Latin American Minerals Inc. (TSX VENTURE: LAT) (the "Company") announces it that it has staked three potash projects in the Puna region of northwestern Argentina known for its surface evaporite deposits containing potash, lithium, borax and other minerals. The Company has a 100% interest in approximately 100,000 hectares in the Puna region, which hosts several producing surface potash, lithium and borax mines. The properties occur in an ideal geologic environment for the formation of...

Cassiterite is a tin oxide mineral, SnO2. It is generally opaque, but is translucent in thin crystals. Its luster and multiple crystal faces produce a desirable gem. Cassiterite is the chief ore of tin today. Most sources of cassiterite today are found in alluvial or placer deposits containing the resistant weathered grains. The best source of primary cassiterite is the tin mines of Bolivia, where it is found in hydrothermal veins. Cassiterite is a widespread minor constituent of igneous...

Colemanite (Ca2B6O11·5H2O) is a borate mineral found in evaporite deposits. Colemanite is a secondary mineral that forms when borax is deposited, and then regularly covered with boron containing water. The boron remains after the water evaporates, and the boron and borax eventually form other minerals as for example Colemanite. It was named after William T. Coleman (1824-1893), owner of the mine where it was first found.

Tincalconite is a mineral closely related to borax, and is a secondary mineral that forms if borax is allowed to dry. The crystal shape of borax does not change during the drying process. Its formula is Na2B4O5(OH)4 - 3H2O or Na2B4O7 - 5H2O. While most tincalconite is created by man through exposing borax to dry air, there are natural occurrences of tincalconite, like in Searles Lake, California.

The mineral tourmaline is chemically one of the most complicated silicate minerals. It is a complex silicate of aluminium and boron but because of isomorphous replacement (solid solution) its composition varies widely with iron, magnesium and lithium and other elements entering into the combination to a greater or lesser extent. Tourmaline belongs to the trigonal crystal system and occurs as long, slender to thick prismatic and columnar crystals that are usually triangular in...
