First assay results for Los Cisnes project

Published by , Assistant Editor
Global Mining Review,

Canada-based exploration and development company New Dimension Resources Ltd. (New Dimension) has completed its Phase I diamond drill programme targeting high-grade silver (-gold) mineralisation at the Los Cisnes project. This is the first drill programme to be undertaken by New Dimension since the acquisition of the Santa Cruz Portfolio of three advanced-stage gold-silver projects from Sandstorm Gold Ltd in May 2018.

New Dimension's CEO, Eric Roth, commented: "I am delighted to be reporting the first assays from our Phase I Santa Cruz Diamond Drill Programme. These initial results have confirmed extensions to the known high-grade silver mineralisation at our Los Cisnes Project, especially in the vicinity of the scout drill hole LCsD-09 completed by Mariana in 2015. Results from our step-back hole LCsD-14 - a 60 m down-dip extension of the LCsD-09 mineralisation - are particularly significant, as it includes a very high-grade interval assaying 0.8 m @ 1653 g/t Ag. No drilling has been completed beneath this level, so potential still exists for extending this high-grade silver mineralisation to >60 m vertically below surface."

Los Cisnes project

High-grade silver(-gold) values were reportedly identified at Los Cisnes from previous channel sampling and scout diamond drilling on the Brio vein/breccia system. Brio is a quartz-sulfide(-Fe-oxide) vein/breccia system which strikes ENE, can be traced on surface for approximately 2.3 km, and is up to 3 m wide. In 2015, 8 scout diamond drill holes for 723 m were completed along the Brio structure, with the best intercept being 2.9 m @ 755 g/t Ag from 32.1 m downhole in LCsD-091. 

Mineralised intercepts at Brio are defined by quartz-Fe-oxide(-pyrite-acanthite or Ag2S)-style mineralisation in a subvertical vein/vein breccia system. A potential N-S cross structure to the main Brio structure (and identified from ground magnetic data) in the LCsD-9 area will also now be reviewed in further detail as this may also represent a significant new target for further exploration at Los Cisnes. Host rocks to the Los Cisnes mineralisation are dominated by an upper sequence of welded ignimbrites and a lower sequence of dominantly lithic ignimbrites.  

Las Calandrias drill update

Drilling has also been completed at the Las Calandrias project, where a total of 25 drill holes for 3708 m were completed. The 2018 drill programme at Las Calandrias focused on extending known high-grade gold mineralisation in the Calandria Norte resource area, in addition to extending high-grade gold mineralisation in the sub-parallel Morena vein/breccia system. Core logging and sampling of the 25 Las Calandrias drill holes are well advanced, with first assays expected to become available during August. 

Ontario-based consulting group AGP Mining Consultants Inc has also been engaged to prepare an updated Mineral Resource Estimate (MRE) for the Las Calandrias project.This MRE will incorporate assay data from both historical and current drilling at Las Calandrias, and is currently scheduled for release in mid-September this year.
