First explorer opportunity on a bonanza-grade gold belt discovery at the Mila Target, Motagua Norte
Continuous lines of 2 m long chip channel samples of mixed outcrop and colluvium have returned average grades of 42 g/t gold along a 34 m line, and 54 g/t gold over a 24 m line from two parallel lines 70 m apart in one boulder field at the centre of the target area.
On October 11, 2023, Volcanic Gold Mines and Radius Gold announced the discovery of bonanza -grade gold discovered across wide areas at the Mila target that is part of the Cirilo-1 exploration license at the Motagua Norte project (See news release Oct. 11, 2023).
Highlights of the gold discoveries at the Mila prospect:
- Concentration of bonanza-grade and visible gold in quartz veins over a 250 x 570 m area.
- Continuous line rock chip sampling across mixed outcrop, subcrop, boulder fields of 34 m averaging 42 g/t gold and 24 m averaging 54 g/t gold.
- High-grade gold in both quartz veins and stockwork quartz in the wallrock suggests wide zones of gold mineralisation.
- Visible gold in quartz veins identified in new areas to the south and west of Mila.
- Orogenic gold-silver deposit with significant depth potential.
- Trenching and drilling planned to establish the geometry, width and grade of the gold mineralisation.
After initial prospecting and return of exceptional samples, the company wanted to understand if the very high gold grades (many samples above 1 oz gold / tonne) were the result of selective sampling or widespread across the target zones. In mixed terrain where outcrop, subcrop and float boulders cover wide areas its not possible to be sure of true width. A program of continuous 2 m chip sampling was conducted across this mixed terrain to define the distribution of gold mineralization and target trench and drill priorities.

High-grade gold assays and visible gold occur in both quartz veins, and in wallrock quartz stockwork zones. Multiple quartz veins with at least two different orientations are recognised; north-south and northwest-southeast striking.
The distribution of mineralised boulder float, supported by limited outcrop data, suggests that the high-grade gold mineralisation in the Mila target is concentrated in two north-south structures approximately 200 m apart, each structure at least 250 m strike in length. The current interpretation is that one or both structures support multiple quartz veins across a width of at least 25 to 50 m. Trenching and drilling will be required to look beneath the quartz boulder cover and establish the true geometry, width and grade of the mineralised veins and wallrock stockwork zones in the Mila prospect.

Exploration potential and next step
Visible gold in quartz veins were discovered south and west of Mila prospect in on-going prospecting and rock chip sampling:
- 9.34 g/t and 29.6 g/t gold in two gold quartz veins approximately 500 m south of the Mila prospect.
- Up to 60.2 g/t gold in quartz veins between 800 metres and 1700 metres west of the Mila prospect (along the regional Motagua Norte trend).
The Volcanic team expects further discoveries in the newly discovered Motagua Norte gold belt:
- Very early stage of exploration – geophysics, trenching and drilling pending.
- Orogenic vein and stockwork system in wide, deep-rooted Motagua Shear Zone with significant depth potential.
- Next step: trenching and drilling to establish geometry, width and grade of gold mineralisation. (See news release, Oct. 11, 2023)
