VANCOUVER, BC / ACCESSWIRE / June 2, 2021 / Barksdale Resources Corp. ("Barksdale" or the "Company") (TSXV:BRO) (OTCQX:BRKCF) is pleased to provide details of its planned 2021 technical program at the San Javier copper-gold project in Sonora, Mexico.
- An initial program of 5,000 meters of drilling is planned to begin in July, pending receipt of various approvals.
- Drill testing will begin at the Cerro Verde zone, where previous work has outlined significant near surface oxide copper and gold mineralization up to 200 meters.
- Barksdale's goal is to confirm historic work and test structures believed to control higher grade mineralization.
- Metallurgical test program to better understand the potential processing routes for both copper and gold mineralization.
Rick Trotman, President and CEO of Barksdale stated: "We are very excited to begin testing our initial targets identified by our recent relogging program, which we believe could add significantly to the project in terms of understanding the controls to mineralization and should allow us to update historic resource estimates later this year. With the first holes expected to commence within the next six to eight weeks, this comprehensive program and the results that follow will certainly be an exciting time for Barksdale and its shareholders."
Historic Work at San Javier
The San Javier project hosts multiple zones of copper-gold mineralization interpreted to be associated with an iron oxide-copper-gold (IOCG) style system, hosted within Laramide-age intermediate-to-felsic volcanic rocks. Historic drilling has intersected up to 200-meter-thick intervals of copper mineralization hosted primarily within hydrothermal-tectonic breccias and associated stockworks. Historic drilling demonstrates that the original sulfides, primarily chalcopyrite, have been oxidized to various depths, including up to 200 meters along structures.
Of the three identified zones of mineralization, Cerro Verde is the most advanced exploration stage target at San Javier, with drilling campaigns last active during the 2005 to 2008 timeframe. The last company to actively explore and drill at the project was Constellation Copper Corp. ("Constellation") and its most recent project report was a Preliminary Economic Assessment prepared by International Mining Consultants, Inc. titled "Technical Report on the San Javier Copper Project, Sonora, Mexico" and effective December 20, 2007 ("IMC Report"). The table and data below are taken from the IMC Report, which is available for review under Constellation's profile on SEDAR. Please refer to the IMC Report for further details and all assumptions and qualifications used.
San Javier Historic Resource Estimate above a 0.05% recoverable copper cut-off based on a $2.50 per pound copper price.
|Resources Class||Ore Ktonnes||Total Copper (%)||Contained Cu (Mlbs)|
|Cerro Verde Indicated Mineral Resource||33,500||0.34||254|
|Cerro Verde Inferred Mineral Resource||52,500||0.32||376|
|La Trinidad Inferred Mineral Resource||3,700||0.54||43|
|Total Inferred Mineral Resource||56,200||0.34||419|
Barksdale is not treating these historical estimates at San Javier as current mineral resources as a qualified person on behalf of Barksdale has not done sufficient work to classify such estimates are current mineral resources. Accordingly, such estimates should not be relied upon. However, Barksdale's technical team is currently completing the work necessary to verify or replace the historic estimates at San Javier and believes that such estimates can be used as a guide in determining future exploration drilling. In this regard, the Company is currently undertaking a comprehensive review of available data in order to build an updated geologic model that incorporates key geologic and structural data that appear to control the focus of mineralization at Cerro Verde.
2021 Technical Program
Barksdale has developed an initial 5,000-meter drill program at San Javier, the goal of which is to both increase the geologic confidence and to confirm structural and lithologic mineralization controls, including controls to mineralization at the Cerro Verde zone, which will in-turn guide further drilling. Drill targets for the upcoming program are being generated from our current relogging activities, which are aiding the construction of an updated three-dimensional geologic model.
The Phase I drilling program at Cerro Verde will begin with a single diamond drill rig, utilizing oriented core, focused on i) confirming zones of historically drilled mineralization, ii) determining the orientation of certain structures that appear to be focusing the higher-grade copper and gold mineralization, iii) infilling existing zones of mineralization where drilling data is widely spaced, and iv) refining our understanding of controls and dimensions to mineralization. Results from the Phase I program will then support Barksdale's longer-term plan to generate and drill test targets at other areas within the San Javier concessions. Additionally, multiple large diameter core holes will be drilled to collect material to initiate metallurgical column leach test work.
Recent surface mapping and core re-logging activities have identified an important role for low-angle, west-dipping faults that are interpreted to have formed major conduits for mineralizing fluids. The interpreted intersections of low-angle faults with higher-angle east-dipping faults are a primary target for the initial drilling program. These interpreted intersections have produced some of the higher-grade intersections in historic drilling but have not been adequately tested to show continuity or scale. Additional targets include covered zones where mineralization is believed to have been offset by post-mineral faulting, which remain untested by previous drilling.
To initiate the Phase 1 drilling program at Cerro Verde, Barksdale will need to have completed the federal permitting process and receive approval from the local community which controls the surface rights at the San Javier project.
Barksdale's local subsidiary, Estrella del Cobre S.A. de C.V., has applied to Mexico's environmental authority ("SEMARNAT"), requesting approval to complete surface drilling at San Javier. Based on preliminary estimates, the permitting process should conclude in the coming weeks. The Company is in the process of selecting a drilling contractor so that drilling can be initiated once the environmental approvals are in place. Barksdale is also finalizing a long-term impact benefits agreement with the community of San Javier, which controls the surface rights over the Company's key exploration concessions. This agreement establishes a long-term framework that covers exploration and exploitation.
