Ganoza, CEO. “These assay results reinforce our confidence that higher-grade copper and gold mineralization continues to extend beyond the historical zones. The deposit remains open at depth and along strike, confirming further potential both within and outside the previously defined mineralized shell. Drilling is expected to continue through 2026 and 2027, with the goal of further extending mineralization and increasing the mine life. We also anticipate issuing an updated reserves and resources statement for the El Roble mine by early next year, and remain encouraged by the results to date.”Get the latest headlines, breaking news and columns.By signing up you consent to receive the above newsletter from Postmedia Network Inc.A welcome email is on its way.

The Company began this drill infill program to test the main mineralized body and the immediately adjacent area during the first quarter of 2023 and has continued the program during 2026 with 32 drill holes for a total of 1689.3 meters of drilling.All intervals in Table 1 include only assays of greater than 1% Cu and very high-grade copper or gold sections within these intervals do not occur.Table 1: Exploration Drilling Results with a 1% copper cutoff includeDrill HoleFrom (m)To (m)Interval (m)Cu %Au g/tATDM-11263.8565.61.752.950.27ATDM-11266.769.83.14.70.61ATDM-11273.774.10.44.491.51ATDM-1127676.60.62.410.57ATDM-11287.688.91.35.231.02ATDM-11290.8597.16.257.651.72ATDM-1143031.51.53.140.38ATDM-11564.2564.550.33.980.46ATDM-11568.970.21.31.380.38ATDM-11571.472.416.450.65ATDM-11915.122.27.13.217.63ATDM-12017.621.74.16.1713.4ATDM-1217.913.65.78.487.41ATDM-12114.316.324.335.35ATDM-12571.372.81.54.631.82ATDM-1257479.25.23.750.46ATDM-12579.782.62.912.611.54ATDM-12584.585.91.44.111.63ATDM-1307382.059.056.361.84ATDM-13232.332.80.51.884.97ATDM-13233.235.62.41.816.56ATDM-13665.7715.35.80.36ATDM-13675.2577.72.458.131.29ATDM-13928.829.60.85.580.72ATDM-14016.218.221.182.42ATDM-14025.6529.13.4511.72.55ATDM-14030.4332.66.192.76ATDM-14124.925.150.251.814.33ATDM-14420.622.51.97.180.42ATDM-14426.227.71.54.291.08ATDM-14614.216.225.572.58ATDM-14617.321.84.59.911.95ATDM-14622.424.31.97.42.62ATDM-147131633.544.97ATDM-14716.817.70.95.861.47ATDM-14718.623.14.516.131.44ATDM-14723.725.7214.391.26ATDM-14728.229.51.316.11.08ATDM-14734.135.113.610.45ATDM-14816.116.90.846.4ATDM-14817.624.16.53.779.49ATDM-14824.830.865.842.38ATDM-14836.542.568.381.57ATDM-14978.879.450.657.011.03ATDM-14979.881.824.071.2ATDM-1498485.51.52.882.59ATDM-14993.2595.82.551.260.94ATDM-15015.934.518.67.652.22ATDM-15035.436.20.82.750.34ATDM-15036.941.44.55.691.17ATDM-15120.4210.64.828.4ATDM-151222644.674.35ATDM-15127.936.68.77.581.63ATDM-15246.3470.74.556.58ATDM-15248.849.10.32.721.1ATDM-15449.151.52.41.774.06ATDM-15726.729.953.252.366.94ATDM-15731.05320.954.112.77ATDM-15832.635.52.92.222.16ATDM-15946.448.421.31.27ATDM-15953.858.74.97.954.48ATDM-16153.45540.551.929.83ATDM-1615558.93.94.4416.46ATDM-16174.2578.23.955.474.76ATDM-16181.1853.92.13.28ATDM-16219.5521.351.87.081.54ATDM-16221.7522.350.69.221.61ATDM-16346.6547.91.252.794.9ATDM-164162264.362.02ATDM-16650.351.81.54.620.29ATDM-16659.4622.69.828.22ATDM-17128.537.598.443.58ATDM-171404223.492.06 This advertisement has not loaded yet.This advertisement has not loaded yet, but your article continues below.True widths are dependent on uncertainties in the local strike and dip of the mineralization and are estimated to be between 90% and 95% of the drill intercept.Image 1: Mineralized shells based on historical massive and new bodies at the El Roble Mine with intercepts from the current drill programAtico Mining adheres to strict Quality Assurance and Quality Control protocols. Blanks and certified reference standards are inserted in each sample batch of drill core that is sent to the lab for analyses. Duplicate samples are also inserted into the sample stream. Twelve drill holes are HQ diameter and core samples are split in half using a diamond saw with one half saved for reference and the other half submitted for analysis. Twenty drill holes are NQ diameter core and the entire core was submitted for analysis. The drill hole number with core size and sample status is shown in Table 2. All samples are shipped via secure transport to ALS sample preparation facility in Medellin, Colombia.Analysis is carried out at ALS, Lima, Peru for copper, silver, zinc and lead utilizing 4-acid dissolution followed by ICP-AES, Code OG62. Silver over 100 g is analyzed by fire assay with gravimetric finish (Code GRA22) using WST-SIM. Gold analysis is carried out at ALS Vancouver, Canada. Analysis is by fire assay (50 g) with gravimetric finish (Code GRA22) using WST-SIM.This advertisement has not loaded yet, but your article continues below.The El Roble mine is a higher grade, underground copper and gold mine with nominal processing plant capacity of 1,000 tonnes per day, located in the Department of Choco in Colombia. Its commercial product is a copper-gold concentrate.Since obtaining control of the mine on November 22, 2013, Atico has upgraded the operation from a historical nominal capacity of 400 tonnes per day.El Roble’s reserves estimate, with an effective date of March 12, 2024, includes Proven and Probable mineral reserves of 828 thousand tonnes averaging 2.49% Cu, 2.20 g/t Au and a life of mine until Q1-2027. A full NI 43-101 technical report is available on SEDAR+. For more information on the reserves estimate refer to SEDAR+ and on the Company’s website.Mineralization is open at depth and along strike and the Company plans to further test the limits of the deposit. On the larger land package, the Company has identified a prospective stratigraphic contact between volcanic rocks and black and grey pelagic sediments and cherts that has been traced by Atico geologists for ten kilometers. This contact has been determined to be an important control on VMS mineralization on which Atico has identified numerous target areas prospective for VMS type mineralization occurrence, which is the focus of the current surface drill program at El Roble.This advertisement has not loaded yet, but your article continues below.Garth Graves, P.
