Outstanding High-Grade Copper and Gold Assays from Mountain Home Project, NT

Assays of up to 45% Cu and 11.75g/t Au from rock chips along with stronglyanomalous soil sampling highlight the Project’s significant exploration potential

West Australian-based explorer E79 Gold Mines Limited (ASX: E79) (‘E79 Gold’ or ‘the Company’) is pleased to provide an update on exploration activities at the recently optioned Mountain Home Copper-Gold Project1, located in the Northern Territory.


  • Initial reconnaissance sampling mission highly successful in providing exceptional copper and gold values in selective rock chips and extending the known mineralised structure to 1km in strike extent.
  • Exceptionally high-grade copper assays, including 45.5% Cu, 39.8% Cu and 38.4% Cu, returned from selective rock chip sampling, with seven of the 15 rock chips returning values in excess of 22% Cu.
  • High-grade gold values of up to 11.75 g/t Au in selective rock chips.
  • The mineralised outcrop has been extended by this recent sampling to 1,000m while remaining open along strike to the north and south.
  • Soil samples taken perpendicular to the mineralised outcrop show anomalous copper values, over widths across-strike of up to 80m, with coincident anomalous gold.
  • Further field work planned for the current Quarter.

E79 Gold CEO, Ned Summerhayes, said: “These outstanding rock chip copper and gold results highlight the very exciting discovery potential of the Mountain Home Project. Encouragingly, we have now encountered high grades in both copper and gold along the entire length of the known mineralised outcrop, now extended to in excess of 1km strike extent and remains open to the north and south.

“The soil sampling results suggest there may be parallel structures given the across- strike width of anomalism in both copper and gold. These results give us confidence to both follow-up with programmes to extend the Mountain Home copper system and also to follow up historic positive stream and soil samples elsewhere on the project. We are aiming to undertake these exploration programs within the current September Quarter.”

Northern Territory Project

Mountain Home (EL32470 – NT Minerals Option), EL33886 and EL33886 (both under application – 100% E79)

Assays have been returned from E79 Gold’s initial reconnaissance sampling program at Mountain Home, including high-grade copper and gold values along the length of the prospective and extended 1,000m long outcrop. Results for all recent E79 Gold samples are provided (contained below in Table 1) and standout rock-chip assay results (Figure 1) include:

  • MHR0004 - 28.9% Cu, 0.16 g/t Au
  • MHR0008 - 0.11% Cu, 11.75 g/t Au
  • MHR0009 - 22.0% Cu, 0.45 g/t Au
  • MHR0010 - 45.5% Cu, 0.08 g/t Au
  • MHR0011 - 38.4% Cu, 0.23 g/t Au
  • MHR0012 - 24.9% Cu, 1.33 g/t Au
  • MHR0013 - 39.8% Cu, 1.72 g/t Au
  • MHR0014 – 30.0% Cu, 0.29 g/t Au

It is worth noting that the samples, especially the higher-grade copper results, had abundant oxide-copper mineral malachite (green mineral in Photo 1), that can produce elevated copper results due to supergene (weathering) surficial enrichment. Pure malachite copper content is variable but typically around 57- 58% Cu. Experience has been that the sulphide-rich precursor rocks or sulphide- rich unweathered examples in drilling beneath these types of surface copper assay values will typically be lower grade. For example, 100% un-oxidised chalcopyrite has an average copper content of around 35% Cu – the remainder is iron and sulphur.

Metals Focus: Gold to Average US$3,210 in 2025 as Central Banks Buy and Trade Tensions Grow

Leading gold analysis firm Metals Focus published its annual flagship Gold Focus report on Thursday (June 5).

Throughout the year, the gold price surged at a blistering pace, starting 2024 at around the US$1,980 per ounce mark and reaching a peak of US$2,790 at the end of October. Since then, gold has continued to climb, setting repeated record highs since the start of 2025 — the most recent occurred on May 6, when gold reached US$3,437.

Harvest Gold CEO Outlines Strategic Play in Québec’s Gold-rich Abitibi Region

Harvest Gold (TSXV:HVG) President and CEO Rick Mark believes the company has a strong position in Québec's Abitibi greenstone belt, emphasizing the highly prospective Urban-Barry belt, "a very well-known mine-producing belt."

In an interview with the Investing News Network, Mark also honed in on Québec's supportive mining environment and accessible properties, which keep exploration costs "relatively very inexpensive."

“The exciting thing about the Urban-Barry belt is it contains a (gold) deposit called Windfall, which Gold Fields (NYSE:GFI) just bought from Osisko Mining,” Mark noted. “Now, the interesting thing about that as well is that the belt itself is basically owned by Gold Fields, except for the three large properties that Harvest Gold has in the belt.”
