TORONTO, Aug. 19 /CNW/ - Canuc Resources Corporation ("Canuc" or the "Company")TSXV: CDA is pleased to report on the check sampling program conducted on select drill core pulps, rejects and bulk samples. In total, 75 samples were submitted to ACME Analytical Laboratories in Cuenca Ecuador for preparation and shipping to Vancouver British Columbia for final analysis.
Various analyses were conducted on the pulps and rejects from drill hole N10 - 002 and include a repeat of the 30 gram fire assay, a 50 gram fire assay and a screen metallic fire assay, the latter analysis conducted due to the presence of visible gold proximal to the drill collar locations.
Of the 3 analyses conducted, the screen metallic fire assay is of significant interest since this type of analysis is designed to specifically deal with the presence of visible gold in the sample medium.
In order to compare the results from standard fire assay with those obtained from a screened metallic analysis, the reject material for select samples in drill hole N10 - 002 were submitted to ACME Analytical Laboratories and the results are shown below:

Note: * Coarse assay rejects consist of the material that remains after
the laboratory prepares the initial sample for analysis. This material is
generally stored by the laboratory in the event it is required for
subsequent analysis.
In the results above, 9 of 11 samples showed an increase in Au content and taking all samples into account, there was an average increase in Au values of 39%. As a result, the metallic screen process will be utilized going forward. In addition, select samples from the drill program are being selected for re-assay.
In regards to the 30 and 50 gram Fire Assay values, the results utilizing different sample sizes was inconclusive and further work is ongoing.
In addition to the above analysis, 2 small bulk samples (A & B), both weighing approximately 25 Kg, were collected from the Audaces pit in order to check that the splitting of the samples is producing a representative sample. The material was submitted to ACME for crushing (80% through a 10 mesh screen) then returned to CDA for further homogenization. After mixing, the material was coned and quartered with 16 samples from each batch submitted for assay by the screen metallic process.
In bulk sample "A", the results ranged in value from 0.84 g/t gold to 1.37 g/t gold.
Bulk sample "B" was a higher grade sample collected from the pit near the drill collar of holes N10 - 002 and N10 - 004. These results are shown in the table below. With a range in values from 14.94 to 24.37 g/t gold, it is clear that the material contains nugget gold and a proper split of the material could be challenging. The team is in the process of designing a program that will address this issue. This will be done in conjunction with a consulting geochemist.
