out the loose rock to be processed. This process of blasting and hauling rock is repeated over and over until the ore is all extracted. Roads are built around the sides of the pit to allow the heavy trucks to drive down to the bottom.

This hillside is being stripped down to bare ground and will soon look like the photo below.

The gold found here is not in the form of a nugget or dust. It is found mixed in with other minerals and must be separated from these other components via a leaching process. The ore bearing rock is sent to a crusher then on to a mill for processing. Once the rocks have been milled down to a more manageable size,  they are then taken to a leach pit where the precious minerals are extracted. A diluted Potassium Cyanide solution is sprayed on the crushed gold bearing ore in the leach pit. The cyanide trickles down through the rocks, binding with the gold and silver. At the bottom of the pit are carbon filters which trap the cyanide/gold mixture.

Once the gold and other precious minerals are trapped in the carbon, it is then sent to another processing station where the gold, silver and other minerals are separated from the carbon and smelted down into bell shaped forms called dores. These dores are then sent to a refinery in Switzerland so the gold, silver and other minerals can be separated.

The rock which has no mineral value is loaded back on to dump trucks and taken to a part of the pit which has already been mined. There the rock is dumped and the mountain begins to take shape once again.

Dump trucks can be seen bringing rocks to be dumped.

We frequently follow tankers carrying potassium cyanide up the mountain road to Cripple Creek. Never see the gold shipment leaving the mine though. Wonder who's riding shotgun on that stagecoach?

On Monday, I will write about the new exploration going on at the mine and its impact on the local community. I'll also write about the community involvement of Newmont and the most important part of the mining process - reclamation.
