Overview

  • The Rama de Oro project comprises 1940 hectares at the northwestern terminus of the Oaxaca Au-Ag polymetallic volcanic belt.
     
  • A high exploration potential 4 x 2.5 km quartz vein stockwork zone is centered on a northwest-trending structural zone along the eastern margin of the largest known caldera in the Oaxaca volcanic belt.
     
  • The core of stockwork veining includes a 3.5 km long vegetative ‘kill’ zone caused by metals anomalies related to potential mineralization at depth.
     
  • Preliminary rock chip sampling has yielded metal values of up to 80.3 g/t Ag and  and 0.56 g/t Au, with reported higher (unconfirmed) values up to ~1 g/t Au from historical sampling. 
     
  • Polymetallic (Au-Ag-Cu-Mo-Pb-Zn) skarn-porphyry style mineralization lies nearby to the southeast along the same regional structural trend at La Calvera (8km distant) and at a 43-101 compliant resource at Cobre Grande (12km km’s distant).
     
  • The project is accessed by two-lane paved highway from Oaxaca, followed by improved dirt roads from Santiago Matatlán with numerous farm roads providing access to majority of the project area. 
     
  • Oaxaca City, Santiago Matatlán, and San Pablo Villa de Mitla are local sources of skilled workers, water, and power for the project.
     

Geology

The Project is hosted by caldera-related Tertiary volcanic rocks (e.g. El Aguila model) crosscut by hydrothermal veining inferred to be related to late- stage granitic magmatism locally exposed as dikes and underlying the adjacent ‘Nueve Puntos’ mountain. Similar intrusions are associated with a 43-101 inferred resource of 49.8 MT containing 0.5% Cu, 0.04% Mo, 0.22% Zn and 12.9 g/t Ag at the Cobre Grande skarn system, which lies 6km to the East along the same structural trend.  Several rock samples assayed from the project contained anomalous values of gold, silver, arsenic, mercury, and antimony, suggesting that the present-day surface represents high structural levels of a precious metal system.

Technical Report

Megastar has completed a technical report (the “Report”) on the Rama de Oro project prepared in accordance with the requirements of National Instrument 43-101 (“NI 43-101”). The Report recommends a 2-phase exploration program: The first phase consisting of detailed geological mapping, rock- and soil-geochemical sampling, and an induced polarization- resistivity survey to define drill targets.  A second phase, consisting of a 6-hole, 3,600-metre diamond-drilling program.
