        The Apache Agate deposit is located in a very remote part of Chihuahua Mexico. It is found on a ranch about 35 miles southeast of the city of Nuevo Casas Grandes. The deposit is reached by following winding dirt roads through the small towns of Malpais and El Apache. Past El Apache the road turns northward and goes through the ranch. The agate is found on a small ridge between an arroyo draining the mountains to the west and a much larger drainage coming from the northwest. The point of this ridge was mined by hand for many years and then with a small dozer in the early 1970’s. The Gem Shop, Inc. mined this deposit in 1995 using a front-end loader.
  Apache Agate                                                                              Apache Agate is known for its floating red colors in clear agate. It is usually categorized with the other banded agates from Mexico but is really quite different from its cousins (Laguna, Coyamito, etc.) found 100 miles to the southeast. The outside surface of the agate is generally reddish-orange, which makes them easy to distinguish from the Laguna agate, which is generally greenish on the outside. The bands are not as distinct or sharp as the other Mexican agates and the common red color is on the orange side of red compared to the Laguna agate where the reds are more of a bluish red. The red bands or stains can float from one clear band to another like ribbons or wind-blown veils, and this characteristic gives the Apache agate its distinctive look. Orange and yellow colors also occur. No pinks or purples occur in Apache Agate.
        The composition of the deposit is also unusual. The agates are found in pods or clusters very close together in hard clay. Apache Agate "fish-eye" There may be upwards of 500 lbs. of agate in one of these clusters and then no agate for 10 to 20 yards of more. The agate forms as nodules and as seams. The nodules are seldom regular and often have a bumpy irregular shape. There is a lot of calcite in the formation and most hollow nodules are filled with calcite. Some plume agate is found in the area but none in the main digging area that I know of. Both banded agate and moss agate are found in the Apache deposit. The moss agate often has the same bright red-orange color as the banded agates. Near the south end of the claim, some agate has been found with spherical inclusions around the outside of the nodule that was called "fish-eye".

1995 MINING OPERATION

          I was afforded the opportunity to mine the Apache Agate through Benny Fenn who owned the claim and worked the deposit in the early 1970s. I had visited the site several times and found several engineering problems with the deposit. One was the lack of a water drainage system and the other was the lack of space for overburden. Both of these problems made the use of a dozer to work the area impractical. So I was thinking of moving my front end loader from Oregon to Mexico to do the work.   Much to my surprise, a front end loader located in Lordsburg, New Mexico was offered to me for sale, so I bought it  and moved it to Mexico (a story in itself, not to be told here). 

             
This was my first attempt at mining in Mexico, and let me say that in the beginning, it was a complete failure. Front-end loader There were many problems right from the start. The truck hauling the machine was able to get within about 4 miles of the deposit. This was after 30 miles of dirt road. From here it was necessary to "walk" the machine cross- country through an arroyo to the agate site--not a long distance for many claims. The rancher allowed me to go through his fence and even cut a path through some Mesquite to get me started. While driving the loader through the ravine, it got hung up on a sand hill and the motor stalled. It would not restart. So there I was, broken down in an arroyo, 1 mile from the nearest dirt road, 30 miles from the nearest paved road, in a foreign country where I only knew a few words of Spanish. Not a pleasant situation. In a day or two, through the help of Benny, we were able to get a mechanic out to the machine. In the U.S. to get a mechanic to come to you is not easy, and to have a mechanic drive 30 miles on a dirt road and then cross-country on no road, is next to impossible. But not in Mexico. Mechanics in Mexico have the reputation of being able to fix anything and soon bolts were flying off the machine like rain. Still, what was wrong could not be determined and the young mechanic said he was going back to town to get his father. The next day the old man got out of the pick up truck, sat in the sand and asked several questions as the son lay under the machine with his hands up the the guts of the engine. He figured it out in 5 minutes and  never touched a wrench.   A sleeve bearing on the side of the crankshaft had slipped and jammed not allowing the engine to turn. Another day and it was fixed--2 mechanics, 3 days, driving 40 miles (about 2.5 hours) each way and the bill was??? He wanted $150 for the whole job! I gave him $400 and we were both happy.

When the Apache was mined in the 1970s, a small dozer was used. Overburden was pushed out and away from the pit in a circle.  This created a large dam and subsequently water coming down the small arroyo filled the hole with water. The deposit is full of clay which simply holds the water and it will not drain away. Eventually the main digging area was covered with about 10 feet of mud. I  had consulted with two geologists and several people who had worked theLack of drainage creates a water-filled pit. deposit before about where to work. They all suggested working in the back into the hill. This is exactly what I did for 3 weeks and found only small signs of agate. During this time I also managed to break a fan belt, have one of the tracks come off, and get stuck in the mud. I decided to do a little experimental digging in different areas with the little time I had left. I moved to the front the deposit about 50-75 yards in the other end of the main pit. In one and a half days, I hit a group of agates all lying very close together. One bright red band on the outside and filled with calcite--not one keeper in the 700 lb. batch. I moved over a little further and soon hit another pod. This one had good quality rock, but not like the agate from the original pit. At least I was able to come back with something.

 

      

 Pictures of the Apache Agate mining area

   The Apache Agate claim is located on this ranch.

 

   In this photo we are looking northwest across the digging area.  Claim markers can be seen on top of the ridge.

 

   The front-end loader is seen in the upper left of photo, resting above the area that was worked for about 3 weeks, but produced no agate. 

 

   Many small orange colored pieces and chips of Apache Agate lay on the ground across the area.

 

   The flat area is this photo is covered with a thick layer of mud which was almost hard enough to walk on at that time. During the mining operation (out of camera range to the right), overburden was pushed over the ridge and caused the mud to flow similar to a lava flow.
