At the consolidated court hearings held in San Bernardino County in California on May 1, Judge Gilbert Ochoa heard arguments from attorneys David Young and James Buchal on behalf of the miners. He had already received all the supporting documents and arguments from each of the involved parties. One of the key questions Judge Ochoa asked of attorneys representing the State of California was if they could provide a date when the current moratorium will end. The answer was, "No, Your Honor."

Approximately 120 miners were present to lend their support. Judge Ochoa initially announced he would issue his ruling in about two weeks. However, after most of the miners left the court, the judge called the litigants into his chambers. In a closed-door meeting he ordered the involved parties to participate in mandatory settlement hearings, which he scheduled for June 24, 2014.  The judge also set aside two additional days -- June 25 & 26 -- if needed.
 
Let me explain why this is good news. Mining law and case law are in favor of the miners.  We've always known this, we just needed a judge with the guts to stand up to the State of California and their environmental cronies. There is plenty of case law which dictates that the State of California can regulate mining but cannot prohibit it. The current moratorium is, in fact, a prohibition.
 
If Judge Ochoa was going to rule against the miners he would have left the "about two weeks" schedule in place, or he would have made his ruling on May 1. By ordering mandatory settlement hearings he is providing the State of California with the opportunity to try to at least gain some concessions from suction dredge miners.
 
All the plaintiffs are required to participate in the settlement hearings and must negotiate in good faith. If no agreement can be reached, then Judge Ochoa would have to rule on the merits of the case.
 
We have confidence in PLP (Public Lands for the People) and the attorneys representing the miners. They have been down this road before. It's been nine years since the latest round of court battles began and five years since we've been able to dredge legally in California. We should be back in the water soon.

The abbreviation kHz stands for ”kilohertz” which is the measurement of radio frequency radiation. A Hertz is the unit of measurement for counts per unit of time. Frequency is the number of occurrences of a repeating event per unit time. The higher the frequency, the more waves travel through space during a given time
frame.

There are two general types of metal detectors: Pulse Induction (PI) and Very Low Frequency (VLF). The major difference between PI and VLF is the ability for the machine to discriminate targets. Keep in mind that a detector does not actually detect metal directly. It detects magnetic fields. A detector “hears” the waves of electromagnetic radiation or radio frequency radiation through a coil. When switched on, a VLF detector first creates a magnetic field and energizes anything in the ground that responds to a magnetic field. Next, your detector seeks to find a magnetic field that has a response to its initial magnetic field. Because metals conduct electricity, they respond to a magnetic field and generate a small magnetic field of their own. Detectors detect the secondary magnetic field that conductive targets create whey they are energized by the first magnetic field sent into the ground by your detector. In general, the larger the metallic target, the larger and longer and stronger its magnetic response will be.

PI (pulse induction) detectors work a bit differently by putting magnetic field energy into the ground and then switching off and waiting a short period before they start to look for a response. This makes them better at handling ground mineralization than a VLF machine because during that short delay the magnetic response of iron trash minerals that you don't want to find dies out, but the signal from tiny bits of buried gold does, too. VLF detectors are more sensitive to finding the smallest bits of gold, but do not as easily cancel out ground mineralization.

If you've been shopping for a metal detector, you might have noticed that the manufacturers list the kHz of each machine. But how do you know if a higher or lower frequency is better? In most situations, a few kHz one way or the other will have a negligible impact on performance out in the field. The importance of frequency is most noticed when you are hunting for one particular type of treasure over another. For example, if you are coin shooting at the park, you can opt for a lower frequency metal detector which will cost less. However, if your main objective is to find gold nuggets with your detector, consider a higher frequency machine such as the Fisher Gold Bug 2 or Garrett AT Gold.

Typical winter storms that regularly occur in gold country usually do not create enough havoc to force substantial amounts of "new" gold into movement. However, when major flooding like what happened in Colorado in September of 2013 is followed by a “bad” winter, a great deal of gold can be set free. When tons of rock, cobble, and boulders are swept downstream along  bedrock during a huge storm, quite a bit of destruction occurs. Plants,  weeds, and trees that normally grow along the river and gravel bars are  washed away. And when a major storm or flood tears up large portions of a streambed, a fair amount of this newly-released gold, because of its weight, will be deposited along the riverbed and settle into cracks and crevices.

Stream bed layers caused by several floods are referred to as “flood layers.” Flood layers are usually a different color, consistency and hardness from the other layers of material within the streambed, making them easy to recognize. Larger, heavier pieces of gold will work their way down toward the bottom of a flood layer as they are washed downstream. The smallest and lightest flakes of gold might not work their way down through a flooding layer at all, but might remain dispersed within the material. Of course not all flood layers contain gold in large quantities, but it’s a good place to start.

Some of the best areas to look for flood gold are where the stream or river widens out, or levels out, or changes direction. These areas can allow concentrations of gold to collect either on bedrock or in the contact zones between layers. Another place that tends to collect gold are gravel bars, especially the ones located towards the inside of bends in a waterway.

No one ever hopes that Mother Nature releases the type of fury that causes loss of life and property, but when a catastrophic weather event occurs in a gold-bearing area, take advantage of it. Get out there and get your share of the GOLD! Good luck and be safe!

Some say that "gold is where you find it" and while that may be true, once you arrive at a known gold-bearing location, how do you decide where to dig first? Successful prospectors follow different methods, so there is no single "right" way, but no matter if you are sluicing, dry washing, or metal detecting, if you first consider the "lay of the land" you can better pinpoint a place to start.

Natural Factors to Consider Before Digging for Gold:

• Types of Placer Deposits. Alluvial, residual, beach, and other types of placer gold are all worked differently. Alluvial gold forms in streams. The gold tends to concentrate on bedrock as it moves downstream and makes its way down through the gravel to bedrock. Residual placers form on the surface as rock materials weather and are washed or blown away and do not concentrate on bedrock. Knowing the type of placer makes a big difference as to where you should begin to look for it.
• Quartz Veins. Gold often forms with quartz, so quartz veining can be a very positive sign. Quartz is very resistant to weathering, so it may hang around on the surface long after any nuggets have sunk below the soil. If you find a visible quartz vein outcrop, that can be a good sign. The outcrop, as well as any areas downhill from it, should be sampled. Also remember that not all vein quartz is white. Some can be stained red-brown from iron.
• Iron Staining. Not all gold-bearing mineral deposits contain quartz. Gold-bearing veins can consist of calcite or mostly sulfides which often weather into iron-stained spots as the pyrites convert to iron oxides. While quartz is often a good indicator, it is not necessary for the formation of gold nuggets— but sulfur is necessary. In places where gold occurs with quartz, there is often a lot of iron, which was once (before it was oxidized) a sulfide such as pyrite. Any gold that was formed in these deposits is left in the red soils that remain, or perhaps nearby. The red soils can be deep orange or red-brown or brick red.
• Favorable Rocks. The type of rock considered "favorable" will vary greatly based on the area. The same "favorable" rock in California may not be the same "favorable" rock for finding gold in Alaska. In some places the best rock to look for might be schist or slate, in other places it might be volcanic. In general, sedimentary rock is usually not a favorable host rock for gold.

Man-Made Factors to Consider Before Digging for Gold:

The sites of small, old-time mining operations can be some of the best places to look for gold. After all, the old-timers didn't have the modern-day equipment that you have, so they left a lot behind. Depending on their age, these sites from yesteryear can be overgrown, but if you look for these indicators they will help you consider where to dig first:

• Ground Cuts. These are narrow trenches in the ground that carried the gravels to the sluice box.
• Rock Piles. Sometimes old-timers encountered rocks that were too large to pass through their sluices under the water pressure they had to work with, so bigger rocks were picked out by hand and tossed aside. Piles of rocks make an easy marker. Any quartz you find in rock piles should be checked with a metal detector— you might find a gold-quartz specimen that's worth a pretty penny. Rock piles can be visible in the desert as well. Although the old-timers were not sluicing in the desert, they used dry washers that had to be screened for coarse rocks. If you see a series of short rock piles a few feet in diameter that cover an area that seems to have been dug out, you can reasonably assume you have found an old dry wash site.
• Hydraulic Mine Workings. A sign that an area has been worked by hydraulic mining are the steep banks left behind when the gold ran out (or so they thought). These sites are also commonly marked by piles of big stacked rocks.
• Shafts. Miners sometimes dug deep shafts or adits to access gold veins. These working are usually easy to spot even today. If the dumps consist of rounded gravels, it is most likely from underground placer diggings. If the dumps contain angular broken rock, that would indicate blasting from lode mining.

Deciding where to dig first comes from knowledge. You get that knowledge from reading books and magazines dedicated to prospecting and metal detecting, talking with experienced old-timers, and GETTING OUT IN THE FIELD. Evaluate the area, think about the geology, and then make a plan before you dig. You may not always hit upon a promising location by considering the factors listed above, but your chances for success greatly increase. Be flexible, keep sampling, and try again if you don't have any luck at first. Spending a little time evaluating an area can lead to a much more productive hunt, because after all, "gold is where you find it."

Among the many improvements made to mining technology during the Industrial Revolution, perhaps the most important involved drilling and blasting. In the early days, black powder, a relatively low-power explosive was the only blasting agent available. To use it, holes had to be pounded into rock by hand. Working in teams of two, one miner would hold a pointed steel chisel while the other hit it with a sledge hammer. Each hole had to be hand drilled to six or eight inches in depth. Needless to say, this was slow, tedious, and tiring work. During a 10-hour shift, a team could typically drill, load, and fire black powder charges in only eight or 10 holes. Depending on the size of the mine tunnel, that single blast could bring down three quarters to two and a half tons of rock.

Dynamite, an explosive five times more powerful than black powder, was invented in 1866 by Swedish chemist, Alfred Bernhard Nobel (the Nobel Prizes awarded today were named after him). Nobel held 350 different patents; dynamite is his most famous claim to fame. By the mid 1870s, dynamite had largely replaced black powder in the mines.

Around the same time period, pneumatic machine drills were first developed. Compressed air to power the drills was piped underground from large steam-powered compressors located at the surface. Machine drills could accommodate five to six foot drill steels that were capable of drilling three to four foot holes into sold rock in a matter of minutes. This new drill increased the tonnage of rock that could be blasted by two-man teams of miners to between four and 10 tons per shift. But, the new technology was not without hazards— namely the disease of silicosis. Machine drilling created clouds of razor sharp microscopic silica dust that miners breathed into their lungs. It took only a few years of operating this drill for a miner to develop this incurable disease. 

Unfortunately, thousands of hard rock miners died before J. George Leyner of Denver, Colorado invented a better machine drill that all but eliminated deadly silicosis. The improved drill forced water into the drill hole and created a harmless mud out of the drill shavings. The mud acted as a very efficient wet grinding compound while also cooling the drill bit, and the flow of water flushed out the drill hole. Leyner patented his mechanism in 1897. This type of drill hasn’t changed much over the years, and is still used in modern-day hard rock mines.

According to a recent article posted on foxnews.com, a mining supply company located in Auburn, California reported that business has been up by 10 percent. The boon in business is because in Placer County, rivers have dropped to historically low levels, opening new possibilities for prospectors.

"Stuff that's normally submerged in water is now available," said James Hutchings, Sacramento chapter president of the Gold Prospectors Association of America. "The exposed cracks and crevices can hold chunks of gold that have washed down from the mountains."

If you are heading to Auburn hoping to spot something shiny, also take some time to enjoy Old Town and learn the area's rich gold mining history. California State Highway 49, also known as the Gold Rush Highway, winds its way through a nine-county area that in the mid 1800s was home to more than 2,500 gold mining camps. Most of those camps disappeared after the gold ran out, but a few communities survived and even thrived. Auburn is one such city.

Auburn was put on the map in 1849 by Claude Chana, who is credited with making the first gold discovery in this area. The Frenchman originally worked as a cooper for John Sutter when James Marshall discovered gold on January 24, 1848 in nearby Coloma, the birthplace of the California Gold Rush. Like many other men bitten by the gold bug, the Frenchman quit his job at Sutter Mill to search for the shiny stuff. But unlike many men, his gamble paid off and he quickly recovered $25,000 worth of gold in Auburn Ravine. Chana is memoralized by a monument you’ll see upon entering Old Town from Interstate 80. The sculptor, Dr. Kenneth Fox, was a local dentist in Auburn and is famous for his large concrete statues.

By 1860, Auburn was a substantial city with a population of about 1,300. Many gold miners using sluices and rockers made $1,200 to $1,500 a day here. Today, the population is about 13,000 and most residents are not prospectors, they are store owners or attorneys, or work at the county courthouse. Although fires swept through Auburn’s wooden buildings in 1855 and 1857, many businessmen rebuilt using brick and those are the buildings you see today. Nearly all of these historic structures are still used, many functioning in new ways and housing contemporary businesses.

There are over 60 restaurants, taverns, antique shops, art galleries, and unique specialty stores in Old Town. Check out the irregular shaped post office on Lincoln Way. It dates to1857 and was built directly over a branch of the Auburn Ravine (a stream still flows directly below). This post office is the oldest one in California housed in its original building, and is also the oldest continually operated post office west of the Mississippi.

If Old Town seems vaguely familiar to you, it’s because it was featured in the 1996 film Phenomenon starring John Travolta, Kyra Sedgwick, Forest Whitaker and Robert Duvall. The crew filmed for a month in the fall of 1995 on Sacramento Street, as well as at places such as a bar, apple orchard, county courthouse, a park, and a lawyer's office.

Roughly 125 million ounces of gold were taken from the hills in California’s famed “Gold Country” during the Gold Rush. Auburn was lucky in that it survived the boom and bust cycles typical of early towns. Conveniently located at the junction of Interstate 80 and Highway 49, it’s easy to stop in and experience a bit of its golden history.

Before becoming one of Auburn’s most famous attractions (corner of Lincoln Way and Commercial Street), this 1891 red and white firehouse was home to the Auburn Volunteer Fire Dept., one of the oldest volunteer groups west of the Mississippi. Organized in 1852, this group is still fighting Auburn fires.

The Placer County Courthouse at 101 Maple Street was completed in 1898 and is listed on the National Register of Historic Places. It also houses a FREE museum that presents an overview of Placer County history and a nice collection of Native American artifacts. One of the best exhibits is 194 ounces of raw gold mined from Placer County soil.

Known as the Joss House, this structure at 200 Sacramento Street in Auburn, California was built after the fire of 1855. It served as a temple and house of worship for the area’s Chinese population. In the 1880s, this block of Sacramento Street was known as “Chinatown Hill.” The Chinese concentrated here and operated laundry shops, opium dens and card rooms. Brewery Lane, just north of the Joss House, was the entrance to Auburn’s “red light district.” During the district’s illustrious history, a pious man seeking to burn out the ladies also unfortunately burned out some of the Chinese settlement.

For thousands of years, humans have been prospecting, mining and refining metals. The invention of smelting was a true technological advancement for mankind and marked the end of the Stone Age. Working with native metals such as copper, silver, gold, lead, and tin came first. These metals have fairly low melting points and the ability to cast and forge them was revolutionary. The Bronze Age was born when tin was mixed with copper, creating the first alloy and better weapons of war.

As the centuries passed, metallurgists tried to figure out how to smelt iron. Iron doesn't occur in its native form and melts at a far higher temperature than any of the metals that had been smelted previously. By developing an ingenious process, iron was at last smelted, forged, and put to good use. Thousands of years have passed since the Iron Age began, and since then many exotic compounds have been created to support our quest for better and better technology.

Whether you've recovered natural gold (nuggets, flakes, wire gold, pickers, flour gold) or have unwanted jewelry or beat up old coins, you can smelt these at home. Choices for doing so include a small but high-powered electric furnace, a torch, or a small portable melting kiln kit you can also take into the field. To get started, you will also need basic gold smelting supplies such as flux, crucibles, tongs, ingot molds, and safety equipment.

Professional mining companies recover gold and other precious metals in quantities sufficient enough to pay refiners to do the smelting for them. But now you can smelt or melt your own gold, silver, and other metals at home!

Dry washers are like highbankers except they do not use water to recover gold. While wet processing is nearly always faster and more efficient, especially for fine gold, dry washers are the best tool for recovering gold nuggets, pickers, and flakes from dry materials in the desert or other areas where water is not plentiful.

Drywashers are operated by shoveling gold-bearing gravels into an upper box which is covered with a screen. The larger rocks that are too big to pass through the screen slide off. Gravel small enough to go through is fed down into the lower gold recovery box, which is an inclined trough with cross riffles much like a sluice. The bottom of the recovery box consists of a thin, light-weight porous cloth. Beneath the riffle box is a blower that pulses air up through the cloth. The vibrations and air flow, combined with the shaking and classifying action of the dry washer allows the gold to settle to the bottom where it is captured in the riffles.

Keep these tips and tricks in mind when using a dry washer:

• Moist soils and clay cause problems, so be sure to crush lumps of clay and dry your dirt in the sun (plastic tarps are ideal) before running through your dry washer. Surface soils might seem dry, but if you dig down a few inches, you may find moisture in the soil that will cause your sand, gravel, and gold to stick together.

• Double-check all the "throw away" rocks. Scanning them with a metal detector is a great way to ensure you're not tossing aside gold-laden rocks. Also, don't assume old tailings piles have been totally worked out. This is  another time to use a metal detector because ordinary rocks could be  laced with gold and completely over-looked by earlier prospectors.

• Consider using a dry gold vacuum to clean out crevices in bedrock. Feed the material that you sucked up into your vacuum bucket into your dry washer.

• Drywashing can be a very dusty process, so try to stay upwind as much as possible and wear a dust mask.
• Do a clean up every couple of hours, or after processing roughly one to two yards of material.

If you've been prospecting for gold using a pan, sluice, highbanker or other traditional piece of equipment, there's another tool you may want to consider— a metal detector. Gold detectors are not necessarily higher in cost than an all-purpose detector, but they are built with a higher sensitivity to pinpointing pieces of gold, and have better ground balancing and discrimination abilities.   

If you're not familiar with metal detecting, the first thing you should know is that your detector does not actually detect metal directly. It detects magnetic fields. When switched on, your VLF (very low frequency) detector first creates a magnetic field and energizes anything in the ground that responds to a magnetic field. Next, your detector seeks to find a magnetic field that has a response to its initial magnetic field. Because metals conduct electricity, they respond to a magnetic field and generate a small magnetic field of their own. Detectors detect the secondary magnetic field that conductive targets create whey they are energized by the first magnetic field sent into the ground by your detector. In general, the larger the metallic target, the larger and longer and stronger its magnetic response will be.

PI (pulse induction) detectors work a bit differently by putting magnetic field energy into the ground and then switching off and waiting a very short period before they start to look for a response. This makes them better at handling ground mineralization than a VLF detector because during that short delay the magnetic response of iron trash minerals that you don't want to find dies out, but the signal from tiny bits of buried gold does, too.
