Since 1886, these areas have produced over 15 million crude ounces of placer gold, mainly from the unglaciated Klondike, west Yukon and Lower Stewart regions. Many areas in Yukon remain unexplored for new placer gold deposits, both in unglaciated and glaciated areas.

If a prospector is interested in a creek, the first step is usually testing for placer gold with a shovel and gold pan. See Where Gold is Found in a Creek or River, which is on the Gold Panning page. When working in a stream channel in BC, the prospector must follow the rules of Hand Panning.

Historically, placer deposits have been responsible for 34% of diamond and 69% of gold production worldwide (Sutherland, 1985), as well as major sources of other minerals, such as platinum group elements (PGEs) and cassiterite (Garnett and Basett, 2005).

The first and most popular for the individual miner is the Placer Claim which allows the owner of the claim to prospect for gold, platinum, silver, etc. in any of the gravels that have had river or water action on them at some point in the past. This includes most any rock that is not attached to the earth.

Placer gold is a term that refers to gold found in a secondary deposit. Usually gold occurs in lode deposits. However, the weathering of the hard rock and action of rivers and even glaciers in some places have carried the fine gold nuggets and particles and deposited them somewhere else away from the original lode deposit.

Placer gold deposits in Canada are usually extracted from streams, creeks and rivers in Canada by amateur prospectors by panning and sluicing. Metal detecting for gold nuggets isn't as common in Canada as it is in Australia and the USA, although some gold hunters have had success with it. Like Alaska, many of the best places for prospectors to find gold in Canada are deep in wilderness areas

A model for the origin of mesothermal lode Au deposits in the Canadian Cordillera invokes deep convection (12-15 km) and chemical evolution of meteoric water in the brittle crust. The fluids ascend in highly permeable zones associated with major strike-slip faults. At approximately 10-km depth, Au-bearing quartz veins are formed.

Paleoplacer deposits such as those of the Witwatersrand consist of stratiform layers (bankets) of auriferous quartz-pebble conglomerate, pebbly quartz arenite and cross-bedded arenite, with gold locally enriched in thin carbonaceous seams. The deposits occur in mature flu- viatile to deltaic facies rocks in extensive cratonic sedimentary basins.

Various hypotheses exist on how gold is formed as it surfaces in numerous types of volcanic and sedimentary rocks. Gold is mainly found in two types of deposits: lode (hard rock veins) and placer (surface). Locating the richest gold bearing areas primarily involves research, planning, dedication and

Some of the largest gold mines in the world are located in Canada. Both placer and lode deposits are mined here, and some exceptionally large gold nuggets and specimens have also been unearthed. Millions of dollars' worth of gold are being mined in Canada every year.
