The AIM company and the Alex Stewart Laboratory analysed more than 5,000 samples to confirm that they were accurate and generated in accordance with Western and Russian standards.
The samples were analysed twice, and the difference in metal values between the first and second was “well within” the allowable range.
Amur said the nickel grades were within a 0.5% difference, while for copper, the difference is expected to be 0.7%. As a general industry rule, anything less than 10% is considered acceptable.
More importantly, the results also fall within the more stringent Russian Federation acceptable difference of 5%, which is necessary for the compilation of a TEO – the Russian version of a feasibility study.
A second verification phase – called external control – will now take place which will see SGS Minerals analyse a subset of the samples.
Ensures integrity of information
“We are pleased to update our shareholders regarding the acquisition of the final analytical results and the important Quality Assessment and Quality Control related to this information obtained from our 2018 drill programme,” said chief executive Robin Young.
“We have established that the samples submitted for analysis have been generated in accordance with western industry standards and that the lab can successfully generate consistent results that can be replicated.”
He added: “Using western industry standards and to further establish the quality of the results, we can now move on to a second independent laboratory for obtaining analyses on a subset of the samples analysed by Alex Stewart Laboratories.
“As the second lab will not have access to the results generated by the primary lab, we can independently establish the accuracy of the Alex Stewart Laboratory results.
“This standardised approach has been utilised by Amur since the inception of drilling in 2004 and is in accordance with standard western practice ensuring the integrity of the information used to compile Mineral Resource Estimates.”
