Emerita Resources Corp. (EMO:TSX.V; EMOTF:OTCQB; LLJA:FSE) has commenced a 1,536-kilometer helicopter-borne time-domain electromagnetic and magnetic (HTEM) geophysical survey across its Iberian Belt West (IBW) project and the adjacent San Antonio exploration area in southern Spain. The program, scheduled to begin in December 2025, will utilize HTEM technology to detect electrical conductivity and magnetic responses in subsurface rock formations up to 500 meters deep.
The survey will include high-resolution mapping of known deposits La Romanera, El Cura, and La Infanta, all of which are part of a mining license application currently underway. Data from these zones will provide comparative signatures to identify additional mineralization in lesser-explored areas such as Los Silos, San Jose, Penuelas, and Terra Nova. According to the company, "Covering areas of known and suspected massive sulphide occurrences with the same investigation will allow the Company to compare the signals of the well-studied deposits with identified prospects and untested areas."
Flight lines are spaced at 100 meters and guided by differential GPS. The survey work is being conducted by Xcalibur Smart Mapping, with QA/QC and data interpretation overseen by Intelligent Exploration of Canada. Emerita aims to finalize data collection by the end of December 2025, weather permitting, with initial processed results expected in January 2026 and full analysis beginning shortly thereafter.
According to Joaquin Merino, P.Geo., President of Emerita and the project's Qualified Person as defined by National Instrument 43-101, the integration of HTEM data will enhance the company's ability to prioritize drill targets across its expansive land position.
Polymetallic Sector Activity Highlights Market Tightness and Supply Uncertainty
According to SMM's Zinc/Lead Market Weekly Update from November 28, the imported zinc concentrate treatment charge (TC) index dropped by 11.8% week-over-week to US$61.25 per dry metric ton. This marked a significant decline from the October level of over US$110. The report noted that "smelter's inventory levels dropped, but they still have solid demand due to the need to prepare for their winter inventory." The shift in purchasing from domestic to imported material was attributed to intensified competition for local sources.
On the lead side, SMM reported that the average spot TC remained unchanged at negative US$135 per dry metric ton, reflecting a persistently tight market. The update stated, "Spot market remains severely tight with little signal for improvement."
Canaccord Genuity maintained its view that the combination of exploration progress and near-term legal developments continued to support its Speculative Buy recommendation.
Inventories of lead concentrate at major Chinese ports fell to 15,300 tonnes, a week-over-week drop of 5,600 tonnes, while social inventories across seven surveyed regions decreased to 35,000 tonnes. The report linked the depletion to "maintenance at primary smelters" and a "weaker production appetite at secondary smelters after the price drop."
Bloomberg wrote on November 30 that copper reached a new record high on the London Metal Exchange, rising as much as 1.3% to US$11,334 per ton. The article connected the price increase to mounting concerns over a potential global supply shortfall. It also noted that a rush to ship copper to the United States in advance of possible tariffs was "set to exacerbate shortfalls elsewhere as miners struggle to keep up with demand."
In a broader industry overview, ScienceDirect provided historical and technical context for lead and zinc mining, noting that these metals frequently occur together in volcanogenic massive sulphide (VMS) and sedimentary exhalative (SEDEX) deposits. It explained that while many VMS deposits contain finely grained minerals that are challenging to process, those that have undergone recrystallization tend to yield higher recoveries through conventional beneficiation. The report also detailed the pyrometallurgical methods typically used to extract lead from galena, its primary ore, and highlighted the importance of secondary recovery, such as from battery scrap, in maintaining lead supply.
Laying the Groundwork for Exploration Acceleration
Emerita's airborne survey initiative builds upon recent momentum across its flagship IBW project, a 1,545-hectare land package that hosts three high-grade polymetallic deposits. As of the February 2025 mineral resource estimate, the project includes 18.96 million tonnes (Mt) of Indicated resources grading 8.44% zinc-equivalent (ZnEq) and 6.80 Mt of Inferred resources grading 8.72% ZnEq. The deposits remain open for expansion and benefit from near-surface geometries, facilitating lower-cost exploration and potential development planning.
The timing of the HTEM survey aligns with several key project catalysts. As outlined in the company's November 2025 investor presentation, milestones scheduled between late 2025 and 2026 include a prefeasibility study, updated metallurgical testing, and ongoing public consultations tied to the Environmental Impact Study and Mining License application. The addition of detailed geophysical data could enhance targeting precision for drill campaigns aimed at both expanding known resources and testing new targets across the San Antonio and IBW claims.
Notably, the San Antonio property, which borders IBW to the west, hosts multiple past-producing mines and historic high-grade copper zones. According to the company, grab samples taken from areas such as San Jose and Penuelas returned copper values as high as 13.2%. The HTEM survey will be the first modern, large-scale geophysical assessment over this highly prospective ground.
