HECLA HAS A SMALL FOOTPRINT

Small geographic, environmental & safety risk footprint

Less than 3,900 acres = less than one large

open pit mine in Nevada

  • GHG emissions = 9,500 cars (280M cars in the U.S)
  • We produce nearly 3X more silver equivalent ounces per ton of GHG emissions as our peers
• Low water use
• • Use less water per ounce produced (63 gallons) than a typical person does per day (100 gallons)
• Safe industry, safer company

MINING INDUSTRY IS A SAFE INDUSTRY

Industry's safety issues of the past create an inaccurate perception

• Least fatalities of 10 major industry categories in last 10 years
  • Construction- most workplace deaths
• • Government- most nonfatal injuries and illnesses - days away from work
  • Agriculture, forestry, fishing and hunting- highest death rate
  • Transportation- highest injury and illness - days away from work rate
