Press Release Excerpt:
Marigold mine also utilizes Paragon Geochemical Laboratories, a privately held corporation located in Sparks, Nevada. Analytical procedures utilized are ISO/IEC 17025:2017 accredited and ISO 9001:2015 certified. Samples were prepared under strictly controlled processes, and 30-gram aliquots fire assayed with lead collection. The analytical determinations were with aqua regia digestion and Inductively Coupled Plasma analysis (Au-OES30). Results greater than 8 g/t gold were fire assayed with gravimetric finish (Au-GR30). Quality control utilizes layers of embedded controls that are monitored during operations and used for final certification.
All drill samples in respect of the Seabee Gold Operation (“SGO”) underground drilling program and some samples from the surface program were assayed by our onsite non-accredited assay laboratory, which is not independent from SSR Mining. Surface drilling samples not analyzed by our onsite assay laboratory were analyzed at TSL Laboratories Inc. (“TSL”) in Saskatoon, Saskatchewan, which also serves as the QAQC laboratory for our onsite lab. Duplicate check assays were conducted at site as well as at TSL, which is independent from SSR Mining. Results of the spot checks were consistent with those reported. Sampling interval was established by minimum or maximum sampling lengths and geological and/or structural criteria. SGO site lab typically prepares two hundred-gram samples that were pulverized until greater than 80 percent passed through a 150-mesh screen. Thirty-gram pulp samples were then analyzed for gold by fire assay with gravimetric finish (0.01 g/t gold detection limit). TSL prepares a minus150 mesh pulp (95% passing) weighing 250 grams from a minus 10 mesh coarse crush reject. Fire assay with Atomic Absorption finish was completed on a 30-gram aliquot to produce gold analytical results with a 0.005 g/t gold detection limit. Fire assay with gravimetric finish was prepared on those samples with greater than 3 g/t gold.
