Core Sampling Procedure - The deposit is sampled using diamond drilling, with a total of 1,499 drill holes and 332,603 meters drilled, including 141 diamond drill holes by FireFly totaling 126,877 meters [5] - Core samples are taken in 1-meter intervals, with some smaller samples down to 0.3 meters to accommodate geological contacts [5] - All sample collection and core logging are supervised by a qualified geologist, ensuring industry-standard practices [5][9] Drilling Techniques - FireFly exclusively uses NQ (47.8 mm diameter) diamond drilling, with core orientation performed using a REFLEX ACT III tool [9] - Historical drilling predominantly utilized NQ size, with some BQ (36 mm) for grade control [9][6] Sample Preparation and Quality Control - Samples are dried, crushed, and pulverized, with a ring mill used to achieve 98% passing -150 mesh [5][11] - Quality control measures include the insertion of QA/QC samples at prescribed intervals, with duplicates, blanks, and Certified Reference Materials (CRMs) used to ensure accuracy [15][12] - Historical data was reviewed by independent consultants, confirming that sampling practices meet industry standards [11][22] Assaying and Laboratory Procedures - Assaying is conducted by Eastern Analytical, with 34 elements analyzed using Inductively Coupled Plasma (ICP) and gold assays determined by fire assay [15][12] - The laboratory employs its own quality control measures, including CRMs and duplicates, to maintain accuracy [15][12] Data Verification and Audits - Significant intersections are verified by independent personnel, and no adjustments to assay data have been made by FireFly or Rambler [19][14] - An independent audit in 2018 confirmed that drilling, sampling, and logging procedures met acceptable industry standards [22][19] Sample Security and Chain of Custody - Core is securely stored and transported from the drill site to the core logging facility, with access limited to authorized personnel [21][24] - Regular reviews of sampling techniques are conducted, confirming that they adhere to industry standards [24][22]
