Tips on Crevicing for Gold
November 2012
When everything is still dry, one of my favorite methods of prospecting is using a straw to blow out small cracks and crevices that dot the exposed bedrock along a stream.

Using Google Earth and Other Maps

Last month, one of our readers requested an article regarding the possible use of Google Earth for prospecting research. It was a good idea, so here it is.

Proper Assaying of Placer Samples
November 2012
The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.

Mining, Health Care & Taxes

Like it or not, the US Supreme Court has ruled and the so-called “Affordable Care Act” (ACA) is now the law of the land—and the Tax Code. What’s more, despite the promises of many politicians to repeal it, it may be around in some form for years to come.

Every so often, deadlines are a real pain in the neck! That is truly the case this month as we must complete these musings prior to the Vice Presidential debates as well as the last two Obama-Romney encounters.

World Gold Council News

The World Gold Council reports that gold jewelry demand in the first nine months of 2000 is running a little above the record level of last year. Jewelry demand for the nine months was 2,114 tonnes, 1% above the level of a year ago, according to their quarterly survey “Gold Demand Trends.”

Gold in Kansas and Oklahoma
January 2001
The Great Plains region, contrary to popular opinion, is not entirely flat. There are areas of low hills and badlands, and it is in such areas where gold has been found. The areas of interest range from 700 to 3,000 feet in elevation, with annual precipitation ranging from 15 to 40 inches, in the form of summer thunderstorms and winter snow.

Picks & Pans: An Exciting Hobby
January 2001
The year was 1946, the war was over, and we three brothers were working for Douglas Aircraft, in Santa Monica, California. Jim and I had returned to jobs we held before entering the Navy and George was a “new hire,” having just finished a four-year hitch as a Navy Flight Crewman.

Prospecting for Silver With a Geiger Counter
January 2001
Light-colored volcanic tuff or tuffaceous sandstone often contains small amounts of uranium, enough to be detected with a sensitive radiation detector. Sometimes, the mass effect of the radiation is substantial.

The Furnace Atmosphere During the Fire Assay
January 2001
It has been claimed that the introduction of excess air to the assay furnace during sample fusion can materially increase the gold yield. Testimony by expert witnesses for the defense in recent federal hearings dealing with the dependability of the gold fire assay includes data purported to show this.

The Big Swede was working his pan trying to get rid of the black sand. Usually there were others at the river, but on this day he was there alone. He figured that most of the other fellow miners were either doing their laundry, or working.

Gold in Chihuahua, Mexico
January 2001
Chihuahua, about the size of Oregon, is Mexico’s largest state and one of its most prosperous, with a great influx of foreign capital. The capital city, Chihuahua (pop. 2 million), is 228 miles, by divided highway, south of El Paso, Texas. Topographically, the state can be divided into several provinces, from dry sandy deserts on the north and east, to the forested Sierra Madre Occidental on the west and southwest.
