To date, Integra has outlined a semi-continuously mineralised area that measures 600m in strike length outside of the current inferred resource boundary, with variable zone thicknesses ranging from 20m to more than 300m.
At Sullivan Gulch, 5,970m were drilled in 13 holes to achieve sufficient drill data spacing to incorporate the newly discovered zone into the new resource. Highlights of drilling at Sullivan Gulch North include 283.4m grading 1.12 grams per tonne.
"We are very pleased with these latest step-out and infill drill results at Sullivan Gulch as they continue to demonstrate significant widths and average grades that are all well above the resource cut-off grade of DeLamar," said president and CEO George Salamis.
The updated resource estimate will provide the foundation for a maiden preliminary economic assessment (PEA) on the DeLamar and Florida Mountain deposits, which is due for completion in September.
Upon completion of the metallurgical drilling at DeLamar, the diamond drill rig is scheduled to mobilise to Florida Mountain, 5km to the east. A minimum of 8,000m of diamond drilling is scheduled to be conducted there over the spring and summer months to explore for shallow oxide and transitional extensions of gold-silver mineralisation.
Metallurgical test-work is ongoing from samples collected from the DeLamar and Florida Mountain deposits to demonstrate amenability of both deposits to a combination of both heap leaching and milling for the PEA.
