chemical survey - A measure of the abundance of different elements in rock, soil, water, etc.

Geochemistry - Study of chemical elements in rocks or soil.

Geological mapping – Surveys defining the surface distribution of rock varieties, age relationships and structural features.

Grab sampling - A random sample of mineralized rock with no statistical validity, taken simply to check the type of mineralization.

Grade - The quality of an ore; in effect, the metal content.

Granite – An intrusive rock consisting essentially of feldspar and quartz.

Grid - A network of evenly spaced horizontal and vertical bars or lines, used generally to locate points in the field when placed over a map or chart.

Hanging wall - The rock mass above a fault plane, vein, lode, ore body, or other structure, the underside of the country rock overlying a vein or bed of ore.

Hectare - A square of 100 metres on each side.

Induced polarization survey – A survey to determine the conductivity and chargeability of rock units located along grid lines.

Intrusive - Said of an igneous rock, which invades older rocks.

Li2O – An inorganic chemical compound called Lithium Oxide.

Lime - A white substance, calcium oxide (CaO), obtained by the action of heat on limestone, shells and other materials containing calcium carbonate.

Limestone - Rock consisting mainly of calcium carbonate, often composed of the organic remains of sea animals (mollusks, coral, etc.).

Lode - See vein.

Meta-intrusive - An intrusive rock that has been metamorphosed.

Metamorphosed/Metamorphic - A rock that has been altered by physical and chemical processes including heat, pressure and fluids.

Meta-sediment - A sedimentary rock that has been metamorphosed.

Mineralization - The concentration of metals and their chemical compounds within a body of rock.

Mining lease – A claim or number of claims to which the right to mine is assigned.

Modified grid mineral claim – A claim with north-south and east-west borders, located by using claim posts at each corner and at 500 metre intervals along each side. Each 500-metre x 500-metre interval is referred to as one unit and modified grid claims can total no more than 20 units in size.

Net smelter royalty - A royalty based on the actual metal sale price received less the cost of refining at an off-site refinery.
