General comments

Subject category Comment text
Deposit DEPOSITS FORMED BY MAGMATIC INJECTIONS OF MAGNETITE AND HEMATITE, RELATED TO ACID INTRUSIONS OF THE GRANITE AND DIORITE TYPE. VEIN 1, CONTAINS MOSTLY MAGNETITE; REPORTED TO ASSAY 60% IRON. SOME SILICATE AND PYRITE. VEIN 2 CONTAINS PARALLEL VEINS 500 M NE OF VEIN 1; MASSIVE HEMATITE WITH SOME MAGNETITE. GOOD GRADE. THE LOZAS DEPOSITS (PART OF ACARI CONCESSION?) ARE IN QUEBRADA DE LA LOZA, ABOUT 7 KM WEST OF ACARI, COUNTRY ROCK IS METAMORPHOSED SEDIMENTARY ROCKS AND PORPHYRY NEAR AN INTRUSIVE CONTACT. HEMATITE, IN PART SPECULAR HEMATITE, AND MAGNETITE OCCUR IN LOW-DIPPING FISSURE VEINS OR AS REPLACEMENT OF SANDY BEDS IN THE METASEDIMENTARY ROCKS. THE ORE IS HIGHLY SILICEOUS AND CONTAINS CONSIDERABLE CALCITE.
