The Luna Roja gold skarn project is located in Nicaragua’s North Caribbean Coast Autonomous region, close to the historic mining town of Rosita and 26km to the southeast of Bonanza and the gold mining operations of Royal Road’s 50-50 strategic partner in Nicaragua, Hemco Mineros Nicaragua.
Luna Roja is located within Nicaragua’s “Golden Triangle”, a well-known historic mining region located in north-eastern Nicaragua. The area is host to three historic mines, Santa Rita – Rosita (Skarn Cu-Au), La Luz – Siuna (Skarn Au-Cu) and Bonanza (Low Sulfidation Epithermal). Since 1900 the district has produced in excess of 8 million ounces of gold and 12 million ounces of silver from mainly epithermal vein systems, and skarns.
Rocks within the La Luna project area are predominantly Cretaceous age limestones and shallow marine sedimentary rocks that have been intruded by Upper Cretaceous to Tertiary age dioritic intrusions and hydrothermal breccia-bodies. Cretaceous age sedimentary rocks have been folded at-least twice.
Gold occurs with skarn-type mineralization represented primarily by pyroxene-diopside-wollastonite and sulphides. Gold is most commonly related to elevated tungsten in skarn-type rocks.
Royal Road and Hemco have completed an initial 17-hole, 2472 meter, scout drilling program at Luna Roja. This is the first drilling program to be completed on the project. Significant intersections include:
LR-DDH-003 49m at 2.8 g/t gold (including 22m at 5.3 g/t gold)
LR-DDH-005 23m at 2.1 g/t gold
LR-DDH-008 18m at 2.7 g/t gold
LR-DDH-011 45m at 1.1 g/t gold
LR-DDH-012 49m at 2.4 g/t gold (including 18m at 5.4 g/t gold)
LR-DDH-013 80m at 1.1 g/t gold (including 10m at 2.8 g/t gold)
LR-DDH-016 69m at 1.5 g/t gold (including 15m at 2.5 g/t gold)
The drilling program at Luna Roja aimed to test the sub-surface extension of surface gold mineralization identified in saw-cut channel samples which returned significant intersections including, 40.65 meters at 2.5 grams per tonne, 23.5 meters at 5.1 grams per tonne, 12.0 meters at 7.1 grams per tonne and 5.5 meters at 12.2 grams per tonne gold. These drilling results indicate that gold mineralization remains open at depth (down to 150 meters vertical depth, LR-DDH-005) and open along-strike to the northwest and southeast. The southernmost and final drill hole of the program, LR-DDH-017 is located approximately 450 meters to the southeast of previous drilling and intersected 8 meters at 0.9 grams per tonne gold from surface. Geological mapping suggests that LR-DDH-017 was collared into a window of skarn mineralization located stratigraphically below an overlying sequence of marble and skarnoid rocks. These drilling results, together with geological observations, suggest that gold mineralization at Luna Roja extends along an antiformal fold hinge, significantly southwards and under cover, for a total mineralized system of approximately 1400 meters in strike distance.
Further drilling is planned at Luna Roja following geophysics to aid in identifying further drill targets to the south and under cover.
Skarn-related gold mineralization at Luna Roja appears to be associated with, breccia, veining and selective replacement of carbonate rocks on the upper limb and in the hinge-zone of a northwest trending, thrust-related, inclined antiform. Early-stage gold-bearing pyroxene garnet skarn occurs along selective carbonate units and aligned along a pressure-solution-cleavage particularly close to the hinge-zone of the mapped antiform. Pyroxene garnet skarn is overprinted by a generally higher-grade gold mineralized, magnetite, carbonate vein and breccia-related skarn. Gold is related with elevated tungsten, zinc and manganese.
We are the largest title and title application holder in Colombia with quality gold and copper exploration projects located in two main regions; The Northern Block, encompassing the prolific Middle Cauca belt, and the Southern Block, incorporating the most prospective and under-explored regions of the Andes.
Operating under the structure of a 50-50 strategic alliance with HEMCO Mineros Nicaragua, we are the exploration largest license holder in the Country. Currently, the exploration work in Nicaragua is focused on drill-testing three drill-permitted gold and copper-gold projects.
