Dunnedin Drills New Copper-Gold Porphyry Discovery in “Gate Zone”: Results Include 102 m of 0.68% CuEq (0.53% Copper & 0.16 g/t Gold) at MPD Project, Southern British Columbia

Dunnedin to Host a Webinar on Friday, January 17th @ 8:00am PST/11:00am EST

December 16, 2019 – Vancouver, British Columbia – Dunnedin Ventures Inc. (the "Company" or “Dunnedin”) (TSX-V: DVI) today  reports results from the Company’s first drill program at its 100% owned MPD copper-gold porphyry project in southern British Columbia.  The MPD project is accessible year-round from paved highways 5A and 97C. 

Highlights Include:

  • Discovery drill hole MPD-19-003 has intersected the new “Gate Zone” containing the highest grade porphyry copper-gold mineralization reported in drill core at the MPD property to-date (figure 1)
  • The new discovery underlies a large copper-in-soil anomaly with over one kilometre of strike at the “Prime” area of the project. Over 100 historical drill holes containing copper and gold mineralization define a large, likely multi-centre porphyry system across 10 square kilometres of the MPD project
  • The Gate Zone includes intervals of higher grade copper-gold within a broad lower grade interval, with mineralization present from near surface to a vertical depth of 800 metres, and remains open at depth
  • Higher grade intervals include:
    • 74.9 metres of 0.54% CuEq (0.43% copper and 0.11 g/t gold) from 297.0 metres to 371.9 metres
    • 102.0 metres of 0.68% CuEq (0.53% copper and 0.16 g/t gold) from 404.9 metres to 507.0 metres
  • Broad moderate grade intervals include:
    • 763.6 metres of 0.28% CuEq (0.21% copper and 0.07 g/t gold) from 52.3 metres to 816.0 metres (entire bedrock drill hole length)
    • 340.7 metres of 0.42% CuEq (0.33% copper and 0.09 g/t gold) from 219.0 metres to 559.7 metres
  • Higher temperature porphyry signatures including bornite and potassic felspar alteration are generally stronger at depth, suggesting an upright and intact porphyry system with copper-gold mineralization potential increasing at depth (figure 2)

Chris Taylor, Chairman of the Board of Dunnedin said, “Our original geological thesis has proven to be correct: We have confirmed significant zones of higher grade copper-gold mineralization at MPD, with mineralization present right from bedrock surface.  This is not a remote project, as the property is located immediately beside the highway, near active copper mines, and is accessible year-round, which significantly lowers exploration costs.”

Claudia Tornquist, President and CEO of Dunnedin said, “With our first drill program at MPD we have drilled the best hole on the property to date and discovered the higher grade Gate Zone where we intercepted 102 metres of 0.68% copper equivalent. This is an impressive intercept, keeping in mind that neighbouring producers mine ore with grades between 0.25-0.30% copper. Drilling at MPD so far has only scratched the surface, and many of the project’s copper-in-soil anomalies remain untested. The large porphyry system at MPD is wide open and we are excited about the great potential for more exploration successes and significant value creation for our shareholders. We will now focus on our exploration plans in 2020 and are defining a large number of drill targets.”

Complete assay results and drill collar/orientation information for holes MPD 19-001, MPD 19-002 and discovery hole MPD 19-003 (Gate Zone) are presented in table 1 and table 2 below.

2019 drilling consisted of a total of 1,766 meters within three holes: two holes at the historic Prime area and one hole at the Man area. The holes drilled at Prime were designed to test the horizontal and vertical continuity of higher grade copper-gold mineralization below approximately 300 metres depth, which was encountered in two historic holes drilled in 2013. Prior to this, most historic drill holes rarely tested below 200 metres. Holes MPD-19-002 and MPD-19-003 were drilled to depths of 646.7 metres and 816.0 metres respectively. Both holes intersected significant copper (plus gold and silver) values over substantial widths and 395 metres apart. Mineralisation occurs in altered porphyritic andesite, diorite and/or monzonite, containing pyrite and chalcopyrite (with associated bornite below 500 metres).  Hole MPD-19-003 is the most successful hole drilled on the MPD property to date and is now referred to as the “Gate Zone”.

Hole MPD-19-001 at the Man Zone also intersected porphyry-style mineralization comprised of pyrite and minor chalcopyrite (+/- bornite). This new drill core from Man will be valuable when evaluating property-scale zonation of the larger porphyry system at MPD. 

The porphyry mineralization drilled at Prime and the new Gate Zone is located on the northeast flank of a broad 600 x 1,100 metre historic copper-in-soil anomaly at surface (see figure 3). The Company now has core from the three known copper porphyry zones on the MPD Project (when combined with historic core from Dillard).

Dunnedin will use core from all three zones to conduct petrographic and geochemical studies. Together with further geophysics, this work will be used to characterize the porphyry system at MPD and define additional prospective areas and targets for a larger drill program in 2020. Dunnedin is fully permitted and has a multi-year, area-based exploration permit for the MPD Project.

QA/QC Procedures

All core samples were sent to ALS Canada Ltd. (ALS) in North Vancouver, BC for preparation and analysis. ALS meets all requirements of International Standards ISO/IEC 17025:2005 and ISO 9001:2015 for analytical procedures. Samples were analyzed using ALS’s Fire Assay Fusion method (Au-AA24) with an AA finish for gold; and by a 33-element four acid digest ICP-AES analysis (ME-ICP61) with additional analysis for Ore Grade Elements (ME-OG62) and Ore Grade Cu (Cu-OG62). In addition to ALS Laboratory quality assurance / quality control (QA/QC) protocols, Dunnedin implements an internal QA/QC program that includes the insertion of sample blanks, duplicates and standards in the field.
