Colburn Mill [aka Colburn-Ajax, aka Ajax Mill]

down on the page. Sorry to have wasted your time/ear to listen to this, I was just trying to get a layout work like I wanted.
This page has a total of 5 images, as of 05.02.2023 (21:19:03).
Most Recent added/changed image is on top.
This postcard view focus on the Ajax Mine Operations. From the large sloped structure at upper left which is the main structure of what was called the Colburn Mill, aka Colburn-Ajax Mill, to the Ajax Mine itself seen almost at the right-hand side, with its large Shaft house and orehouse. This is on the south slope near top of Battle Mountain at Victor, Colorado, in the Cripple Creek District. In the background right is seen part of Portland No. 1 Mine, and Portland No. 2 is hiding against the sky in the smoke above the Ajax Mine structure.
   The mill was built in 1911, but seems to be gone by the time the Sanborn Fire Insurance people visited the area in preparations for the last set of Fire Insurance maps in 1919 as I have not found it on any such map. I've seen not many images of this mill, but the few I have seen shows that the smaller mill structure between the large sloped one and the mine itself, that structure grows in size over the time of existence, in this view it is how it originally was built. I think, from reading a text description, that this was the Sampler/Crusher for the mill, with a covered belt conveyor running on the ground connecting it to the upper part of the mill.
   In addition to the various structures seen in this view there is also shown two aerial tramway towers used for operating the dump, most likely both for scooping it up in the original setup and later for dumping from the mill as I seen text description of the mill giving me that impression.
   A lone boxcar is parked along a spur from the 3-foot narrow gauge Golden Circle mainline passing this operation in front of the boxcar. Houses linked to the Ajax is on the slope and various water tanks are seen also on the slope.

Source of image was not in good quality sadly, but it is what it is, I have worked with it as best as I could, I've twisted the view in form of rotating/straightening it so the structures look nice, and I therefore had to crop it. The image came with an Advertisement for the Moore Filter Company, found on the backside of the source journal.
   The large sloped structure shown is called the Colburn Mill, aka Colburn-Ajax Mill, and was built on south slope near top of Battle Mountain at Victor, Colorado, in the Cripple Creek District. Located on the Ajax Mine grounds, it was just west of the mine, the mine itself would had been visible if we could have turned the view about 90-degree to the right.
   The mill was built in 1911, but seems to be gone by the time the Sanborn Fire Insurance people visited the area in preparations for the last set of Fire Insurance maps in 1919 as I have not found it on any such map. In the background mining operation at the Coriolanus Mine are seen, but I do not know if all those shafts seen are part of that mine or if there are others I also need to link it to, I assume the latter though.
   I did procure the colored version of this image as I think it is nicer. Source is gray-toned, or in common speech black & white. Used an online service and tweaked and worked with image to get what looks best to my eyes for the moment.

This view near top of Battle Mountain show a scene around the Ajax Mine where part of the Ajax Mill is seen as a structure at far left, partly visible, then lot of various structures follows as eyes walk right on the image. The Ajax Mine is about 1/3 in from right hand side, having the Portland No. 1 at its right and the Portland No. 2 about middle top of image.
   This been a popular view by Julia, as by last check of my database on July 1, 2022, I counted/know of 12 uses of this scene for various postcard editions/crops and postcard folders.

Image is for some reason marked as being the Cresson Mine, in reality it is the Ajax Mill at the left, and the Ajax mine more to the right of the image. No idea why it is called the Cresson in this view.

This sadly very bad view at the aerial tram at the Ajax Mine and Mill, show how they is storing the tailing in a deep gulch behind a dam of waste rock from the mine. The dam is being built by means of the aerial tramway dropping rock where needed for the purpose.
