Group 1: Project Overview - The La Union Project spans 2,520 hectares and is characterized as a carbonate replacement deposit (CRD) hosted by Neoproterozoic sedimentary rocks overlying crystalline Paleoproterozoic rocks [5]. - The project features high-grade mineralization with notable grades of 59.4 grams per metric tonne (g/t) gold, 833 g/t silver, 11% zinc, 5.5% lead, and 2.2% copper, indicating significant potential for large gold discoveries [5]. Group 2: Exploration Activities - Surface exploration is ongoing, with the identification of multiple stacked thrust faults in the mineralized area, which may enhance the potential for mineralization [2][3]. - Rock and soil sampling is being conducted, with numerous samples sent for laboratory analysis, and results are expected in the coming weeks [4]. Group 3: Drilling Preparations - A 1,500-meter maiden drill program is set to commence in mid-August 2025, with drilling contractors touring the site and road maintenance underway [2][4]. - The management is focused on prudent financial management of exploration expenditures to de-risk the upcoming drilling program [2].
