Economic Mill

Last updated: 03.06.2006 18:27


Thanks to a very friendly & helpful seller at ebay I was able to at least get a glimpse of some of the info in the 1904 Annual report of the United Gold Mines Company, typical my luck I was unsuccessful of winning it as my US$350 was no match for those with way larger bank accounts then mine, but at least I got some help in getting to know what this reports holds as before this listing I had no idea at all. So, thank you so much!!
Should you the reader of this have access to this annual report, I would love to hear from you - I'm after the info in it, not the report it self per say, so please email me if you are willing to help!
The little info I have is listed at bottom here.


Thanks to a listing on ebay for some expansive gold stuff (bar/medallions) I found a short newspaper article related to the fire that removed this mill from the face of the earth and into the history. As the image was not very clear I will rewrite it in here below instead of showing a screenshot of it - you find the info at bottom of page.

Another year is here, and I still have tons of stuff to do, like this mill. None is done, sorry, but I have found what I think is a date for the picture below with that Prince Hohenlohe in it. Seems like the good Prince and party had a roundtrip in Colorado in summer of 1904 as I found an article about him visiting Breckenridge on his tour of Colorado! Cool to find that. :-)


Not really an update, I have put this mill aside as I got stuck on the figuring out part... :-(

But earlier this year I bought an old folder of ebay, and that had one big surprise for me, one that I was so happy to get!! :-)
Just look at the picture at right of here, don't that look cool or what? LOL

Now, to be able to make a model of this, the cars, and the tunnel and the mine/mill complexes...

Oh well, life has to turn around soon so I can get back to Cripple Creek modeling.

I found this lovely picture in an folder, seems like celebrity visited Cripple Creek, just wish I knew a year to help date this picture.  ->


I've been busy with other stuff, and been waiting for new memory for the AMD. We now have 2GB of RAM in it, 1GB stick times two from Crucial - and it behaves much better. Trainz and gmax can now be open at the same time without crash - but still I haven't had as much time as I wanted to work on the mill.
I've been doing some work the last two days, I want a working model for a project I have in my head - so I need to speed up my progress.
What I have done is add the building that cover the tunnel opening, and a basic brick box to be used as a start on the office/assayer building - as seen on far left on some of the real pictures I have.
So, to show some progress to who ever is out there reading this, here's some pictures! :-)

Compare to the model at left

For the last week I've been using this model to test out a new computer we bought on a trip to Norway we just been on. The computer is a AMD 64bit, but seamed to have some problems when running both Trainz and gmax so I've had to try figure that out.
But, this page is not about that, so, instead, latest news are that I got the book I waited for - almost missed it in Norway! Book is nice, it's old, fragile, seams to have all the maps and such - but, the small words it had about this mill, not very helpful alas... :-(
But, I've been trying my best of matching pictures and Sanborn map, but I' about to stop again as I just can't seam to be able to match is as good as I want!
Below is the pictures for today, first out is a couple of screens showing my model and it's "model" - pictures of real mill! After that, you will see some more pictures of the model and the 18" mine train I guess they used - except, it was a trolley system, the yellow engine in pictures are a battery train for lack of better...

The real Mill, compare to model at left.

And, this is the view from the train itself, coming out of the tunnel from the Gold Coin.

I have yet to model the road that was above the track, this part is mostly guesswork.

Pictures I have is not good enough to make out details, but it looks quite good...

This part I made today, as you see, the building at left is higher up then track...

I've made some doors so the workers can get in and out - and from what I can tell, their now happy... :-) Other then that, not much have happen to the mill model.
Did put a Sanborn Map on the bottom of the model, more or less scaled to the model as I couldn't get the info from my CAD program that I needed as I had removed the Sanborn Map after I traced it - therefore, no X,Y coordinates to use...
Reason I put in the Sanborn was that I had hoped it would help me place this mill better inside of Trainz - but after spending some time in there I still think it's not good enough.

Latest update on my never ending job on the Economic Mill is that I finely after nearly 8 months have open up my gmax file again and started on doing a model for Trainz!
My computer do not like to run my CAD program in 3D anymore, so I haven't actually drawn anything new - just been busy last 3 days getting the X,Y,Z info out of my CAD drawings for the windows so I could put them into my Trainz model.
As a window texture I've used a picture I took at the Western Mining & Industry Museum in Colorado Springs. The stamp mill they have there had some nice textures I just had to have a few pictures of... :-) The roof is for the moment made from a picture of a red tarpaper roof in Alma, Colorado recolored into a blackish tarpaper roof... And, walls are made from a reddish iron/metal siding picture of the Coeur D' Alene mine in Central City.
Today I hope to make a couple of door textures as I would guess the workers in the mill would like to get out once in a while and not having to crawl out the window... :-)
I will also try to put in some of the roof awnings or whatever they are caller, think I did drawn them long time ago. Other then the above mention I don't think I can get much further as I still would prefer to work from a drawing where time is spent to try match pictures as close as possible then to just spend some time in gmax just making something that's more or less correct.
After I got some weeks back an old article about a Chlorination Mill in Florence, Colorado with some drawings from that one I got a little better understanding on some of the words used on the Sanborn Map, but still, there's so much I don't know!
I bought my self a expensive book called "The Official Manual of Cripple Creek", dealing with the companies of that area in 1900 in hope of learning more - didn't find much of interest for this mill.
I also have a book in shipping dealing with the Geology of the area, according to a friend that one is suppose to have a short description of the workings of this mill + several pages about the Gold Coin Mine which this mill was connected to via the Columbine/Victor Tunnel - so I eagerly awaits the day I can have a look in that book! :-)
But, for now, I will put in some doors, fix the textures so it's proportions are more correct and then, try make my self a new mine tunnel from a short description of the Columbine/Victor tunnel and have it connected to my mill in Trainz! The left most picture under here actually shows the tunnel I use as of today as the Gold Coin connection tunnel.

Not so bad looking I think
- if you don't mind missing roof

View inside TOE of model
- roof is now made...

Same, just more fancy...

3rd PlanIt model
Economic Mill in Eclipse Gulch is my first attempt of buildings/structures of the Cripple Creek District. Mainly because from the very first picture I saw of it, it SCREAMED to me, please, please make a model of me!! J It have taken long time, but I'm about half done, making plans from pictures is not easy!
But, I recently got an old picture of the buildings that helped me make out a little more of the left side - as you can see here on the left - thanks Mike! 

From my books I have found 5 pictures, the one Mike sent me made #6 - and all 6 of them shows a different building!! Not much, but it is obvious that the Wood brothers rebuilt they're mill "all the time"...
I bet they did it just to confuse me about a 100 years later... J

Anyway, I have to use some artistic liberty since this building is long gone - it burned down early morning on the 30th January 1907 [Lowell Thomas's Victor] - but I think I've closing into capturing the feeling of this massive building! And I'm happy with that.

I started by using what I suspect is the oldest picture of the complex (Fig.3). This one shows the front very good, so I scanned that and put it into a CAD program called 3rd PlanIt.

There I scaled the picture so the windows matched some H0 scale windows I have that looked similar to the ones in the picture.
After that it was just using that size to try match the other measurements up so it at least seams to match the pictures, not always easy when you have 6 different ones...
Well, OK, they aren't that different, but it has made me confused sometimes. Anyway, Fig.4 is showing the drawing I first made.

Then, I got sick and tired of this massive work, so I took a break for a month or two. That lasted until I saw this last picture on the Internet (Fig.2) and just had to try get it. It made me feel for starting the drawing process again - and make this page your reading... J

Until today I've constructed some of the buildings in virtual H0 scale using 3rd PlanIt just so I could check that my drawing is correct. The first picture (Fig.1) is showing the model I made.
But, I've still has some more drawing to do, not to even mention the actual modeling of this massive structures in real life model and virtual model!
So, I'm back to the drawing board!

Update! - 11102003

Well, I've been working on and off for some time now - been busy trying to learn some dutch also... The main problem of hitting the wall is bugging me (again..), even with the Sanborn Fire Insurance maps on hand. Mostly it is the old problem of missing info and what to do with the walls/sides I don't see in the pictures...
The most recently problem with the Sanborn map and the pictures not agreeing with each other, have made me to almost give up on this one and just try following the pictures as close as I could, but using the Sanborn as a starting point, and as a reference point. So it is sort of turning into some sort of a caricature of what it was, not a perfect match...

Latest (11102003) development is shown here.

And, here is some older (22092003) views. The lower building (roaster building) is nearly redone like this pictures shows:

Fig.13 - View 3D from above, over the Sanborn map trace. (Pic)

Older info, Fig.5 is a scan of the Sanborn map dated 1900, I've cleaned it up since this scan, and have been figuring out measurements from it. But, even if it did answer some of my question it raised even more since this building don't match all my photo's as mentioned earlier...
And, there are numbers that I think relate to a table or something with more info, and I learned that the maps was originally made in color, but my source only has the B/W copies that was microfilmed some years ago - wish I could get hold of color copies instead...
Anyway, this pic (Fig.6) shows what I had made until my Norway trip, but since this didn't match what I have found out by tracing the Sanborn map (Fig.5), I decided to redo it. OK, it wasn't that off, more like a drawing with a scale from around 1:90, and mine was draw it in H0 scale (1:87)! J
But, some measurements where in a scale higher, like 1:93, some in 1:88 and so on, but working with just pictures I'm still quite happy I got this far.

But, quite happy is not what I want, I want perfect - even if I know there are almost no chance of me ever get to that point, but still I started to redo the drawing - even if I have to spend lots and lots of hours of work all over again...

















From Lowell Thomas's Victor:
At approximately 2 P.M., carriages picked up the Roosevelt party and drove them through a short tour of Victor. Then the group was driven to the Gold Coin Shaft House built with red pressed bricks and colorful stained glass windows. Seventy-five people accompanied Roosevelt down the main shaft of the mine to its eight hundred foot level. Mr. and Mrs. Harry Woods-still dressed in their luncheon finery-performed the honor of being Mr. Roosevelt's guides.

Harry Woods pointed out the Gold Coin vein as they traveled a quarter of a mile down the drift. In one stope, Roosevelt was handed a pick and offered the chance to dig his own ore. He happily relieved himself of his hat and coat, then started to work. The $500 worth of ore he loosened from the vein was sacked and presented to him.

The party returned to the first level of the mine and rode fifteen mine cars, headed by an electric locomotive, three-quarters of a mile under Squaw Mountain to the Woods' Economic Extraction Mill in Eclipse Gulch. The Vice-President was shown a lump of gold concentrate recently extracted from Gold Coin ore worth over $20,000.


30 January: fire consumed the Economic Extraction Mill. It was the largest mill of its kind, built in Eclipse Gulch by the Woods Investment Company in 1899 for $532,000.
The fire began at five in the morning in the main mill. Spreading rapidly, it destroyed the ore houses, assay office, and general offices. Smoke could be seen rising over the summit of Squaw Mountain from any standpoint in Victor. Then wind blew the thick smoke into the United Mines Transportation Tunnel. The smoke rose up the Gold Coin shaft and filtered into Victor.

Since the mill was not in use, insurance on the structures had not been kept up. Negotiations had been underway to convert the mill into a cyanide plant for processing gold ore. The mill was never rebuilt.


From a friend:

I can tell you this about the Victor-Columbine Tunnel: it was well-bored. When we were in it – opened by the mining company of the time specifically for our inspection – it was in excellent condition. The ceiling was 8 to 10 feet tall in most places. The width was 6 to 8 feet. There were several connecting laterals along the way from Arequa Gulch to the Gold Coin shaft. The tracks from the electric tramway had either been extracted or buried. There was a strange mold raising from the floor of the tunnel: a white stringy like plant that floated with the light breeze (created by the hole opened for us to crawl through at the top of the tunnel). This mold broke up easily as we walked through it. Of course, the tunnel was moist; and, contained a “dead-air” smell in it. It was in remarkably good shape for being near a century old. It was especially erie at the end of the tunnel, where it connected with the shaft, as one could look up (about 600 feet) to see a speck of the sky; and, down into an abyss of darkness.

It was definitely a different experience, like walking back into time. Although there were about 5 or 6 of us on the journey, I felt alone in the tunnel, cold from the high humidity, oppressed by the rock all around. My friend, Joe Vanderwalker, who had basically grown up in such circumstances – having worked in the Cripple Creek mines most of his life – had wanted the mining company to consider re-opening the tunnel as a tourist attraction for Victor, with an electric tram and mining history displays. Alas, the whole tunnel opening, as well as the ruins of the Economic Extraction Mill, are buried beneath at least a hundred feet of waste rock, which fills a good portion of the head of Arequa Gulch.


From Geology and Gold Deposits of Cripple Creek District (page 143) by Lindgren & Ransome - USGS Professional paper 54:

The Economic mill at Victor, with a capacity of 800 tons, roasts after crushing in seven Argall furnaces and one Pearce furnace, both burning crude Florence oil. The chlorination takes place in seven 20-ton lead-lined revolving barrels, 17,5 by 8 feet. Chlorine is generated by sulphuric acid and calcium oxychloride. The agitation occupies three hours. The filtrate goes to settling tanks and thence to five steel precipitating tanks 8 by 10 feet. Hydrogen sulphide is the precipitant used. After passing through filter presses the cakes of gold sulphide are roasted in shallow iron pans, mixed with flux, melted in a wind furnace in large graphite crucibles, and the gold finally poured out in 700-ounce bricks.


From a newspaper article written 1 February 1907 (Unknown paper):

Men armed with Winchesters yesterday guarded the ruins of the Economic mill on the west side of Squaw mountain in Eclipse gulch, as a protection against thieves, who are said to have carried away brass, copper and other valuable metals the day prior.
It was while men were engaged in saving what part of the property they could that it was discovered young ruffians were ransacking the ruins.

One of the youths was caught in the act and forced to relinquish his spoils and while no more trouble was given by him the rummaging continued, as did the fire.
At that time only the night watchman, R.A. Walcott, was on the ground to prevent depredations, but several more guards were on duty yesterday each carrying a Winchester rifle on his shoulder.

Frank Woods, of the Woods Investment company in charge of the mill, did not arrive from Denver, being detained on business. He is expected today.
While investigation is being made into the origin of the fire practically no tangible evidence is furnished to work on, and yesterday's effort bore no fruit.
That the mill will not be rebuilt is authoritatively stated.

From the 1904 Annual Report of the United Gold Mines Company: (If you have it, could you please help me with some info as I don't have it?)

* The track for the tunnel is laid with 35-pound rails.
* The transportation company owns ninety-five ore cars and a Morgan electric Locomotive.
* It takes less then five minutes to make the distance from the Gold Coin Mine to the mill with a 25 ore car train.
