Sampling, Analysis and Security of Samples
The core obtained from the Lik deposit during the 2007 and 2008 drilling campaigns was logged on site at the Lik camp. The entire core containing sulphide mineralization was sawn using diamond saws and half of the core was sent for assay. Sulphide mineralization at Lik has a problem in that there is local diagenetic marcasite associated with the margins of the higher grade mineralization and within some of the lower grade mineralization. This material oxidizes rapidly, breaking up the core and rendering samples inappropriate for metallurgical testing. Once core was placed in the sample bags, the air was evacuated and replaced with nitrogen. The samples were sent to Kotzebue by charter and then by licensed carrier to Anchorage. The samples were stored under refrigeration in Anchorage until the end of the drilling campaign. Finally, the
samples were dispatched to G & T Metallurgical Services Ltd. (G & T) of Kamloops, British Columbia. As well as completing metallurgical testing, G & T crushed and analyzed the samples.
The 2008 diamond drill core was not required for metallurgical testing and core was handled normally. Sawn samples were bagged and boxed on site and dispatched to a facility of ALS Laboratory Group (ALS Chemex) located in Fairbanks, Alaska, for sample preparation. The pulps were analyzed at ALS Chemex located in Fairbanks or Elko, Nevada.
