Opal Hill Mine

Mule Mountains - California

 

By Dusty Rhoads

Tucked deep into the Mule Mountains not far from Palo Verde is the Opal Hill Mine. Opal Hill is well known for its beautiful and rare fire agate, opal eggs and quartz crystals. When one thinks of a mine, images of deep shafts or dark tunnels usually come to mind. The Opal Hill Mine can be better described as a claim established on a hillside which overlooks a valley. The mine consists of rock outcroppings and holes where agate has been extracted. The claim was abandoned/forfeited in 9/1/2011; it has now been reclaimed and there will be fee for digging there.

The mine is on a hillside.

Opal Hill Mine is actively producing fire agate, and rock hounders still frequent the mine for its gem-quality stones. The mine is privately owned but may be open to the public for a fee. With some hard work and effort, almost everyone leaves Opal Hill satisfied with the fiery agate they take with them.

Opal Hill Mine History

The mine was managed by Helen Madden as a pay to collect site beginning in 1965, and continued that way for 18 years. The BLM had wanted the area managed and Helen was ideal for the job. She was an ex-merchant marine who was about 4 foot 7 inches tall, and she ran the collection area with an iron hand.

Madden sold the claim in return for five gold claims and $10,000 in the early 1980s to Louis Meserole, who asked his partner Nancy Hill to run it for $500.00 a month plus collection fees. Nancy fell in love with rockhounding and continued to work the mine for another 27 years with husband Howard. In 2011 Nancy left the claim.

Over the years desert heat, vandalism, and even a tornado has taken it toll on the camp area, leaving it in total destruction. The new claim owners and working on plan for reopening the area to recreational rockhounds.

When we visited the Opal Hill claim back in 2010, Howard Fisher and Nancy Hill greeted us with open friendliness and made us feel right at home. They lived at the mine for many years and had created a cozy homestead at the entrance to the mine. That area has now been destroyed -- see the picture below.

 


 

Since we had only stopped by for a brief visit and not a dig, Howard gave us a short tour of the mine and an overview of the types of gemstones commonly found there. During the tour we stopped at a site where he was currently working on an agate-bearing vein.

Removing the fire agate from the surrounding rock takes some work with a sledge hammer, chisel and pick. Howard demonstrated how to find an agate-filled vein and then gave us some helpful lessons on how to remove the agate from its resting place. He explained that agate is a type of quartz called cryptocrystalline, also referred to as chalcedony, which is formed from masses of fibrous or granular aggregates of quartz. Agate is one of many varieties of chalcedony and can range in color from banded patterns to the rare fiery red.

Howard and Nancy showed us colorful samples of fire agate which were found in the mine. "Fire" describes the red color of the stone. Once extracted, agate needs to be cut and polished or simply polished in its natural form to bring out the brilliant color. When the agate is polished and then viewed in the light, flashes can be seen. Petrified wood, apatite, barite, calcite, clinoptilolite, flourite, and gypsum have also been found there.

Opal eggIf you visit the mine, plan to stay a full day or longer. It takes some time to find a good spot to dig, and once you find a spot you'll need time to extract the agate. If you only want to spend a few hours, there are a few bits of agate to be found in the tailing piles and dumps left behind by others. You can find some beautiful treasures without the hard work and labor of digging out a vein.

You should have a 4-wheel drive vehicle if you go to the claim, the road is rocky and difficult in some places. We last visited the mine in 9/7/2016 -- we made a short video of the visit.

Visiting the Site

At this time there are several claims that have been files on the Opal Hill Mine since the claim was abandoned/forfeited in 9/1/2011. The new claim filers /owners are in negotiation on the the future of the claim, with the goal of keeping the area open for recreational rockhounds with a digging fee. Once we have more information we will post it here.

Location

From Interstate 10, take Wiley Well Exit and head south on the graded dirt road for 11.86 miles. A dirt road leads to the claim; it's no longer marked. (If you pass the entrance to the Coon Hollow Campground going south you've missed the road.) Go east on the cut off road and travel for a about 2.3 miles on the rough dirt and rocky road. A high clearance 4x4 vehicle is needed to navigate the last mile of rocky road to the mine. GPS 33°27'08.0"N 114°51'53.5"W
