ATERRA Metals (OTCQB: CSSCF) mobilized a diamond drill rig to the Totora Cu/Au Project to continue its Phase I program, planning 1,130 metres of diamond drilling focused on the Totora porphyry and the Frontera deposit.
ATERRA cited historical Frontera resources of 16 Mt indicated @ 0.56% CuEq and 34 Mt inferred @ 0.54% CuEq, plans a new mineral resource estimate in Q3 2026, issued the first tranche of shares to Research Capital, and granted 15.57M stock options at $0.05 exercisable until April 30, 2028.
ATERRA Metals (OTCQB: CSSCF) completed Phase 1 reverse circulation drilling at the Totora Cu/Au Project with 1,575 metres drilled and a diamond drill rig being mobilized within a week.
RC holes encountered water inflow; some holes will be extended by diamond drilling to reach targeted depths. Samples have been shipped for assay with results expected within weeks. Sulphide mineralization and porphyry-style alteration were observed at Totora and Algarrobilla targets.
ATERRA Metals (OTCQB: CSSCF) has started a 3,000 m Phase I drill program at the 1,811-hectare Totora Copper-Gold Project in Chile, focusing on Totora (2,500 m RC) and Frontera (approx. 500 m diamond) porphyries.
The company aims to integrate Phase I assays with historical drilling and publish a resource estimate in Q3 2026. Historical Totora results include 142 m at 0.58% CuEq; Frontera hosts a March 2014 historical resource of 16 Mt indicated at 0.56% CuEq and 34 Mt inferred at 0.54% CuEq. ATERRA cautions historical results are unverified.
ATERRA Metals (OTCQB: CSSCF) executed three option agreements for the Totora copper-gold porphyry properties in Chile's Region III and added the 200-hectare Sevilla concession at no additional cost. The company closed a $2.78 million private placement and plans to mobilize field crews to re-log historic core, run geophysics and target a late Q1 drill program to convert historical results into NI 43-101-compliant resources.

The company is finalizing binding option agreements to acquire three advanced copper-gold porphyry properties in Region III, Chile, ~60 km south of Vallenar.
Key technical highlights include a Frontera historical estimate of 16 Mt indicated @ 0.66% CuEq and 34 Mt inferred @ 0.64% CuEq; other drill intercepts reported at Taruca and Clinton.
Cascada Silver Corp (OTCQB: CSSCF) signed non-binding MOUs to acquire three advanced copper-gold porphyry properties in Chile: Frontera, Clinton and Taruca (Totora cluster), located ~60 km south of Vallenar near HWY 5 and high-voltage power.
Key disclosed facts: Frontera historic resource 16 Mt indicated @ 0.66% CuEq and 34 Mt inferred @ 0.64% CuEq; Clinton historic drilling to >500 m (6,194 m by SQM); Taruca includes Totora (~10,140 m historic drilling) and earn-in terms. Option payment schedules total US$10.0M (Frontera), US$4.0M (Clinton) and US$18.5M (Taruca) over multi-year periods. Cascada has not independently verified historical results.
Cascada Silver Corp (OTCQB: CSSCF / CSE: CSS) provided an update on its project acquisition process and announced the termination of the Mina Guanaca property option agreement on October 7, 2025. Cascada said it completed an extensive review of exploration opportunities across the Andes, focusing on silver and advanced copper-gold projects, and is in active discussions with multiple property owners to build a portfolio of advanced exploration properties. Regarding Mina Guanaca, Cascada reported positive assays in the existing open pit but concluded the potential for economically significant tonnage at depth is limited and therefore terminated the option agreement.
Cascada Silver Corp (CSE: CSS, OTCQB: CSSCF) has announced the completion of Phase II drill assay results from its Angie Copper Molybdenum Property. The drilling program revealed significant molybdenum mineralization, with drill hole DAAS-03 yielding 2,116 ppm molybdenum over 6 metres from 10 metres downhole, within a broader 420-metre interval grading 330 ppm molybdenum.
While a dioritic porphyry complex was discovered in drill hole DAAS-05, the results showed only locally elevated copper grades without significant continuous intervals of copper (+0.15%) or elevated gold assays. The company plans to further examine the molybdenum mineralization and determine if there are additional intrusive phases to the porphyry complex that may be better mineralized.
Cascada maintains an active project generation program and notes an increase in available properties for consideration due to recent changes in Chilean mining concession holding costs during 2025.
Cascada Silver Corp (CSE: CSS) has announced that final assays from its Phase II diamond drilling program at the Angie Copper Molybdenum Project are expected to be released this week. The company completed a 1,641 metre diamond drill program in late February 2025, successfully intersecting a dioritic porphyry complex with variable pyrite and chalcopyrite mineralization in two of three drill holes.
The identified porphyry system, predicted by Phase I drill results which showed significant molybdenum mineralization, is associated with an induced polarization chargeability high coinciding with a magnetic low. The geophysical anomalies suggest an extensive exploration target measuring 1,300 metres by 550 metres.
