The Verde Combination mining claim is less than one air mile from the town of Jerome and the old, deep mines of Jerome. The Verde Combination is documented to be owned and developed by Verde Combination Copper as late as 1919. The mine is noted to intercept the Revenue vein and the Verde many other drifts and tunnels. There are no other known portals that surface except for the adit and the shaft on the claim.
The shaft has been historically known as the Cliff Shaft, and the adit has been known as the Gorge Tunnel. In later years (1920-1960) the mine was referred to as the Green Monster collectively.
It is assumed that this group of workings intercepts the Verde Combination (Cliff) shaft, but it is unverified due to a drift inside that is blocked by slough.
There is good road access to the portal of the mine but short wheelbase, 4-wheel drive and some technical skills will be required due to challenges on the trail. Most notably are off camber turns and washouts.
The Verde Combination claim is set in the high hills adjacent to the historic mining town of Jerome, Arizona. Much of Jerome and the surrounding mines is and has been private for many, many years. The area is known for its deposits of copper, silver, gold and lead. The Verde Combination was so named for the Verde Combination company who originally located the mines. The company was sold to, and held by the Green Monster Mining Company for many years in various incarnations.
The Verde Combination is roughly 3 miles south of the town of Jerome. The shaft is historically documented to be 930′ deep with a drift at the 500′. Over 2000’ of drifting on that 500′ level. In addition, an adit less than 1000′ west of the shaft is documented at over 800′ with values of gold, silver, and some copper. Because of its lineage, the mines have been referred to as the Green Monster or the Verde Combination.
The Verde Combination has limited public history available. It is noted in 1923 as being a 900′ shaft with 2000′ of drift workings. The mine was noted to be producing gold and silver in a chalcopyrite type ore. In 1923 the ore was assayed at $75 per ton in gold and $100 in silver. Roughly, that’s 3-3.5 ounces of gold ($20 per ounce) and 153 ounces of silver (.65 per ounce). At some point in the 1930’s it was taken over by the Green Monster Company. It was renamed the Green Monster and an adit was cut on the north side of the mountain that chased the Verde Fault. It is assumed that this group of workings intercepts the Verde Combination shaft, but it is unverified due to a drift inside that is blocked by slough.
This drift is plugged with slough at what the surveyors assumed to be 50′ away from the intersection with the shaft. It would take some effort to remove the muck and re-open the drift. It would provide easy access to the shaft and the workings therein and likely be quite close to the drift at the 500′ level.
There is a large platform that was used for winches and air compressors above the main shaft. These footings are consistent with the era of mining reported. The equipment was likely moved to another mine as there are no remnants of the headframe, or any of the machinery. It is always possible that the headframe and the machinery were pushed into the shaft and may be found at the base of the workings.
The roads to the site are well defined, and the route from the south is the only accessible path of access. 4WD is mandatory for steep and narrow roads with some off camber sections. The road is open, but has some technical sections. This has kept most vehicles and UTVs from accessing the site. Once at the claim, there is ample room for staging gear and machinery for processing.
The town of Cottonwood is at the base of the mountain and offers all of the amenities that could be required.
