The Santa Cecilia project is located approximately 100 km east of the city of Copiapo, Chile, in the southern region of the world-class Maricunga belt and immediately north of the El Indio belt. The belt is characterized by gold epithermal and gold – copper porphyry deposits that are Oligocene - Miocene in age, including world-class multi-million-ounce deposits such as Salares Norte, La Coipa, Cerro Maricunga, Marte, Lobo, La Pepa, El Volcan, Caspiche and Cerro Casale.
The 3,250-hectare Santa Cecilia property is immediately adjacent to the Norte Abierto project, held by Newmont and Barrick, which is comprised of the Caspiche and Cerro Casale gold – copper porphyry deposits. Norte Abierto is the fourth largest undeveloped gold project, globally¹.
Torq 2024 Drill Results:
Torq’s phase II of drilling resulted in an intercept of 0.36 g/t gold and 0.078% copper over 502 m from 98 m down hole, including a higher-grade interval of 0.69 g/t Au and 0.10% Cu over 20 m from 354 m down hole at the Pircas Norte target. See April 18, 2024 news release for further details.
Torq 2023 Drill Results:
In the Company’s inaugural drill program at Santa Cecilia, it’s second hole intersected 557 m of 0.38 g/t gold, 0.23% copper and 56 ppm molybdenum at a depth of 442 m – 999 m within wall rock at the Cerro del Medio target, demonstrating a substantial increase in grade from historical drilling. The increased grade demonstrates a clear vector to the south and the east toward a potentially higher-grade causative intrusion. See August 2, 2023 news release for the results.
Limited Historical Exploration:
In 1988 – 1990 a major international mining company (“previous operator”) drilled 47 holes, totaling approximately 14,000 metres (m), and completed 1,200 m of exploration tunnel development that clearly defined epithermal gold and gold – silver mineralization as well as gold – copper porphyry mineralization at surface and shallow depths, respectively. A subsequent operator of Santa Cecilia then drilled two deeper holes in 2012 that successfully encountered gold – copper – molybdenum porphyry mineralization underlying the shallow mineralization defined by the previous operator’s drilling. An intercept of 925.7 m of 0.21 g/t gold, 0.27% copper and 82 ppm molybdenum was encountered at the Cerro del Medio target. Following the two-hole drill program, the operator conducted ground-based Quantec Orion 3D induced polarization and magneto – telluric surveys to further define porphyry and epithermal targets across the property, the majority of which remain untested.

In September 2022, the Company signed a seven-year social access agreement that covers the length of the underlying option agreement for 100% ownership and allows for drilling and other exploration activities. Following this, in December 2022 Torq initiated a surface work program to define drill targets, which included: geochemical soil survey (1,880 samples) and rock sampling (1,224 samples), surface mapping, geological and alteration mapping and integration of data sets. In March 2023, the Company also commenced its inaugural drill program at the project. The Company drilled two holes at the Cerro del Medio target and intercepted higher-grade, closer to surface than what was drilled historically, including an intercept in its second drill hole of 557 m of 0.38 g/t gold, 0.23% copper and 56 ppm molybdenum at a depth of 442 m – 999 m within wall rock. Approximately 700 m northeast, Torq’s first drill hole on the project is intercepted 476.3 m of 0.23 g/t Au, 0.22% Cu and 93 ppm Mo at a depth of 584 m – 1,060.3 m. Both drill holes bottomed in mineralization and were drilled into wall rock, indicating the higher-grade causative intrusion has not yet been found at this early stage of exploration. Read the news release here: August 2, 2023 news release.
On July 19, 2023, the Company released rock sample results from the eastern region of the Santa Cecilia project, which demonstrate that three porphyry targets adjacent to the Caspiche deposit are mineralized on surface. The rock sample results positively corroborates the soil geochemistry targets from both the Pircas Norte and Gemelos Norte target areas and these areas will be prioritized for the next phase of drilling, anticipated to begin in Q4 2023. Read the news release here: July 19, 2023 news release.
On May 3, 2023, the Company announced it had identified seven porphyry targets, including Cerro del Medio where Torq’s first two drill holes in to the project are located. The Company’s technical team believes each target area has the potential for a major porphyry discovery. Read the news release here: May 3, 2023 news release.
In early 2024, the Company initiated phase II of drilling at the project. The program consisted of approximately 1,500 m over three diamond drill holes; two located at the Pircas Norte target and one at the Gemelos Norte target. Drill hole 24SC-DDH-003 intercepted 0.36 g/t gold and 0.078% copper over 502 m from 98 m down hole, including a higher-grade interval of 0.69 g/t Au and 0.10% Cu over 20 m from 354 m down hole at Pircas Norte (Table 1). The drill hole ended in mineralized intrusive diorite breccia due to logistical limitations and the reported intercept remains open. These results represent a new discovery of significant gold-copper porphyry mineralization and confirm the Company’s exploration thesis for the broader Santa Cecilia project.

Near Surface Mineralization – Cerro del Medio Target:
The surface mapping, soil sampling, rock sampling and 14,000 m drill program completed by the previous operator were primarily across the Cerro del Medio target area of the project and focused on identifying shallow epithermal mineralization. Select highlights from the previous operator’s drilling include 34 m of 1.09 g/t Au & 0.14% Cu, 22 m of 1.01 g/t Au, 162 m of 0.36 g/t Au & 0.14% Cu, 132 m of 0.44 g/t Au & 0.06% Cu and 256 m of 0.37 g/t Au & 0.04% Cu. The image to the right illustrates a representative three-dimensional view of the mineralization drilled by the previous operator. Additional results from that drill program are presented below in Table 1. Torq’s technical team considers these results to be significant as they demonstrate the need for further drilling to potentially define a mineralized body at shallow depths. The mineralization encountered in the drill holes is primarily oxide gold and gold – copper mineralization from surface to depths of approximately 250 m. This near surface mineralization is primarily characterized by extensive zones of silica stockwork veining associated with hematite and jarosite as well as minor silica – pyrite veins.

The Vetas Condor high-grade gold – silver epithermal mineralization is encountered on the western flanks of the Cerro del Medio target area where east-west trending quartz – alunite structures are exposed over a 1 km by 350 m area. The previous operator completed a total of 1,100 m of horizontal exploration tunnels that were oriented sub-parallel to parallel to the quartz-alunite ledges. Evidently, crosscuts oriented perpendicular to the structures were not completed and therefore true width of the high-grade mineralization was not determined.
The initial 200 m of the tunnel are oriented sub-parallel at a 20-degree angle to the mapped quartz – alunite structures. Highlighted intercepts from this section of the tunnel, while not true width, demonstrate the high-grade potential of the structures, and include 2.38 g/t gold and 101 g/t silver over 32 m and 0.66 g/t gold and 13.5 g/t silver over 134 m. In addition, approximately 436 m into the tunnel, a high-grade vein sampled 58 g/t gold and 27 g/t silver over 2 m. Table 2 below summarizes the significant intercepts in the exploration tunnel.

Torq’s technical team believes that the high-grade mineralization encountered in the tunnel has not been adequately tested. There have only been three shallow drill holes testing the veins encountered in the first 200 m of the exploration tunnel, which included 6.82 g/t gold and 16.8 g/t silver over 20 m at a depth starting at 110 m (true width unknown). Table 3 below summarizes drill results from the three drill holes that tested below the tunnel. Torq plans to aggressively explore for high-grade gold – silver mineralization along the 1 km long corridor defined by quartz - alunite structures.

Underlying Porphyry Mineralization – Cerro Del Medio Target:
A two-hole drill program to test for porphyry mineralization beneath the epithermal mineralization encountered in the previous operator’s drilling was conducted from January 2012 to May 2012. The two holes were drilled from the northern side of the topographic high, defining the Cerro del Medio target area, and both intersected hundreds of metres of gold – copper – molybdenum porphyry-style mineralization. Drill hole CDM 03 intersected 925.7 m of 0.21 g/t gold, 0.27% copper and 82 ppm molybdenum, beneath the drilled gold mineralization from surface of 1.38 g/t gold over 24 m (drill hole SP-SC-24) by the previous operator in 1989. This demonstrates the potential for mineralization over one vertical kilometre from surface that remains open at depth and laterally. Table 4 below lists the intercepts from both drill holes.
Table 4: Cerro Del Medio Target - Underlying Porphyry Drill Results (January 2012 - May 2012)
Hole ID | From (m) | To (m) | Length (m) | Au (g/t) | Cu (%) | Mo (ppm) |
CDM-12-002 | 870 | 1,738.8 | 868.8 | 0.09 | 0.20 | 156 |

Subsequent to the successful drill program testing for porphyry mineralization, ground-based Quantec Orion-3D induced polarization (IP) and magneto-telluric surveys were conducted in November - December of 2012 to characterize the geophysical signature of the underlying porphyry mineralization. The encountered porphyry mineralization was characterized by very low resistivity values, measuring between 3 – 6 ohm m, moderate chargeability values of less than 30 mrad and zones of very low magnetic susceptibility. Critically, the survey shows an area of 2 km x 2 km x 1 km of low resistivity values, which further demonstrates the potential to greatly expand the porphyry mineralization encountered. Torq plans to further explore the porphyry system by targeting structural corridors and potential feeder structures defined through the geophysical surveys.
High Priority Target Areas – Las Pircas – Pircas Norte:
To the east of the Cerro del Medio area, where the majority of the historical exploration work has been conducted, are the Las Pircas and Pircas Norte target areas. These targets are located approximately 2 – 3 km from the Caspiche deposit and are defined by areas of strong epithermal silicification alteration, which Torq’s technical team believes have significant potential for the discovery of underlying porphyry mineralization. This is supported by the low resistivity and moderate chargeability geophysical signatures, which start at depths as shallow as 250 m beneath the surface, as defined in the 2012 ground-based Quantec IP and magneto-telluric surveys. Both targets are characterized by resistivity lows of between 3 – 10 ohm m and moderate chargeability values of 30 – 40 mrad, which are consistent with the geophysical responses associated with porphyry mineralization under the Cerro del Medio target area. Together, these anomalies are approximately 1 km by 500 m, as defined by the resistivity data, but remain open at depth. Historical soils show a gold – silver – copper – molybdenum anomaly over the target areas coincident with the geophysical anomalies. The Las Pircas target area has only five shallow historical drill holes, totaling 476 m, that did not intersect the geophysical anomalies, leaving the target untested. The Pircas Norte target is under cover and has never been drill tested. Three rock grab samples taken from a small, isolated outcrop within the target reported a best result of 1.4 g/t gold and 0.5% copper associated with stockwork veining from a diorite porphyry exhibiting chlorite alteration after secondary biotite. Torq plans to aggressively explore the Las Pircas and Pircas Norte target areas with surficial programs to rapidly advance them to drill stage.

Notes on Historical Exploration Information
In the course of optioning the Santa Cecilia property, the Company’s geological staff was provided with a number of technical reports by past operators dating variously from 1985 to 2015. All drill results and material data sets have been included in this news release. These reports summarized and assessed certain geological, geochemical and geophysical work carried out by the past operators. Also included in the information package provided were reports on drilling in 1988, 1989, 1990, and 2012, including assays. None of the reports attempted to establish any resource on the property. The Company’s geological staff has now digitized much of the underlying data and is using the reformatted information to assess the conclusions of the earlier work and to plan future work. Drill core from the 2012 drill program is still available for re-assay. The prior work will be summarized and evaluated in an NI 43-101 compliant report. Until such summary and assessment are described in an NI 43-101 report, readers of this news release should appreciate that the posited geological modelling is based on information which, while compiled by reputable operators, has not yet been systematically verified and evaluated for accuracy and completeness.
2012 CDM Drilling
Historical drill samples were taken by sawing drill core into equal halves on site with one half being sent to Acme Analytical Laboratories in Copiapo, Chile for preparation and analysis. All samples were assayed using 30 g nominal weight fire assay with AAS finish (Acme method G6) for gold. Silver and base metals were analyzed as part of the multi-element aqua regia digest ICP-ES method (1D01). QA/QC programs for 2012 core samples using lab duplicates, standards and blanks indicate good accuracy and precision in a large majority of standards assayed.
Soil Sampling
Approximately 1-3 kg of soil material was collected on a 100 m x 100 m grid and sent to ALS Lab in Copiapó, Chile or La Serena, Chile for preparation and then to Santiago, Chile and Lima, Peru for analysis. All samples are assayed using 30 g nominal weight fire assay with AAS finish (Au-AA23) and multi-element super trace four acid digest ICP-AES/ICP-MS method (ME-MS61L). QA/QC programs for 2022-2023 soil samples using internal standard samples and duplicates, lab duplicates, standards and blanks indicate good accuracy and precision in a large majority of standards assayed.
Rock Sampling
Approximately 2-4 kg of material was collected for analysis and sent to ALS Lab in Copiapó, Chile or La Serena, Chile for preparation and then to Santiago, Chile and Lima, Peru for analysis. All samples are assayed using 30 g nominal weight fire assay with AAS finish (Au-AA23) and multi-element using four acid digest ICP-AES/ICP-MS method (ME-MS61). Where Au-AA23 results were greater than 10 ppm Au the assay were repeated with 30 g nominal weight fire assay with gravimetric finish (Au-GRA21). Where MS61 results were greater or near 10,000 ppm Cu the assay were repeated with ore grade four acid digest method (Cu-OG62). QA/QC programs for 2022-23 rock samples using internal standard samples and duplicates, lab duplicates, standards and blanks indicate good accuracy and precision in a large majority of standards assayed.
Drilling 2023
Analytical samples were taken by sawing HQ or NQ diameter core into equal halves on site and sent one of the halves to ALS Lab in Copiapó, Chile or La Serena, Chile for preparation and then to Santiago, Chile and Lima, Peru for analysis. All samples are assayed using 30 g nominal weight fire assay with AAS finish (Au-AA23) and multi-element using four acid digest ICP-AES/ICP-MS method (ME-MS61). QA/QC programs for 2023 core samples using internal standard samples and duplicates, lab duplicates, standards and blanks indicate good accuracy and precision in a large majority of standards assayed.
