Mining Industry Review 2020

PDAC 2020 Conference 2020 review of the mpst and least favourable jurisdictions

One of the outcomes of the PDAC annual conference is a review of the mining industry for 2020 which includes an assessment of the most and least prospective jurisdictions  to explore and develop resources. This review is undertaken by the Fraser Institute an independent Canadian public policy research and educational organisation with offices in Vancouver, Calgary, Toronto, and Montreal and ties to a global network of think-tanks in 87 countries. In this study the Fraser Institute  indicated that Western Australia is the most attractive global jurisdiction to explore and develop a resource.
world for mining investment followed by Finland (2nd) and the U.S. state of Nevada
(3rd), based according to the Annual Survey of Mining Companies.

Based on 76 jurisdictions  ten most attractive 1) Western Australia 2) Finland 3) Nevada 4) Alaska 5) Portugal 6) South Australia 7) Republic of Ireland 8) Idaho 9) Arizona 10) Sweden

and the 10 least attractive regions are: 67) Nicaragua 68) Mali  69) Democratic Republic of
Congo (DRC) 70) Venezuela 71) Zambia 72) Dominican Republic 73) Guatemala 74) La Rioja, Argentina
75) Chubut, Argentina  76) Tanzania

 

 

 

Geological hazards of our earth

Types of Geological hazards

A geologic hazard  has been defined as an extreme natural events in the crust of the earth that pose a threat to life and property, for example, earthquakes, volcanic eruptions, tsunamis (tidal waves) and landslides.

(OECD Glossary of Statistical Terms – Geologic hazard Definition https://stats.oecd.org › glossary › detail)

Major natural disasters

Using the definition above linking to the crust of the earth, there is a link to the major global natural disasters affecting life and property. Lightning causing death and fire is a natural phenomenon that in extreme situations be generated by large fire fronts.

  • 7 Landslides.
  • 6 Volcanic eruptions.
  • 5 Tornadoes.
  • 4 Lightning.
  • 3 Tsunamis.
  • 2 Hurricanes.
  • 1 Earthquakes.

Of the major natural disasters listed above the effects some can be greatly exacerbated by human activity.  For example landslides and land slips  usually occur when hydrological (water saturation of a rock and soil) loading of the soil and rock mass on steep slopes is excessive.  If these slopes have also been cleared or partially so due to human activities (including agriculture and mining) the landslide can be far more destructive as the rock and soil mass becomes over saturated and will form a sheet like dense flow carrying thick mud and rocks and burying all in its path.  There are numerous examples of this occurring in Latin America. Major landslips can occur im regions that have an unstable substrate such as regions affected by the movement of ice across a landscape that can create clays that can liquefy whne saturated to form a glide plane for large areas of land such as the one in Norway in early June 2020
