Braveheart Resources Inc. ("Braveheart" or, the "Company") is pleased to announce the latest progress on the Bulk Sampling project on its Referendum gold property in southeastern British Columbia.
The Company began the project in 2014 and transported around 250 tonnes of material to Nelson before being shut down for the winter. The material have been crushed and screened to -1/2" and separately stockpiled for processing.
Some issues were experienced with the installation and commissioning of the processing equipment which is generally comprised of a small ball mill and Sepro iCon 350 gravity concentrator. These operational difficulties have been addressed and the plant is now running. Approximately 120 tonnes of the stockpiled material have been processed to date, producing some 150 kg of gold bearing black sand.
The processing operation is currently halted to allow time to assess the results, review the program to date and develop a modified plan moving forward. While further testing and confirmation is required, the stockpile grade appears to be <1 g/t. It is felt that this was caused by excessive dilution in the first excavation activities. In order to overcome this obstacle, a trenching program was initiated on September 22 on the Referendum property to identify additional areas for the balance of the bulk sample (around 750 tonnes). The necessary tonnage will be excavated and transported to the Nelson plant during the month of October;
Some preliminary results from the processing operations are as follows:
- A 1.5 kg black sand sample assayed 129.5 g/t Au;
- A 4.2 kg black sand sample underwent flotation testing with excellent results including:
- Overall concentrate grade: 4,452 g/t Au
- Head grade: 146.2 g/t Au
- Fine Au fraction (-500 μm) recovery: 99.6%
- Overall Au recovery: 83.3 %. It is projected that if the +500 μm fraction (grading 57.1 g/t Au) had been floated, overall recovery would be >90%.
In addition to the Referendum activities, a large (around 100 kg) grab sample from Whitewater was recently subjected to a crushing/milling/shaker table test at a facility in Bellingham, Washington. This testing produced 4.86 kg of concentrates that assayed 819.6 g/t Au.
All assaying has been performed by Met-Solve Analytical Services and the flotation testing by Met-Solve Laboratories, both companies are located in Langley, BC. Based on these encouraging results, Braveheart is investigating the purchase of a flotation cell to optimize overall gold recovery and permit small-scale smelting;
Braveheart is encouraged with the overall program to date. The main objective of a bulk sample is to obtain technical information on a deposit, particularly mining and physical characteristics and it is felt that significant knowledge has been gained. The Company will be submitting applications for additional bulk sampling on both the Referendum and Whitewater properties for 2016.
