Jasperoide Project

The Jasperoide Project covers approximately 30,000 hectares in a known, world-class copper district in southern Peru.  Jasperoide is located within 50km of Hudbay Minerals’ Constancia and Pampacancha copper/gold mines, MMG’s Las Bambas copper mine, First Quantum Minerals’ Haquira copper development project and Rio Tinto and BHP’s copper exploration projects. 

Jasperoide Map

C3 Metals has identified multiple copper/gold skarn, porphyry and epithermal targets at Jasperoide.  The Company has drilled the first skarn target – Montana de Cobre – and intersected high-grade copper in multiple holes, including 53.2m at 3.11% copper & 0.46 g/t gold, 118.7m at 1.15% copper & 0.37 g/t gold and 229.5m at 0.99% copper & 0.43 g/t gold.  C3 Metals has published a maiden mineral resource estimate on the Montana de Cobre target, as well as undergoing a metallurgical test work program.  The Company has multiple drill permit applications in progress for the areas covering the other copper/gold skarn, porphyry and epithermal targets, including two areas that are currently being mined by local, small-scale miners.

  1. The Mineral Resource estimate has an effective date of 1 May 2023 and the estimate was prepared using the definitions in CIM Definition Standards (10 May 2014).
  2. The CCPS used to calculate the Mineral Resource estimate uses a copper price of $3.75/lb, a copper recovery of 75%, an open pit mining unit cost of $2.35/t, processing costs of $4.66/t and G&A cost of $1.37/t.  The breakeven cut-off grade using these parameters is 0.14% copper.
  3. Mineral Resources are reported in relation to a CCPS in order to demonstrate reasonable prospects for eventual economic extraction, as required by the definition of Mineral Resource in NI 43-101; mineralization lying outside of the pit shell is excluded from the Mineral Resource.  Potential revenue from gold was not considered for the development of the constraining pit shell; the Mineral Resource estimate is not dependent on recovering gold.
  4. The quantity and grade of reported Inferred Mineral Resources in this estimate are uncertain in nature and there has been insufficient exploration to define these Inferred Mineral Resources as Indicated or Measured Mineral Resources.
  5. All figures are rounded to reflect the relative accuracy of the estimate and therefore numbers may not appear to add precisely.
  6. Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.
  7. The Mineral Resource estimate is prepared by IMC of Tucson, AZ, under the direction of Michael G. Hester, FAusIMM, a Qualified Person.

The Measured, Indicated and Inferred Mineral Resources reported herein are contained within a floating cone pit shell to demonstrate “reasonable prospects for eventual economic extraction” to meet the definition of Mineral Resource in NI 43-101.  A NI 43-101 technical report will be filed within 45 days. 

Jasperoide Map


At Jasperoide, high-grade copper-gold skarn in outcrop has been mapped for over three kilometres along strike.  In total, there is 28km of magnetite that runs through the ~30,000 hectare property in a north-south direction with very little drill testing.  The geologic setting at Jasperoide is analogous to the world-class copper-gold deposits at the nearby Las Bambas and Constancia mines: Folded and thrust faulted carbonate sedimentary rocks, a multi-phase intrusive complex, and extensive skarn alteration.  At Jasperoide, copper-gold mineralization is closely associated with magnetite skarn development. The potential for porphyry copper mineralization is demonstrated by phyllic alteration and B-veins proximal to the mineralized skarn.

Surrounded by world-class deposits:

  • Las Bambas  780MT at 0.70% Cu, 170ppm Mo (MMG)
  • Constancia   521MT at 0.31% Cu, 87ppm Mo (HudBay)  
  • Antapaccay   499MT at 0.39% Cu (Glencore)  
  • Haquira   569MT at 0.56% Cu (First Quantum)


Considerable potential for hosting copper at Jasperoide lies within the interpreted “STACKED” skarn system with well-developed mineralogic zonation and near surface oxide copper development, a deeper porphyry-style mineralization and intermediate sulphidation vein overprinting. Given the large volume of skarn mineralization seen at Jasperoide, the potential for a large copper-gold deposit similar in scale to neighbouring mines is possible.

“Jasperoide is located along the well-known, yet surprisingly underexplored Andahuaylas-Yauri Belt in southeastern Peru.  We are well positioned with almost 27,000Ha and multiple skarn, porphyry and epithermal targets.”

Montana de Cobre

Current drilling at Montana de Cobre has outlined oxide copper, gold and silver mineralization covering an area of 650m by 600m to a depth of 250m. This mineralization is characterized by highly oxidized rock with mineralization from surface and includes a high-grade zone near the lower extent of oxidation.
