Avventura Resources Identifies Gold Anomalies at Horwood Property
Vancouver, British Columbia — March 2, 2026 — Leads & Copy — Avventura Resources Ltd. (CSE:AA) has announced initial results from its shallow soil geochemical survey program on the Horwood Property in northern Ontario.
The survey identified seven discrete anomalous gold zones during a targeting soil sampling program. The highest soil sample contained 210 parts per billion (ppb) gold (Au) in an area without any known gold occurrences. Additionally, a 3-km zone of weak gold anomalism was identified between the Denross and Horwood Lake showings. Grab samples taken 750 m from the historical Denross showing contained gold grades up to 62.0 g/t Au.
The company collected and analyzed 1,361 samples from areas considered most prospective for gold mineralization.
Avventura CEO Sean Flynn said the company is encouraged by the results of the recent shallow soil sampling programs at the Horwood Property. He added that the identification of seven discrete gold-in-soil anomaly areas, and a high-grade grab sample near a historical showing, provides a solid foundation for follow-up exploration and target development.
Flynn also stated that while the property remains at an early stage, these results are helping the company to better define areas of interest and prioritize the next phase of work. Management believes the combination of regional-scale structures and newly identified anomalies supports continued exploration on the property as Avventura advances Horwood through systematic technical programs.
The shallow soil campaign included 1,361 samples over two zones totaling 15.23 sq. km of the 94.6 sq. km Horwood Property. The Horwood Property is located within the northeastern part of the Swayze Greenstone Belt on a northeast-trending fault zone termed the Hardiman Deformation Zone, which is interpreted as a splay fault to the Destor-Porcupine Deformation Zone. The Hardiman Deformation Zone and associated splay faults are important to the formation of gold mineralization in the area, including sixteen (16) gold showings previously reported by the Ontario Mineral Deposit Inventory (MDI). The Horwood Property is underlain by Archean mafic volcanic flows and is cut by a complex suite of intrusive rocks, including gabbroic sills and stocks, the granodioritic Horwood Peninsular Pluton, and numerous small quartz diorite and quartz-porphyry intrusions. Previous exploration work concentrated on outcrop mapping and prospecting, ground geophysics and follow-up drilling (122 drill holes for a 15,545 m).
The survey results were plotted using appropriate ranges to reflect anomalism (< 2 ppb (n = 922), 2-5 ppb (n = 351), 5-9 ppb (59), 9-46 ppb (24), 46-210 ppb (5)). Samples greater than 9 ppb Au are considered highly anomalous in the dataset and typically reflect the presence of gold mineralization in the area. The three highest samples contained greater than 100 ppb Au (104, 182 and 210 ppb Au). The survey identified seven areas of anomalism, with four areas in the northern block and three areas in the south. The anomalous areas were related to later felsic or mafic intrusions cutting the mafic volcanic rocks or small splay faults in the Hardiman Deformation Zone.
Three grab samples collected from outcrops between the historical Denross and Labbe #3 showings contained 0.25, 0.56, and 62.00 g/t Au. The 62.00 g/t Au sample, indicates that high-grades gold mineralization is present on the property. Previous sampling at Denross as part of the NI 43-101 site visited reported grab samples up to 6.01 g/t Au. The 62.00 g/t Au sample is located 750 m from the Denross showing and 300 m from Labbe #3. Two outcrop samples of sulphide-rich metabasalt collected in the south of the property contained background gold concentrations (2 and 10 ppb). Assays for the remaining 173 samples collected in the fall field program are pending and will be reported as soon as the results are returned from the laboratory.
A total of 1,361 shallow soil samples were collected over an area of 94.6 sq. km considered to be the most prospective for gold mineralization at Horwood. The sampling grid was oriented north-south with a line spacing of 200 m and a sample spacing of 100 m. Several tighter grids of 50 m x 50 m spacing were also performed. Additionally, 178 grab samples from outcrops on the property were also collected. Samples were collected following industry best practices under the supervision of Percy Clark, P.Geo. (Clark Exploration Consulting Limited, Thunder Bay, ON) and an appropriate number and type of certified reference materials (standards) and blanks were inserted to ensure an effective QAQC program was carried out. The samples were prepared (dried, sieved, and split) and analysed at AGAT (Thunder Bay) for gold and multi-element analysis. The limit of detection for the gold assay method employed was 1 ppb Au.
