Re-release of Orinoco Outstanding Grades of Gold in Tailings
G'Day all -worth a quick review given H.C.- posting content today.
- Five one-tonne random samples of tailings recover a total of 46.37 grams of gold in dore
- • The samples returned an average grade of 9.27 g/t .
Orinoco Gold Limited (ASX: OGX) (Orinoco or the Company) is re-issuing the announcement dated 31 January 2018
titled Orinoco Confirms Outstanding Grades of Gold in Tailings.
This announcement includes further disclosure including a Competent Person sign off and Table
1 required under the JORC code.
Competent Person Statement:
The information in this presentation that relates to Exploration Results is based on information
compiled by Mr Terry Topping who is a member of the Australasian Institute
of Mining and Metallurgy.
Mr Terry Topping is a Director of Orinoco Gold Limited and has sufficient experience,
which is relevant to the style of mineralisation under consideration and to the activity that they are undertaking to qualify as a Competent Person
as defined in the 2012 Edition of the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves.
Mr Terry Topping consents to the inclusion in this report of the matters based on the information in the form and context in which it appears.
It appears OGX went to a lot of trouble so as to ensure transparency & suitable protocol used
including
The milling process is recorded with CCTV and monitored by senior staff to ensure
process integrity & final processing is carried out in the gold recovery room under
rigid security controls and accompanied by the departmental manager inclusive of a competent person as defined in the 2012 Edition of the Australasian Code for Reporting
of Exploration Results, Mineral Resources and Ore Reserves.
Tailings sample testing process description
Sample locations were marked by our geological department at 18 metre centres, coordinates taken,
and excavation depths recorded (Table 1).
Geologists monitored the extraction of the sample to ensure sample integrity.
The one tonne sample was then removed and deposited onto a sterile tarpaulin (Figures 2 & 3).
The material was processed through the 400kg per hour Hammer Mill 2 which is equipped with
two 18kg hammers and sized with 1mm grids.
After passing through the hammer mill the material cascades into a gold trap fitted with a manually controlled compressed air and fresh water supply- the compressed air agitates the material whilst the fresh water supply carries away the floats.
The floats then pass through a sluice box fitted with gold retaining carpets.
After each sample the hammer mill was thoroughly cleaned to prevent contamination of the
next sample.
Heavy concentrates that are contained in the gold trap are then manually panned, whilst the
carpets are folded and cleaned in a controlled environment.
All final processing of the gold concentrate is carried out in the secure gold room.
The milling process is recorded with CCTV and monitored by senior staff to ensure
process integrity.
Final processing is carried out in the gold recovery room under rigid security
controls and accompanied by the departmental manager.
In closing, the initial five one-tonne tailings samples averaging 9.27 g/t gives us some indication
as to how much gold has not been recovered by the gravity plant over the past 18 months
and provides us confidence in the true potential of Cascavel.
