Gold Classification: Breaking it Down with Mesh Size

When we talk about gold classification at Bering Sea Paydirt, we’re all about mesh size. It’s like a grading system for the shiny stuff, but let’s make it crystal clear for you, fellow gold seekers. Mesh size refers to the number of openings per linear inch in a screen or classifier. Now that we’ve got that out of the way, we’ll show you how we break it down into easy-to-understand categories. Remember, these aren’t universal definitions, but they work for us.

Flour Gold: The Sands of Fortune

Flour gold, also known as gold dust or fine gold, is like the pixie dust of the gold prospecting world. These minute particles, often no larger than grains of sand, can be elusive and challenging to extract. Much like a dash of seasoning that gives your favorite steak its mouthwatering flavor, flour gold adds a touch of excitement to the gold prospector’s quest.

These ultra-fine particles are comparable in size to a pinch of table salt or a grain of sand. With their minuscule size, they are often found in the most unexpected places, like the cracks and crevices of riverbeds and streams or mixed within the very sand on the beaches of Nome, Alaska. It’s often found in deposits where the water slows down and allows the gold to settle. The swirling currents act like nature’s own centrifuge, depositing the heavier gold particles while sweeping away lighter sediment.

This is the elusive, tiny gold that slips through your fingers like whispers of wealth. It’s anything 30 mesh and smaller, meaning it can pass through a screen with 30 openings per linear inch. It’s the smallest and most challenging to catch, but well worth the effort.

To capture flour gold, you’ll need a steady hand and the right equipment. Gold panning is the most common method, but sluice boxes and spiral concentrators can also help collect this gold dust. Remember, patience and persistence are key when seeking out flour gold, as it’s often the small, unassuming discoveries that accumulate to create a fortune.

Coarse Gold: The Gritty Nuggets of Glory

Coarse gold is like biting into a hearty, satisfying meal, rewarding your persistence and hard work in the field.

Their irregular shapes and textures are a testament to the rugged journey they’ve undergone, shaped by the powerful forces of nature. The weight of coarse gold adds a palpable sense of satisfaction as you hold these treasures in your hand, feeling the heft of their metallic substance.

They’re large enough to be stopped by an 8-mesh screen, but small enough to pass through a 30-mesh one, making them more noticeable than their flour gold counterparts.

It’s often discovered in riverbeds, along the banks of streams, or in ancient channels where rivers once flowed. The presence of coarse gold serves as a tantalizing sign that even larger, more valuable deposits, such as gold nuggets, may be waiting just beneath the surface.

The weight of these gritty nuggets in the palm of your hand are great indicators that there is more gold to be found.

Gold Pickers: The Pebbles of Promise

Imagine yourself panning the waters of a flowing river, the sun glinting off the surface as you patiently pan through sediment. Suddenly, you spot a tiny golden pebble nestled among the gravel in your gold pan. You’ve just discovered a gold picker, the next step up in size and significance from coarse gold.

Gold pickers are like subtle hints of success, offering a tantalizing taste of the riches that may lie ahead. These small nuggets are large enough to be picked up with your fingers or a pair of tweezers, making them an exciting find for both novice and experienced prospectors.

They’re comparable in size to a plump grain of rice or a corn kernel and can be found in various locations. Panning in rivers and streams often leads to the discovery of these treasures, as the flowing water deposits them among the gravel and sediment. Gold pickers can also be found within other placer deposits, nestled in the nooks and crannies where they patiently await discovery.

Pickers are typically between 8 mesh and 1 gram, making them easy to find among the other materials in your pan.

Recovering gold pickers may not require the same level of precision as flour gold, but it still demands a sharp eye and perseverance. A seasoned prospector understands that the presence of gold pickers may hint at larger deposits nearby.

Gold Nuggets: The Crown Jewels of Prospecting

Picture the excitement of standing knee-deep in a river, meticulously panning through sediment, when a brilliant glint catches your eye. As you gently wash away the remaining dirt, a gleaming gold nugget emerges. Gold nuggets are the crown jewels of prospecting. They’re what every gold prospector dreams of finding, next to the motherlode.

Gold Alloys: Unveiling Nature’s Golden Combinations

Gold is a naturally occurring element, often found in its pure form. However, sometimes it can be found combined with other elements, creating gold alloys. These alloys exhibit unique properties and appearances that can pique the interest of prospectors and collectors alike.

Electrum: A Golden Marriage of Gold and Silver

Electrum is a naturally occurring alloy of gold and silver, with trace amounts of other metals such as copper. Its color ranges from pale yellow to greenish-yellow, depending on the proportions of gold and silver present. Historically, electrum has been used for coinage and jewelry, valued for its beauty and durability. This alloy can be found in both placer and hard rock deposits, often in regions where gold and silver deposits coexist.

Gold-Copper Alloys: A Warm-Hued Union

Gold-copper alloys form when gold combines with copper, resulting in a warm, reddish hue. The higher the copper content, the deeper the reddish color. This alloy is known for its durability and resistance to wear, making it popular for use in jewelry and coinage. Gold-copper alloys can be found in various geological settings, including porphyry copper deposits and epithermal gold deposits, where gold and copper mineralization occurs together.
