Astra Exploration moves ground crews to La Manchuria

Mr. Brian Miller reports ASTRA PROVIDES CORPORATE UPDATE, MOBILIZES GROUND CREWS AT LA MANCHURIA PROJECT, ARGENTINA Astra Exploration Inc. has provided a corporate update, including exploration activities at the La Manchuria gold and silver project in Santa Cruz, Argentina. Astra has mobilized ground crews to commence detailed mapping, regional ground magnetics, topographical surveys and sampling ahead of the phase II drill program scheduled to begin in the coming weeks. Astra's chief executive officer, Brian Miller, commented: "Geologists are currently mapping key geological features in preparation for the phase II drill program. The presence of low-temperature vein fragments at surface validates Astra's model that the veins are plunging to the southeast, further indicating the presence of a preserved epithermal system concealed by postmineral volcanics. Detailed mapping also aims to confirm that the andesites are not a continuous basement rock, but rather a series of layers between stratigraphic rock units, the known thickness of which ranges from 10 to 50 metres. Phase I drilling revealed that favourable host rock units exist beneath the andesites and adds additional potential for La Manchuria to host a large, robust high-grade gold-silver epithermal system. The phase II drill campaign is expected to commence in approximately three to four weeks. Winter weather conditions are subsiding, and we are eager to recommence drilling operations as soon as possible."

Astra Exploration is a precious metals exploration company based out of Vancouver, B.C., that is actively building a portfolio of high-quality projects in some of the most important mining jurisdictions in Latin America. The La Manchuria gold-silver project in Santa Cruz, Argentina, over which Astra has an option to acquire 90-per-cent interest, is a high-grade gold and silver low-sulphidation epithermal (LSE) deposit located in the prolific Deseado massif, which hosts multiple world-class LSE precious metals deposits, including Cerro Vanguardia and Cerro Negro, in Santa Cruz, Argentina. The 100-per-cent-owned Pampa Paciencia gold and silver project in northern Chile is located in the Paleocene mineral province in proximity to such major operating mines as Spence and Sierra Gorda. The project shares several important geological similarities to other Paleocene LSE gold-silver deposits, including Faride and El Penon. The 100-per-cent-owned Cerro Bayo project in northern Chile is located in the Maricunga belt approximately 20 kilometres from the Refugio mine. The project hosts a high-sulphidation epithermal (HSE) plus or minus porphyry gold system with similarities to the Salares Norte deposit to the north in the same belt. The Maricunga belt is one of the most endowed regions in the world for gold and copper deposits.
