Dakota Gold Corp. Provides Exploration Update for the Maitland Gold Project

By: Newsfile

Lead, South Dakota--(Newsfile Corp. - May 23, 2023) - Dakota Gold Corp. (NYSE American: DC) ("Dakota Gold" or the "Company") is pleased to provide an exploration update for its Maitland Gold Project ("Maitland Gold" or "Maitland"). Maitland is contiguous with the +40-million-ounce historic Homestake Mine in the Homestake District of South Dakota and hosts overlapping gold mineralization from older Precambrian and younger Tertiary gold events. The Company initiated drill testing for both types of gold deposits in January 2022 and has completed 78,958 feet of drilling and a total of 19 drill holes to date. Earlier this year the Company announced two separate discoveries, the Unionville Zone in Tertiary mineralization (see February 8, 2023, press release) and the JB Gold Zone in Precambrian-aged gold mineralization (see May 4, 2023, press release). Both gold deposits outlined in the two discoveries remain open to depth and in all directions.


  • Significant high-grade gold mineralization has been encountered in two discoveries, the Tertiary Unionville Zone, and the Homestake-Style Precambrian JB Gold Zone.
  • Gold mineralization in both discoveries remain open at depth and in all directions. Similar grade Tertiary gold mineralization occurs in historical drill holes and surface grab samples (best value 9.44 g/t Au) up to 7,300 feet to the north of the Unionville discovery area forming a north-south structural zone of over 10,000 feet long with several parallel structures (i.e., the historical underground Maitland Mine) defining additional untested targets.
  • Precambrian Homestake-style gold mineralization geometries are just now being defined but appear to be increasing in grade and widths to the north.
  • Tertiary and Precambrian-aged structures hosting separate gold mineralizing events lie near each other leading to multiple drill targets and efficiencies in testing both systems. Holes drilled to test for Homestake-style mineralization may also opportunistically test for Tertiary mineralization.
  • The Company currently has 53 drill pads permitted on private land north of the Unionville and JB Gold Zones that will be utilized to test and extend both gold target types.

James M. Berry, Vice President of Exploration for Dakota Gold, said, "Having two large gold systems overlapping in such a small area offers great synergies for exploration, development, and future extraction opportunities. The potential extension of the Tertiary structural system over 7,300 feet to the north from the current discovery area and onto our Blind Gold Project indicates that the current deposit can be significantly expanded. In addition, we believe that the recent discovery of the JB Gold Zone is just the beginning of our goals to identify and define a significant Homestake-style gold ledge in the Maitland area."

Exploration for Precambrian Gold

The Precambrian exploration program at Maitland has been developed with drill holes crosscutting the Homestake stratigraphic sequence within the known structural corridor that extends northward from the Homestake Gold Mine. On May 4, 2023, the Company announced partial results from drill hole MA23C-017 and the significant discovery of the new JB Gold Zone. Drill hole MA23C-017 intersected Precambrian-aged gold mineralization grading 0.204 oz/ton Au over 31.3 feet (7.0 grams/tonne Au over 9.5 meters), including 0.365 oz/ton Au over 15.3 feet (12.51 grams/tonne over 4.7 meters) in the same high-grade quartz-carbonate vein, chlorite-arsenopyrite-pyrrhotite mineralization style as the Homestake Mine.

For Precambrian gold mineralization, Dakota Gold is engaged in the preliminary stages of a systematic approach to exploration for Homestake-style gold deposits, with the current drilling on wide spacing to define the geology, delineate preferential terrains for gold mineralization and to produce discoveries. The next phases of work are geared toward definition of the mineralized zones with drilling on tighter spacing intended to vector exploration toward the centroid of the ledge and the best mineralization. In the near-term, definition drilling will be conducted simultaneously with continued step-out drilling from MA23C-017 northward into ground that is untested by past exploration efforts.

Exploration for Tertiary Gold

Prior to the 1980s, most of the Tertiary-aged gold production from the Homestake District was derived from replacement style mineralization in quartzite and dolomite units of the Deadwood formation that covers the older Precambrian-aged stratigraphy. The Maitland Mine located on the Maitland Gold Project is a past producing mine of the Tertiary replacement type that was shut down due to WWII and never re-opened. The deposit is untested by drilling at the north end and remains open to extension along a north-south trending structure. There is also potential for En echelon replacement mineralization to the west, which is also untested at the northern extents of the mine.

In addition to Tertiary replacement style deposits, Dakota Gold has been exploring for gold mineralization in structurally controlled Tertiary aged breccia zones hosted in the Precambrian stratigraphy. These breccia zones are indicated by mapping, geophysics and shallow historical drilling conducted by Homestake Mining Company, beginning in the 1960s. On February 8, 2023, the Company announced the discovery of the Unionville Zone in drill hole MA22C-009, which intersected 0.104 oz/ton Au over 119.7 feet (3.58 grams/tonne over 36.48 meters) and the April 6, 2023, announcement of drill hole MA22C-007, which intersected 0.210 oz/ton Au over 23 feet (7.19 grams/tonne over 7.0 meters). To date, the Unionville breccia zone has a strike length of approximately 2,700 feet (823 meters) from north to south and is open to extension at both ends and at depth. Complete results from the Company's Tertiary exploration to this date are summarized in Table 1.

Dakota Gold is continuing to infill drill along the trend of the Unionville Zone at the west side of the Maitland Mine (see Figure 1 below). The Company will also begin a process of step out drilling along the structure that appears to control the brecciation that is carrying the Unionville gold mineralization. To the north, Homestake Mining Company's historical drill hole MA93-02 encountered on-trend gold mineralization approximately 3,370 feet north of the MA22C-009, the Unionville Discovery drill hole. Further north, and along the same structural trend lies a zone of Tertiary-aged gold mineralization that was identified by Dakota Territory Resource Corp.'s surface sampling program, previously announced on September 24, 2014. Dakota Territory Resource Corp. is a wholly owned subsidiary of Dakota Gold Corp. and the surface sampling program was conducted by the same technical personnel that are currently working on the Maitland Gold Project. 14 samples were collected from limestone outcrop and the dumps of historical prospect workings east of Tetro Rock that produced gold values up to 0.275 oz/ton (9.44 grams/tonne). Collectively, the 2014 sampling program defined a zone of mineralization (see Figure 1) covering a north-south strike length of approximately 1,670 feet (509 meters).

The on-trend indication of Tertiary-aged gold mineralization north of the Unionville Zone constitutes an extension of the Unionville target of more than 7,300 feet (2,225 meters). Coupled with Dakota Gold's current drilling at Maitland, the overall length of the zone could potentially extend to 10,000 feet (3,048 meters) and is still open at both ends.
