Notes on the rock samples:

a. Rock samples are grab samples which are by nature selective and not

representative of bulk mineralization. Systematic sampling, such as channel

sampling or drill core is required for representative samples.

b. A chain of custody was used for the samples including security tags.

c. Samples were assayed at MSA Laboratories in Langley, BC, an AC89, IAS

Accreditation Criteria for Testing Laboratories, and has demonstrated compliance

with ISO/IEC Standard 17025:2017.

d. Rock samples were crushed and pulverized to 85% passing 75um, then digested

using aqua regia, and assayed using multi-element ( 39 elements) ICP EM MS,

20g aliquots, Fire assay 30g was used for Au.

e. Internal lab controls and blanks were within acceptable range.

antimony values at Blunt Mountain north side of the property.

The primary target at Blunt Mountain is an intrusive related structure with veins containing

antimony, silver, gold, lead, zinc, and copper, identified over a 3 km strike length. The

mineralization is hosted in a Late Cretaceous aged, Bulkley suite pluton near its

northern edge and partially traverses into the surrounding hornfels, of the Jurassic

Bowser Formation.
