Recent drilling success has warranted the bulk sampling plan at Golden Crown. The proposed bulk sampling will involve processing up to a total of ~8,000 tonnes of high-grade ore using a 30 tonne excavator or an equivalent machine capable of a 7 – 8 metre digging reach. This process will verify gold grades and assess mining feasibility.

Bulk Sampling. The first step in assaying is to obtain a sample, and it is all important that the portion selected should be representative of the entire quantity (Fig. 1). No special pieces should be picked from the bulk, but the desired quantity is taken indiscriminately from the entire original parcel. Crushing

Bulk samples tend to be smaller (from a few tonnes to 250 t), more numerous samples from single locations or grouped together from underground development (e.g., 30,000 t at Nalunaq, Greenland ) or surface trenches. In relatively rare cases, bulk sampling may be the only way to evaluate gold grade. In some cases, a bulk composite of 1 t or more ...

Another important method recently came into practice is bulk leach extractable gold (BLEG). Significant change in this method is use of the bulk sample instead of a particular size fraction and leaching of gold (irrespective of size) with cyanide solution. It does not involve any sample processing. Data becomes more reliable and reproducible.
