Zeus Resources (ASX:ZEU) makes a Herculean discovery in Morocco with antimony grades topping 46%
April 9, 2025While lithium and rare earths have hogged the headlines, a lesser-known but increasingly strategic metal—antimony—just elbowed its way back into the spotlight.
Courtesy of Zeus Resources (ASX:ZEU), the Casablanca Antimony Project in central Morocco has delivered eye-watering rock chip assays peaking at 46.52% Sb, a result more often read as a typo than geological fact.
Antimony, used in flame retardants, semiconductors, and increasingly in battery alloys, is on several critical minerals lists globally, including Australia’s.
With China historically dominating supply, the search for alternative, politically stable sources has become more than a resource play—it’s now strategic geopolitics in action.
Highlights from Zeus’ due diligence program include:
-
46.52% Sb (Sample BK-ZMX 017)
-
40.80% Sb (Sample BK-ZMX 008)
-
35.59% Sb (Sample BK-ZMX 018)
-
Continuity of mineralisation over a 4km strike length

Sampling across two outcropping quartz-stibnite veins, with visible mineralisation
“The site visit has reinforced our confidence in the scale and quality of the Casablanca Antimony Project,” Zeus Resources Executive Director Hugh Pilgrim said. “The combination of high-grade mineralisation at surface, favourable geology, and strong local support positions us well to move rapidly into active exploration.”
That last point matters.
While the assays are stellar, execution often hinges on jurisdiction—and Morocco is increasingly seen as a mining-friendly environment, with established permitting and a willingness to engage foreign investment.
The company’s deal structure is also worth noting: Zeus holds an option to acquire six exploration licences from Ashgill Morocco, subject to shareholder approval.
That’s a prudent move—allowing for low-risk entry into a compelling project before significant capital is deployed.
Geologically, the mineralisation occurs within a dilation zone of the regional Smaala-Oulmes Fault system, with veins cutting through metamorphosed shale and sandstone.
Structural mapping indicates steeply dipping quartz-stibnite veins—prime real estate for further geophysics and drill targeting.
It’s early days, and rock chips don’t make a mine, but the grades here suggest more than just a speculative punt.
If follow-up drilling confirms continuity at depth, Zeus may have stumbled across one of the more compelling critical mineral plays outside China in recent memory.
Takeaway:
With assays resembling the kind of grades last seen in dusty historical records, Zeus isn’t just talking up a critical minerals angle—it’s got the data to match.
Keep an eye on how fast this Moroccan story develops. The global antimony supply chain just got a serious jolt.
