Astra Exploration samples up to 5.33 ppm AuEq at Pampa

2023-01-25 12:26 ET - News Release

Mr. Brian Miller reports


Astra Exploration Inc. has released exploration updates on its Pampa Paciencia flagship gold and silver asset in the Paleocene belt of northern Chile.


  • Detailed mapping of the Pampa Paciencia project was completed in Q4 2022.
  • Mapping discovered areas of new vein float in the western side of the Impaciencia claims with anomalous gold and silver up to 5.33 grams per tonne (g/t) gold equivalent.
  • 2,000 metres of new interpreted low sulphidation epithermal veins were identified.
  • Two new targets added for follow up with trenching program.

Chief executive officer Brian Miller commented: "The discovery of 2,000 additional metres of vein would nearly double the known vein strike at Pampa Paciencia. The grades continue to demonstrate the potential for a large, mineralized gold and silver deposit. This low-cost, but very effective exploration conducted by our team further demonstrates the exciting potential we believe exists at Pampa Paciencia. It is reasonable to expect that further work like that just completed will identify additional veins in this underexplored district. The company will proceed with a trenching program to better define this gold mineralization ahead of a drill program."

The lithologies at Pampa Paciencia are known to host epithermal and porphyry mineralization yet remain mostly unexplored. The geological information received from the previous two phases of drilling confirmed the need for detailed mapping to further reveal the potential for additional vein-style mineralization. The mapping results demonstrates this potential and was completed by Astra personnel at a 1:5,000-metre scale.

Pampa Paciencia is host to multiple gold and silver bearing low-sulphidation epithermal (LSE) vein subcrops and areas of float material. These subcrops and float materials are in partially covered areas, resulting in the concealed veins only being discovered in 2015.

Mapping has defined two lithological and mineralization domains that are separated by the major Cerro Dominador north-northeast-striking fault. The western domain is characterized by the presence of Cretaceous volcanic rocks, as well as Cretaceous and Paleocene intrusive rocks with LSE vein mineralization and alteration; the eastern domain is characterized by Cretaceous to Paleocene intrusive rocks with porphyry-related hydrothermal alteration.

A total of 2,000 metres of new interpreted vein strike length was added at the Impaciencia Oeste target area, with anomalous precious metals values of up to 3.36 ppm (parts per million) gold equivalent (0.75 ppm Au and 209 ppm Ag) in the north portion of this area.

At Torres, another newly identified target located 1.5 kilometres southeast of Impaciencia Oeste, LSE vein float was identified and accounts for up to 10 per cent of the subcrop and float. The area was sampled with a 100-metre-by-100-metre grid and samples returned up to 5.33 ppm Au equivalent (3.93 ppm Au and 112 ppm Ag). Northwest and northeast structures can be interpreted from the geochemical results at this grid sampling.

The Torres and Impaciencia Oeste areas are interpreted to be part of the same trend, which aligns with the Faride mine LSE veins to the southeast. This trend and, in particular, these two new targets, are ready for a trenching program to define thickness and grade of the veins and to define new drill targets in the Impaciencia claim area.

Cambridge House -- VRIC participation

Astra Exploration will be participating at the Cambridge House -- Vancouver Resource Investment Conference from Jan. 29 to Jan. 30 held in Vancouver, Canada; it will be located at booth No. 508.

About Pampa Paciencia

Pampa Paciencia is a 3,840-hectare, road-accessible, low-sulphidation epithermal gold-silver project located within an active mining district less than 15 kilometres from two major mines (Sierra Gorda and Spence); it is about five kilometres from the Faride LSE mine.

Astra has completed drilling, mapping and sampling, geophysical surveys and localized trenching, at the Pampa Paciencia project, and, in doing so, has defined a vein boulder (float) field over approximately 75 per cent of the project area. The veins do not outcrop as the majority of the project area is covered by a thin layer of gravels and caliche but the vein float can be used to identify areas of high prospectivity.
