Buchans Continues to Intersect High-Grade Mineralisation In Exploration Drilling at Lundberg in Central Newfoundland
Buchans Resources Limited (“Buchans” or the “Company”) announces additional results from its ongoing 7,000 metre drilling program at its base metal exploration projects in the Buchans area of central Newfoundland.
To date, the Company has completed 24 holes (total 3,000 m) at Buchans in 2018, including drilling at the Lundberg deposit itself and at the Oriental East and the Sandfill prospects, both located less than 3 kilometres from the Lundberg deposit. These targets are being explored for additional nearby resources that could potentially be exploited with the proposed Lundberg open pit mine, either as additional development deposits or, potentially, stand-alone mines.
- Drilling on the south-west limit of the Lundberg stockwork sulphide deposit intersected additional remnants of the former Lucky Strike high-grade massive sulphide orebody above Lundberg.
- Hole H-18-3506, intersected 0.10 m assaying 5.53% Cu, 22.50% Pb, 8.50% Zn 83.3 g/t Ag and 0.022 Au below historic underground mine workings.
- The 2018 resource drilling of the Lundeberg deposit has now returned multiple intersections of remnant high-grade massive sulphide ore near historic workings, including 1.0 m 21.99% combined base metals as well as 1.8 m assaying 32.22% combined base metals (July 31, 2018 press release). Buchans is cautiously optimistic that the occurrence of remnants of high-grade Lucky Strike ore above Lundberg may benefit open-pit mine development of the Lundberg deposit.
- Additional delineation drill holes designed to test Lundberg below historic underground workings have been completed and assays are pending.
- Drilling at the undeveloped Sandfill prospect, located 2.5 km northeast of Lundberg, intersected several sections of sulphide debris breccia akin to “transported ores” mined historically in Buchans.
- Hole H-18-3513 intersected mineralization at multiple intervals between depths of 306 and 353 m, including:
7.0 m averaging 0.69% Cu, 1.58% Pb, 5.15% Zn, 33.5 g/t Ag and 0.21 g/t Au (7.4% combined Cu+Pb+Zn %) or (“%CBM”),
including 1.0 m assaying 2.96% Cu, 5.13% Pb, 15.5% Zn, 96.4 g/t Ag and 0.27 g/t Au (23.6% CBM); as well as a lower section of 3.10 m averaging 0.22% Cu, 1.99% Pb, 4.19% Zn, 52.04 g/t Ag and 0.25 g/t Au (6.4% CBM),
including 1.0 m assaying 0.56% Cu, 5.50% Pb 11.40 % Zn, 152.8 g/t Ag and 0.70 g/t Au (17.5% CBM).
- Based on these results from Sandfill, and review of adjacent historic holes, Buchans believes potential exists to identify additional “transported” mineralization within a poorly-tested, interpreted west-southwest trending ore channel. With the location of this mineralization now established by down-hole orientation surveys, Buchans is planning additional holes to explore this trend for additional resources of “transported” breccia-style mineralization comparable to several of the Camp’s historic high-grade mines where Asarco mined 16.2 million tonnes averaging 14.51% Zn, 1.33% Cu, 7.56% Pb, 126 g/t Ag & 1.37 g/t Au from insitu massive sulphide and transported breccia sulphide ores between 1928 and 1984.
- Buchans drilled five shallow holes to the east of the former Oriental mine, located two kilometres east of Lundberg, four of which returned intercepts of near-surface low-grade base metal mineralization including:
Hole 18 -3511 which intersected 3.30 m averaging 0.27% Cu, 0.48% Pb, 2.80% Zn, 7.6 g/t Ag and 0.120 g/t Au (3.55% CBM).
The following table provides a summary of drilling assay results discussed within this News Release. Previous 2018 drilling assays are available in the Company’s News Release dated July 31, 2018.
|Hole||From m||To m||Width m||Cu %||Pb %||Zn %||Ag g/t||Au g/t||*CBM%||Comments|
|H-18-3510||No sig. min. Hole drilled into footwall below overburden.||Oriental East|
* CBM%-combined copper (Cu%) + lead (Pb%) + zinc (Zn%). All holes were drilled from surface as vertical holes except for H-18-3506 drilled at a dip of -45 ° towards true North. True widths are estimated to be 80-100% of reported widths. A map showing hole locations relative to the Lundberg resource is available at www.BuchansResources.com .
Drilling continues at Buchans with approximately 3,000 metres drilled to date in 24 holes with a second drill added to the Buchans project. Additional targets include the West Orebodies and Two-Level deposits near Lundberg, as well as other targets located up to 3.5 km from Lundberg, including the undeveloped Middle Branch prospect, a transported style sulphide prospect located approximately one kilometre further northeast and on trend of the Sandfill prospect.
DRILLING AT DANIELS – UPDATE
Drilling also continues on the Company’s Tulks North property with approximately 1,700 metres drilled to date in 3 holes at the Daniels deposit (assays pending). The Tulks North property is located 20 kilometres south of Buchans, where it hosts two massive sulphide deposits with National Instrument 43-101 compliant resource estimates (see Company’s website for details).
Drilling is being undertaken at both the Daniels and Bobbys deposits to explore for larger accumulations of ore-grade massive sulphides down-plunge of these known deposits. The Company intends to utilize borehole electromagnetic geophysical surveys to complement its exploration efforts as these deposits.
Assays and additional exploration results will be released when received and analysed.
CENTRAL NEWFOUNDLAND ZINC LEAD PROJECTS
In central Newfoundland Buchans is currently undertaking a 7,000-metre drilling program to further delineate and upgrade the Company’s Lundberg deposit, as well as explore several other target areas located less than 3.5 kilometres from Lundberg (Buchans News Release dated May 25, 2018) where the Company is exploring for additional resources that could be exploited in conjunction with the proposed Lundberg open-pit mine.
Buchans has engaged Mercator Geological Services of Dartmouth, Nova Scotia to prepare a new resource estimate expected to be available in Q4 of 2018. The results from the 2018 Lundberg drilling will be compiled with previous drilling results obtained in 2014 and 2015 that extended mineralization beyond the limits of the defined resource estimate compiled in 2013.
In addition, Buchans has engaged AGP Mining Consultants Inc. of Toronto, to conduct an internal scoping study to evaluate and assess possible mining and processing scenarios for development of Lundberg as an open pit mine, including further application of Dense Media Separation (“DMS”) technology. It is expected that the updated resource estimate and scoping study will provide a path forward for completion of a Preliminary Feasibility Study (PEA) on Lundberg as an open-pit, zinc, lead and copper mine.
Paul Moore, M.Sc., P.Geo., (NL), Vice President of Exploration of Buchans, a Qualified Person within the meaning of National Instrument 43-101, has reviewed the technical contents of this release for accuracy.
Buchans Resources maintains and operates under industry standard sampling, assaying and QAQC procedures and protocols. A full description of these procedures can be found within the Company’s News Release dated July 31, 2018.
