Since the British Gold Standard was established in 1717, the price of gold generally has been fixed officially, and thus it has tended to remain stable. The U.S. Congress in 1792 adopted a gold standard of $19.39 per troy ounce, which lasted to 1834 when the official price was set at $20.67.
gold-silver bead was obtained by the standard fire assay method. This bead was dissolved in acid and the gold was determined quantitatively by atomic-absorp tion spectrometry (Huffman and others, 1967). The limit of detection is 0.02 part per million (ppm) gold for samples of 10-15 grams and is slightlyhigher for smaller samples.

· The property is located in a part of the Yukon where very little placer activity has taken place. We had a small team of three guys and a lot of equipment. The Yukon, like BC and Alaska, was explored and settled by prospectors in the late 1800s. The Klondike gold rush of 1896-1899 was the largest and most storied gold rush in history.

Gold has a high unit value, so that the amounts of gold in a cubic metre of gravel that is economic may be as low as 1 part per one hundred million. Gold distributions are often extremely erratic. The combination of these problems results in a situation where the sampling of placer gold …
To be honest, when it comes to placer exploration, every ancient channel in a gold-bearing area is worth exploring, regardless of the age. A channel that only formed 100 years ago has the same likelihood of containing placer gold as one that formed 3 million years ago during the tertiary period.

· Prospecting for placer gold, except perhaps in the case of buried placers, is the simplest form of prospecting. Gold, platinum, and tin are the principal metallic minerals won from placers, but gold (alloyed with varying percentages of silver) is the only metal that has been recovered in commercially important quantities from placers in the United States.
