Hecate Lowl<strong>and</strong>s<br />

• lack of scientific knowledge about impacts of commercial harvest on ecosystem<br />

• conflict with timber harvesting<br />

Minerals: Outer Coast<br />

Overview:<br />

The Hecate Lowl<strong>and</strong>s have the highest mineral rating within the plan area. The<br />

geological evolution of the Hecate Lowl<strong>and</strong>s indicates wide spread granite materials,<br />

with skarn deposits showing a prevalence of garnet, graphite, gemstones, magnetite, gold,<br />

copper, silver, zinc <strong>and</strong> molybdenum. Past explorations have identified a potential for<br />

extraction, but the overall specific inventories for the plan area are poor. The high cost of<br />

access to this region has prevented further exploration.<br />

Limestone quarrying has occurred over the past fifty years. Crystallized limestone from<br />

the Hecate Lowl<strong>and</strong>s has been used primarily as a whitener in the pulp process. The<br />

limestone/ marble is crushed. The crushed rock is also used in paint, plastics <strong>and</strong> as<br />

industrial filler. There is a dem<strong>and</strong> for high quality limestone <strong>and</strong> marble cants for the<br />

dimension stone industry.<br />

Granites are the most abundant rock in the area. A variety of colours are evident<br />

including a high quality black granite. Further exploration is needed to determine if this<br />

high quality vein is isolated or if it occurs with greater frequency.<br />

Deposits located close to tide water can be barged with minimal development costs,<br />

making them the most economical area for development. However it is important that<br />

only the highest quality of stone is target in order to cover the high development <strong>and</strong><br />

transportation costs.<br />

The plan area has a wide variety of different types of stone. All of the rock that exists is<br />

quarried elsewhere in the world <strong>and</strong> imported into British Columbia for the use in stone<br />

projects.<br />

Other Mineral Deposits: Outer Coast<br />

Many other opportunities exist within the marine placer environment of plan area but<br />

until prospecting, exploration, research <strong>and</strong> development occur, these opportunities may<br />

not be realized for some time<br />

There is an interest in gas <strong>and</strong> oil exploration within Hecate Strait. Oil exploration has<br />

not occurred for the last 15 years as there has been a moratorium on oil <strong>and</strong> gas. Recently<br />

there has been discussion about lifting it. A portion of Milbanke Sound may be within<br />

the oil exploration area.<br />

Lowl<strong>and</strong>s.<br />
