Silver Hill Copper and Silver Project

Silver Hill Project

Trigon Metals signs definitive agreement to acquire the high potential ‘Silver Hill’ copper-silver exploration project in Morocco.



  • Favourable jurisdiction for mining.
  • Home to Africa’s major silver mines (Imiter, Zgounder).
  • Established industry producing at a rate of approximately 40 million tonnes of minerals per year.
  • Produces 90% of the world’s supply of phosphates, and extracts copper, cobalt, gold silver and zinc.
  • Friendly business environment with a strong mining history, but very little systematic modern exploration.
  • The mining sector creates over 41,000 direct job positions.


The Silver Hill Project is a 16kmproperty in the Anti-Atlas region of Morocco.  The Project is located at a regional address well known for base metals occurrences in Morocco.  Morocco has a mining history that stretches over 100 years and is well known for being a mining friendly jurisdiction. Preliminary surface exploration shows copper and silver mineralization at high grades distributed over a wide surface area. Slags from ancient workings indicate historical large-scale mining for silver.

“We are excited to introduce another high-grade copper asset to Trigon’s portfolio. New areas of copper production are important as production declines from the Andean resources on which the world has come to depend for the last 30 years. We aim to explore and develop new copper resources in mining-friendly African jurisdictions. Strong silver grades at Silver Hill fit nicely with the Kombat mine, our asset in Namibia, where silver is already a meaningful by-product credit,” commented Jed Richardson, Trigon President & CEO.

Geology, Exploration & Geography

exploration silver hill
Locally referred to as, Aourir N’kort (Silver Hill in the Berber language), early basic surface exploration of the Project shows that it is a high-grade exploration project showing mineralization at high grades distributed over a wide surface area. Ancient slags grading 2.5% Cu are distributed widely across one third of the concession surface, indicating a history of very ancient mining and primitive metal recovery.

The presence of historical mine shafts measuring less than 20 metres in depth demonstrate that historical activity only concerned the superficial part of the mineralization and that the potential at depth remains high. Trigon is optimistic that this project and its accompanying team will emerge as a new source of growth, excitement for the Company, and value for its shareholders.

The local partners (the Vendors) made use of a small under-powered drill and were not able to drill through all of the mineralized sequence, however intercepts of high copper and silver were recorded in the shallow holes (1m at 9.35% Cu and 623g/t Ag or 4m at 3.67% Cu and 263 g/t Ag at 35m depth).

Assay Results

The results reported are from exploratory drilling undertaken by Trigon’s acquisition target Technomine Africa SARL (“Technomine”), based on the local company’s knowledge of the area.

For the purposes of the latest preliminary drilling, Technomine had use of a small underpowered rig only capable of drilling shallow holes, of which three of the four reached the targeted mineralized structure, and two of the four ended in mineralization.  The recent results demonstrate good mineralization over a larger than expected horizon. To advance the project, Trigon will utilize these encouraging results to design and implement a full exploration program to required standards.

The latest results are highlighted by:

  • S1 – Silver Hill Hole 1: intercepted 13.5 metres grading 71.5 g/t silver and 1.08% at 26.5 to 40 metres down the hole, drill core ended in mineralization. Within the drill intercept was 2.5 metres grading 266.6 g/t silver and 3.87% copper.
  • S3 – Silver Hill Hole 3: intercepted 7.0 metres grading 48.6 g/t silver and 0.75% copper at 25 to 32 metres down the hole, the hole ended at 35.5 metres.  Within the drill intercept was 1.5 metres grading 122 g/t silver and 1.59% copper.
  • S5 – Silver Hill Hole 5: intercepted 5.0 metres grading 18.9 g/t silver and 1.49% copper at 29 to 34 metres down the hole, drill core ended in mineralization.

Holes were drilled at a 70° angle and drill intercepts are presumed to represent true width of the structure. Silver Hill Hole S2 did not reach the mineralized layer. The hole reached a maximum depth of 36 metres.

As indicated above (see Table 1 – Silver Hill Drill Results), work has begun on site at Silver Hill for Trigon’s own program to test the extent of this mineralization. Trigon has planned drilling and systematic surface sampling to test the down dip extension of the mineralization delineated in this drilling, to test the relationship between the upper structure (focus of the reported drilling) and the two other structures identified in early surface sampling (see Figure 1 – Silver Hill Global Map), and connect the upper structure to what appears to be lateral extension, identified by ancient workings almost 1.5 km to 2 km away.
