Mosaic Retraces Seventeen Drill Holes With Pegmatites on Amanda

MONTREAL, Sept. 26, 2023 (GLOBE NEWSWIRE) -- Mosaic Minerals Corporation (CSE: MOC) (“Mosaic” or “The Company”) is pleased to announce that, following a recent compilation of all historical drilling data on the Amanda project, the Company traced the presence of pegmatites in the description of the logs of the seventeen drillings carried out on this project between 1997 and 2010.

Highlights

• 17 historical drillings with pegmatites not analyzed for lithium (GM 55430, GM 56493, GM 60051).
  
  
• 34 pegmatite samples taken by Vanstar Mining Resources in 2020 (2020 Technominex Report - Amanda Project) not analyzed for lithium.
  
  
• 31 pegmatite samples taken by the MRNF in 1998 not analyzed for lithium.
  
  
• Visual presence of spodumene*
  
  
• Presence of indicator minerals such as beryl, tourmaline, muscovite, garnet as well as cesium, tantalum, and rubidium in most samples.
  
  
• Pegmatite swarms in several pegmatite corridors varying from three to seven km in length (on the Amanda project) and widths ranging from a few meters to nearly 30m.
  
  
• Drilling AC-2010-04 located along a corridor revealed 9.8m @ 0.8% Li2O of 212.8m including 5.1m @ 1% Li2O and 1m @ 1.2% Li2O (GM 65074). *
  
  
• Drilling AC-2010-12 on the western edge of the Amanda project intersected a pegmatite with spodumene (not analyzed – GM 65074) *
  
  
• Drilling AC-23-0001A intersected 7m containing 3 to 10% spodumene at a depth of approximately 235 meters. Analyzes pending (See Cygnus Metals press release dated August 29, 2023). *

Almost no analysis was carried out at the time to verify the lithium potential of these pegmatites intersected by drilling. According to certain information obtained, the core samples are still stacked on wooden pallets near the old camp. A team will go to the site as soon as possible to check if it is possible to recover them.

In 2020, Vanstar Mining Resources, following a geological and prospecting survey, counted a swarm of pegmatites forming several favorable NE-SW direction corridors with a length varying from 3 to 7 km. Some of these corridors are located along regional faults. The DEM helicopter survey done by Novatem well defined the areas of high relief that could be associated with the presence of pegmatites (see map below).

Of the 34 pegmatite samples collected by the company, most of these contained beryl, massive tourmaline, muscovite as well as garnet. A few samples also contained spodumene.
