Looking to strike it rich by finding gold in desert washes?
Prospecting for gold in small washes and tributaries can be a great place to start, especially in areas with old hard rock prospects in the hills.
By searching for exposed bedrock or thin gravel overburden, you can take samples directly on the bedrock, loosen any gravel with screwdrivers, アイスピック, そしてノミ, すべての砂利を慎重に集めます.
硬い毛のブラシやコードレスのショップバキュームを使用すると、金の大部分が見つかる最後の砂利を掃除するのに役立ちます.
金検出器による金の検出 岩盤上の浅い砂利のある小規模な洗い場にも最適です。. 慎重にサンプリングして検出することで、ドライウォッシャーで効果的に作業できるゴールドパッチを見つけることができます。.

Finding Gold in Small Washes
小さな洗い場や支流は、金探しを始めるのに最適な場所です。. 露出した岩盤や薄い砂利の表土を探します。, 岩盤上で直接サンプルを採取します.
ドライバーで砂利を緩めます, アイスピック, そしてノミ, すべての砂利を慎重に集めます. 硬い毛のブラシまたはコードレスのショップバキュームを使用して、最後の砂利を掃除します。, ほとんどの金が見つかる場所.
Using a gold detector can also be a great option in small washes with shallow gravels on bedrock. 慎重にサンプリングして検出することで、ドライウォッシャーで効果的に作業できるゴールドパッチを見つけることができます。.
Exploring Elevated Gravel Bench Gold Deposits
Scan the slopes above the wash for areas where sections of gravel have been left behind as the wash has been eroded deeper.
These areas are also great places to use a gold detector. But be cautious when sampling benches, as you do not want to put yourself downhill from a possible collapse.
Revisiting Flood Gold and Flood Layers
Flood gold and flood layers can re-accumulate in areas that have been worked in the past. Since most of the old desert mining districts were worked by many men over many years, the last of the real mining efforts in the desert placer areas were carried out with drywashers during the depression era of the 1930s.
That means 80 また 90 years of flooding and erosion have taken place since. 一部の地域では, especially the smaller washes, the gold patches and pockets have been at least partially replenished.
Scouting Pediments for Gold
Pediments are broad surfaces or sloping plains of low relief that are often found in arid desert regions along the base of mountain slopes. Pediments may contain a layer or several layers of gravel that have paying amounts of gold.
Pediments should be scanned with a gold detector as coarse gold may be found near the surface in some areas. Deep pediments are sometimes underlain by older dry washes called paleo-channels. These channels rest on bedrock and were sometimes worked by the old-timers using a method called drift mining.
Cracking the Code of Large Desert Washes
Large and main desert washes also contain gold, but they are often difficult to prospect due to the many feet of gravel on top of bedrock and the fact that water flows in flash flood conditions, meaning gold has no way to concentrate and will be widely scattered throughout the wash.
でも, you may be lucky and find areas where the slope of a wash changes from steep and narrow to flat and wide, such as the mouth of a canyon. There have been occasional large nuggets found by gold detectors in main washes that drain some mining districts.
Tertiary Rivers: The Mother Lode of Gold
ついに, some of the richest gold-bearing gravels are from ancient tertiary rivers that flowed millions of years ago. When prospecting desert washes, keep your eyes open for patches of waterworn gravel and rock in areas of angular detritus.
These small sections of gravel may be remnants of ancient tertiary rivers and could contain some of the richest gold-bearing gravels.
4 Methods for Prospecting Gold in the Desert
If you’re looking for gold in the desert, you’ll need more than just a pan and shovel. To increase your chances of success, it’s important to know the right strategies for the job.
下, four effective methods to help you prospect for gold in the desert.
Metal Detecting: The Thrill of the Hunt
Metal detecting is one of the most popular and thrilling methods of searching for gold in the desert.
In states like Arizona and Nevada, metal detectors are still used very successfully to locate gold nuggets.
With no need for water, modern gold detectors have gotten quite good in recent years.
For gold prospecting in the desert, you need a metal detector that can detect small flakes and nuggets of gold and handle the harsh and rugged terrain.
の Minelab GPZ 7000 is the top option for finding gold flakes and nuggets, 一方、 Minelab Gold Monster 1000 is a more affordable choice with high sensitivity and automatic ground balancing.
の XP ORX is a good option for those on a tight budget, as it is highly customizable and has a frequency range ideal for finding small gold nuggets.
Drywashing: The Desert Prospector’s Essential Tool
Drywashers are an essential piece of mining equipment that every desert gold prospector should own.
Rather than using water, they use vibration and air pressure to move material and allow gold to settle out of the gravels.
ドライ洗濯機の回収率は他の方法ほど良くありませんが、, 多くの乾燥した場所では、それらが唯一のまともな選択肢であることがよくあります.
Crevicing: The Slow and Steady Method
裂け目は、砂漠で金を見つけるための時間はかかりますが効果的な方法です. 基本的な手動工具を使用して、岩盤の亀裂を慎重に除去する作業が含まれます。, その後、収集した濃縮物を取り出します.
大量の素材を処理できない場合もありますが、, 亀裂形成により、微細な金が充填された高品質の濃縮物が得られます, 特に、その場所を徹底的に「掃除」するために隙間を埋める必要があるエリアでは.
Hard Rock Mining: A Tough Nut to Crack
砂漠で採掘された金のほとんどはハードロック鉱山で産出されます。, 岩から直接金が抽出される場所.
ほとんどの硬岩採掘作業の初期費用は、ほとんどの探鉱者にとって高すぎますが、, there are still considerable hard rock gold deposits out there that can be mined on a smaller scale.
All you need is a simple rock crusher to break apart the ores for further processing.
Desert Gold Washes Prospecting Tips
Here are some tips for finding gold in desert washes:
- 露出した岩盤や薄い砂利の表土を探します。. This is where gold is most likely to be found.
- Use a gold detector to scan the area. This is a great way to find small nuggets and flakes of gold that you might not be able to see with the naked eye.
- Be patient and persistent. Prospecting for gold can be a slow and tedious process, but it can be very rewarding if you’re successful.
- Start your search in areas that have been previously mined. This is because these areas are more likely to contain gold.
- Look for areas where there has been a lot of water activity. これは、水が土壌を浸食して砂利に金が堆積した地域で金が見つかることが多いためです。.
- 地形に注意してください. 岩盤が露出している場所を探す, 砂利バー, そして河床. これらはすべて、金が見つかる可能性のある場所です.
- 見込み客を探している地域の法律や規制に注意してください. 一部の地域では金の採掘と採掘が制限されています.
