Mines Management (MGT-T) Jan 22, '14 served its termination notice to option in a 75-per-cent interest in the property on Jan. 20, 2014. John R. Wilson, president and chief executive officer of Estrella, commented: "Given the historical data and the amount of excellent work performed by Mines Management during its option period, the company is excited to get the La Estrella project back. The mineral system at La Estrella is quite large, and we feel that it has significant upside tonnage potential. Estrella will now actively move ahead on advancing the project, and initially, we will focus on reviewing the data compiled by Mines Management over the past two years."

La Estrella project

La Estrella property is composed of approximately 2,200 hectares of land within the central Peru polymetallic belt and is located 130 kilometres south of Huancayo in the Department of Huancavelica, a region with a history of silver mining dating to the 1500s. The project is in an area of established infrastructure, with roads and electricity, and lies within 30 kilometres of Minera Buenaventura's historical Julcani silver mine, which began operations in 1955.

Exploration of La Estrella

In 2012, eight diamond drill holes totalling approximately 2,700 metres were completed, seven of which intercepted significant thicknesses of gold and silver mineralization (see news release of Sept. 13, 2012). These intercepts expanded the historically known area of mineralization toward greater depths on the west and southwest side of the project's 2012 area of interest.

Because a strong positive correlation between higher-grade gold mineralization and moderate to high values of chargeability had previously been demonstrated on La Estrella project, a 3-D induced polarization/resistivity survey by Val d'Or Geophysics Peru was contracted in December, 2012, to February, 2013, to provide indications of mineralized trends and directions useful for exploration. The survey identified a large, previously unknown area of anomalous chargeability extending north and northwest from the 2012 area of interest for a distance of approximately 1,400 metres. This new area, when combined with previously known areas of anomalous chargeability, forms a prospective zone over 2,000 metres in north-south extent and up to 1,100 metres in east-west extent.

La Estrella geology and mineralization

La Estrella concessions cover a large area of gold-silver mineralization hosted by a thick west-dipping dacite sill beneath a sequence of andesitic volcanic rocks. Gold mineralization occurs as pyrite-associated disseminations in silicified and phylically altered dacite and also as quartz-sulphide stockworks in brecciated or structurally disrupted andesitic rocks. Higher-grade silver intervals (greater than 100 grams per tonne) occur with galena and a variety of sulphosalts in mineralized structures cutting the dacite sill and volcanic package, reflecting an event later than the more widespread gold-silver dacite-hosted mineralization. To date, historical and current sampling and drilling activities have identified a roughly tabular zone of mineralization generally conformable to the dacite sill over 1,500 metres in strike length, 300 to 500 metres in width and 50 to 150 metres thick. Geophysical indications of mineralization include this known area and extend across a strike length of 2,000 metres and width of up to 1,100 metres in the central portion of the deposit. The system remains open to the north, south, west and at depth in the central, widest portion of the anomalous zone.
