AB - ABSTRACT: El Carmelo chromium deposit, Envigado, Antioquia department, Colombia. Chromite occurs associated with serpentine minerals in an altered peridotite. A study of chemical analyses shows that although the tenor is low, the ore is usable because of the ease of concentration and purification.

AB - ABSTRACT: Pajaritos antimony deposit, Colombia. Investigations were made at several points along the Pajaritos stream to determine the value of a stibnite-bearing vein along a fault plane between two schists. In spite of irregular and low tenor, as well as other exploitation difficulties, the deposit may be workable due to associated gold and silver.
