Development History

1988: First prototype completed

1992: First patent granted

1993: Independent analyses showed recovery efficiency close to 95% and comparisons with conventional screen deck sluicing showed recovery improvements of up to 40% with 75% less water, setup time reduction from a month to several days and overall costs reduced by 45%.

1998: one Model-100, four large 200-ton and sixteen 5-ton units had been sold to mining operations in Canada, China, Mexico and the USA.

1999-2002: Company focused on use of HPC technology for own mining operations in Canada and commenced development and refinement of Generation-2 Technology

2003: Filed Generation-2 patents and began marketing of HPC Technology in N.America, Germany and South Africa

2004: Official launch of Generation-2 machinery at MinExpo 04 in Las Vegas.

2005-2007: Refinement of Generation-2 technology platform.

2008: Release of updated HPC-10: larger size for higher capacity and more robust construction for 7 X 24 operation.

2009: Introduction of HPC-30.

2010: Introduction of HPC-15.

Note: HPC design feedback and operating experience exceeds 125,000 machine-hours (equivalent to more than 14 years of 24 hour per day, 7 day per week operation).
