Aya Gold & Silver Inc.

Technical Information

Aya has implemented a quality control program to comply with best practices in sampling and analysis of drill core and RC chips. For core drilling, all individual samples represent approximately one metre in length of core, which is halved. Half of the core is kept on site for reference, and its counterpart is sent for preparation and assaying to African Laboratory for Mining and Environment (“Afrilab”) in Marrakech, Morocco. For drilling using RC, all individual samples represent 1.0m in length and a representative portion is kept for every metre in some chip trays stored on site. A split samples representing 1/16th, ranging from 2 to 4 kilogram is sent for preparation and assaying to African Laboratory for Mining and Environment (“Afrilab”) in Marrakech, Morocco.

All samples are analyzed for silver, copper, iron, lead, zinc, tin, and molybdenum using Aqua regia and finished by atomic absorption spectroscopy (“AAS”). Samples grading above 200 g/t Ag are reanalyzed using fire assaying. Gold is assayed by fire assaying. Standards of different grades and blanks were inserted every 20 samples in addition to the standards, blanks and pulp duplicate inserted by Afrilab.
