Pampa Metals Positioned for Discovery

Key Findings - Block 4

  • Block 4 is the Company's priority project, with characteristics indicative of a large, fertile porphyry coppermolybdenum system, located along the world's preeminent porphyry copper belt in northern Chile;
  • Soil geochemical data is consistent with surface geology, induced polarisation (IP) geophysics, and magnetometry, and other complementary data including 3D modeling and age dating;
  • Anomalous soil geochemical values of Mo, Cu and Au in a heavily supergene leached desert environment, coincide with mapped geology, hydrothermal alteration, and geophysical anomalies;
  • The combination of several geological, geochemical, and geophysical anomalies on the Block 4 property is suggestive of a potential "cluster" of porphyry copper-molybdenum systems, a characteristic typical of some major porphyry copper districts in Chile and worldwide; and
  • The Buenavista Target footprint is ~1.5 km E-W by 1 km N-S along a significant geological structure.

Block 4 / Buenavista - Principal Findings & Conclusions from Technical Data

Preliminary results from a soil geochemical survey were previously reported (see news release dated November 10, 2022), but key findings now include:

  • The soil geochemical data are consistent with key findings identified by surface geology, Induced Polarisation (IP) geophysics, and magnetometry, and other complementary data including 3D modeling.
  • Clearly anomalous values of Mo (up to 14 ppm Mo) and Cu (up to 1,560 ppm Cu) in soils, in a heavily supergene leached desert environment, coincide with mapped hydrothermal alteration at the key central quartz-stockwork zone and the neighbouring quartz-sulphide breccia zone (previously reported).
  • Additional sporadic gold anomalies (up to 175 ppb Au), together with the distributions of copper, molybdenum, and pathfinder elements including Zn, Pb, As, and others, suggest Buenavista represents a fertile Tertiary porphyry copper-molybdenum system located along the world's preeminent porphyry copper belt.
  • Buenavista has a footprint of about 1.5 km E-W by 1 km N-S according to the exploration results to date, and is located on a significant NE-SW trending geological structure revealed by the geochemical dataset and supported by surface mapping.
  • The geochemical data is also suggestive of a further potential target to the SW of Buenavista, and gives encouragement to the likely existence of a further target under cover to the east of Buenavista, currently defined by geophysical data.

Mo in SoilsCompared toBuenavista Magnetic Anomaly

The combination of geological, geochemical, and geophysical anomalies is suggestive of a potential "cluster" of porphyry copper-molybdenum systems on the Block 4 property, an aspect typical of some major porphyry coppermolybdenum districts in Chile and worldwide.

A diamond drilling program to test Buenavista, and likely an additional covered target under cover to the east, is well supported by the various surface datasets, where three to four diamond drill holes totaling around 2,100m have initially been programmed.

Project Summaries and Updates

  • Morros Blancos: The Company's JV partner, Austral, has initiated drill testing of the Rosario del Alto high-sulphidation gold-silver target located in the north of the 7,300-hectare Morros Blancos project (see news release dated January 11, 2022). Five diamond core holes totaling around 2,000m are planned. Highlights to date include:
    • Three prospective areas have been identified within the property boundary along a 15 km x 3 km NE-oriented favorable hydrothermal alteration corridor.
    • Four maar-diatreme structures, a multiplicity of phreatomagmatic breccias extending over an area of ~2 km x 1 km, and a shallow level of preservation of volcanic features together with high-level hydrothermal alteration are identified at the Rosario del Alto target in the north.
    • Systematic surface geochemical sampling revealed a high sulphidation epithermal pathfinder anomaly concentrated on the central zone at Rosario del Alto, with relationships to geological features of interest and demagnetised zones from detailed geophysical surveying.
    • Drilling is focused on the geological, geochemical, and geophysical features of interest.
  • Cerro Blanco: Austral has announced that it has completed geological mapping, geochemical rock sampling, and ground magnetometry at Pampa Metals' Cerro Blanco project (6,500 hectares), which is part of the JV agreement between the Company and Austral (see Austral Q4 2021 Activity Report).
  • Cerro Buenos Aires: Wide-spaced reverse circulation ("RC") drilling completed by the Company in 2021 (see news release dated December 7, 2021) around the porphyry and tourmaline breccia outcrops at Cerro Chiquitin in the north of the 7,400-hectare Cerro Buenos Aires project, resulted in geological, hydrothermal alteration, and geochemical anomalies and zonation patterns indicating a potential porphyry copper target to the southeast of the Cerro Chiquitin outcrops.
    • A detailed pole-dipole IP survey (20 line km total) is currently underway over the post-mineral gravel covered target area to the southeast of Cerro Chiquitin, with results pending.
    • Follow-up diamond drill testing is being considered.
  • Block 4: Detailed geological mapping, combined with high-resolution ground magnetic surveying, discovered an intense quartz-veinlet stockwork hosted within a hydrothermally altered dacitic porphyry intrusion that is spatially coincident with a discrete magnetic high at the Company's 6,800-hectare Block 4 project. The area of interest is approximately 1 km in diameter and is poorly outcropping, being mostly obscured by post-mineral gravel cover (see news releases dated November 2, and October 18, 2021).
    • Six back-hoe excavated trenches totaling 2.3 km were recently completed over the area of interest. 202 field samples (with additional control samples) were collected from 5 trenches, with one of the 6 trenches failing to reach bedrock due to the thickness of gravel cover. Geochemical results are pending.
    • Follow-up IP surveying and/or drill testing are being evaluated pending results from the trenching.
  • Other Projects:
    • Wide-spaced RC drilling on three targets at the 6,600-hectare Redondo-Veronica project in 2021 (see news release dated September 28, 2021) revealed deep porphyry potential at two of the targets, with vectors derived from surface geological mapping, hydrothermal alteration and geochemical anomalies found in drill holes, and deep geophysical anomalies. Follow-up diamond drilling is being contemplated.
    • Geological field work and geophysical surveying at the 10,100-hectare Block 3 project has revealed multiple magnetic features of potential interest in post-mineral covered areas, with geological mapping around the periphery of the covered areas confirming the prospective nature of the area. Further electrical (IP) geophysical surveying is being considered to define possible drill targets.
