[{"type":"text","content":" Toronto, Ontario--(Newsfile Corp. - April 30, 2026) - ATERRA Metals Inc. (CSE: ATC) (OTCQB: CSSCF) (\"ATERRA\") is pleased to report that a diamond drill rig is currently being mobilized onto its Totora Cu/Au Project to continue the Phase I drill program (Table 1). Diamond drilling will focus on the Totora Cu/Au porphyry, where a number of recently drilled reverse circulation (\"RC\") holes, stopped short due to water inflow, will be deepened, and on the Frontera Cu/Au Deposit, where it will be used to confirm historical RC drill results. \"We are quite excited for the start of the diamond drilling and to see core from the Totora porphyry and Frontera deposit,\" said Carl Hansen, CEO of ATERRA. \"While RC drilling is faster and less expensive, core drilling provides a clearer picture of the nature and relationships of the mineralization, alteration and structural controls within the copper-gold porphyries. Understanding the nature of these relationships is useful in the preparation of a new mineral resource estimate and it is our goal to announce a new estimate during the third quarter of 2026.\" Table 1 - Totora Cu/Au Project: Phase I Drill Program Hole ID PorphyryTarget RC Drilling(Completed) Diamond Drilling(Planned) (metres) (metres) ATOR01 Totora 208.0 - ATOR01A Totora 200.0 290.0 ATOR02 Totora 323.3 - ATOR03 Totora 94.0 - ATOR03A Totora 306.0 - ATOR04 Totora 88.0 200.0 ATOR05 Totora 110.0 140.0 ATOR06 Algarrobilla 144.0 - ATOR07 Algarrobilla 102.0 - ATOR08-P Frontera - 500.0 Totals 1,575.3 1,130.0 Frontera Cu/Au Deposit The Frontera Cu/Au Deposit (Figure 1) hosts historic resources (Table 2) of 16 million indicated tonnes grading 0.56% copper equivalent (\"CuEq\") (0.38% copper and 0.22 grams per tonne gold) and 34 million inferred tonnes grading 0.54% CuEq (0.36% copper and 0.22 grams per tonne gold). The resource estimate was prepared by Hot Chili Limited based on 16,175 metres of drilling completed in 2013. All but 2 holes completed by Hot Chili Limited were RC. ATERRA's diamond drilling will provide significant geological information and confirmatory assay data that is required for the preparation of a new mineral resource estimate.
