Ontario Updates its 136 Year Old Mining Law to Limit Exploration Rights

Amiel Blajchman — Mon, 04 May 2009 00:46:42 +0000

After 136 years, the Ontario government is planning on revising its 136 year old mining law to reflect modern circumstances (including prohibiting exploration on private land in Southern Ontario). Drafted in the 1873 when the exploitation of natural resources was seen as the key to economic success, mining was treated as an activity that superseded anything else. Based on a “free entry” system, a mining company could explore and stake land anywhere in the province, including personal property, aboriginal lands, and some zones of ecological sensitivity.

South Africa is a world leader both in terms of mineral resources and in the development of mining technology to extract these resources. The industry there leads the world in many areas, and has had enormous impact on the growth of Africa and on the environment.

1. The Biggest Open Cast, Hand Dug Mine in the World

The Big Hole of Kimberly was dug by hand, using picks and shovels. There is debate about whether the Big Hole is the biggest hand dug open cast mine in the world. Its surface area of 17 hectares (42 acres) and depth of around 200 metres (650 ft) required the excavation of around 25 million tons of earth and rock. This was achieved in 52 years between 1866 and 1914 by a workforce of up to 50,000 miners. What is beyond dispute though is that The Big Hole yielded 2,720 kilograms (6000 lb) of diamonds significantly more than the Jagersfontein mine, the other contender for the title of biggest. After all what better metric is there than output!

Last week, the Dutch city of Heerlen opened the world’s first geothermal power station that uses water heated in old coalmine shafts. The power station works by pumping water up from 800 meters deep in the mines. At that depth, the water reaches a temperature of 35 C (95 F). It heats 350 homes and is pumped back into the mines after use, where it recirculates two to three times a year.
