• High resolution magnetic drone survey wraps up at Horse Rocks
  • Survey shows correlation between magnetic low features and mapped pegmatites
  • Mineralogical assessment has identified the presence of fine grained weathered spodumene and drilling will begin shortly to test this LCT system

 

A high-definition survey has exceeded expectations at the Horse Rocks lithium project in WA, uncovering multiple new target areas where clusters of intense magnetic ‘lows’ indicate potential pegmatite bodies at depth.

Recently listed lithium-gold explorer Lord has two key projects: Horse Rocks (lithium) and Gabyon (gold), both in WA.

Early stage work has defined a bunch of targets at Horse Rocks, nestled between Mt Marion — owned by major miner Mineral Resources (ASX:MIN) — and $136m takeover target  Essential Metals (ASX:ESS).

According to Lord Resources (ASX:LRD) the 1,076-line kilometre survey delivered magnetic data of ‘exceptional’ quality, producing high resolution images that provide clear and detailed magnetic view of the project.

Mapped pegmatites often correlate with magnetic low features, the company says.

LRD says these new target areas are now high priority targets for field reconnaissance and potential drill testing.

 

Additional targets yet to be field mapped

“The intense magnetic low features are very compelling, creating additional targets in areas that are yet to be field mapped,” Lord exploration manager Georgina Clark says.

“This data has assisted with ongoing detailed litho-structural review of the Horse Rocks lithium project, which has assisted in the design of the upcoming Phase 2 drilling.

“The technical team is eager to be back in the field drilling the Horse Rocks.”

Ongoing geophysical interpretation of the drone magnetic survey is currently underway, with a reconnaissance mapping trip in progress to assess the targets at surface.

 

Upcoming drilling

Meanwhile, selected drill chips from the Lord’s initial RC drill program were submitted for automated mineralogy analysis utilising SEM-based TESCAN Integrated Mineral Analysis (TIMA) and Laser Induced Breakdown Spectroscopy (LIBS).

The TIMA analysis of some drill chips from 23RC026 12m (0.29% Li2O) identified small amounts of fine grained spodumene and cookeite, within weathered quartz crystals.

There were also drill chips composed of secondary lithium minerals, including bityite and zinnwaldite, which can form as a result from weathering of primary lithium minerals (such as spodumene, petalite and lepidolite).

Drilling will commence imminently post heritage survey to test the potential of this LCT-system.
