Locksley Resources (OTCQB:LKYRF) announced plans to expand its geological and structural mapping program within the North Block of the Mojave Project in California. The company will focus on four priority areas, with two targeting rare earth elements (REE) potential and two focusing on antimony mineralization extensions from the Desert Antimony Prospect.

The program builds on the company's established REE potential at El Campo, which has shown high-grade rock chip results of up to 12.1% TREO and Nd/Pr up to 3.19%. The North Block's strategic location adjacent to MP Materials' Mountain Pass Mine, the only operating rare earths mine in the U.S., positions Locksley to potentially expand its critical minerals footprint across the underexplored 20 sq km area.

Locksley Resources (OTCQB:LKYRF) ha annunciato l'espansione del programma di mappatura geologica e strutturale nel North Block del Mojave Project in California. L'azienda si concentrerà su quattro aree prioritarie, con due rivolte al potenziale di elementi delle terre rare (REE) e due focalizzate sull'estensione della mineralizzazione di antimonio dal Desert Antimony Prospect.

Il programma si basa sul potenziale REE già dimostrato a El Campo, che ha registrato risultati di campionamento di alta qualità fino al 12,1% TREO e rapporti Nd/Pr fino a 3,19%. La posizione strategica del North Block, adiacente alla miniera Mountain Pass di MP Materials, l'unica miniera di terre rare attiva negli Stati Uniti, pone Locksley in posizione di poter espandere il suo impegno nei minerali critici nell'area poco esplorata di 20 km².

El programa se apoya en el potencial REE ya identificado en El Campo, que mostró resultados de muestreo en roca de alta ley de hasta 12,1% TREO y relaciones Nd/Pr de hasta 3,19%. La ubicación estratégica del North Block, contigua a la mina Mountain Pass de MP Materials, la única mina de tierras raras en operación en Estados Unidos, sitúa a Locksley en posición de ampliar su presencia en minerales críticos en la zona poco explorada de 20 km².

Locksley Resources (OTCQB:LKYRF)는 캘리포니아 Mojave 프로젝트의 North Block에서 지질 및 구조 매핑 프로그램을 확대할 계획을 발표했습니다. 회사는 네 개의 우선 지역에 주력할 예정이며, 그중 두 곳은 희토류 원소(REE) 잠재력, 나머지 두 곳은 Desert Antimony Prospect에서 연장되는 안티몬 광물화에 초점을 맞춥니다.

이 프로그램은 El Campo에서 확인된 REE 잠재력을 기반으로 하며, 해당 지역에서는 암석 시료에서 최대 12.1% TREO와 Nd/Pr 비율 최대 3.19%라는 고품위 결과가 보고되었습니다. North Block은 미국에서 유일하게 가동 중인 희토류 광산인 MP Materials의 Mountain Pass Mine과 인접해 있어, Locksley가 미개척 20km² 지역에서 전략 광물 보유 영역을 확장할 수 있는 위치에 있습니다.

Locksley Resources (OTCQB:LKYRF) a annoncé son intention d'étendre son programme de cartographie géologique et structurale dans le North Block du Mojave Project en Californie. La société se concentrera sur quatre zones prioritaires, dont deux visant le potentiel en éléments de terres rares (REE) et deux portant sur l'extension de la minéralisation en antimoine issue du Desert Antimony Prospect.

Le programme s'appuie sur le potentiel REE déjà identifié à El Campo, qui a livré des résultats d'échantillonnage rocheux de haute teneur atteignant 12,1% TREO et des rapports Nd/Pr allant jusqu'à 3,19%. La situation stratégique du North Block, adjacente à la mine Mountain Pass de MP Materials, la seule mine de terres rares en activité aux États-Unis, place Locksley en position d'étendre son empreinte en minéraux critiques sur la zone peu explorée de 20 km².

Locksley Resources (OTCQB:LKYRF) gab Pläne bekannt, sein geologisches und strukturelles Kartierungsprogramm im North Block des Mojave-Projekts in Kalifornien auszuweiten. Das Unternehmen konzentriert sich auf vier Prioritätsgebiete, wobei zwei auf das Potenzial für Seltene Erden (REE) abzielen und zwei auf die Ausdehnung der Antimonmineralisierung vom Desert Antimony Prospect.

Das Programm baut auf dem bereits aufgezeigten REE-Potenzial bei El Campo auf, das hochgradige Gesteinsproben mit bis zu 12,1% TREO und Nd/Pr-Verhältnisse bis zu 3,19% gezeigt hat. Die strategische Lage des North Block unmittelbar neben der Mountain Pass Mine von MP Materials, der einzigen derzeit betriebenen Seltene-Erden-Mine in den USA, versetzt Locksley in die Lage, sein Engagement in kritischen Mineralien über das wenig erforschte Gebiet von 20 km² auszuweiten.

Positive
  • Strategic location adjacent to MP Materials' Mountain Pass Mine, the only operating rare earths mine in the U.S.
  • High-grade rock chip results at El Campo showing up to 12.1% TREO
  • Large exploration potential across 20 sq km of underexplored territory
  • Four priority areas identified for mapping campaign
Negative
  • Early-stage exploration with no proven resources yet
  • Results from the mapping program not guaranteed to yield viable targets

Key Highlights

  • Structural and geological field mapping campaign expected to commence late this month to define high priority rare earth elements (REE) and antimony target areas.
  • Four priority areas to be mapped with two focusing on REE potential within the North Block of the Mojave Project and two targeting strike extensions from mineralization identified at the Desert Antimony Prospect.
  • Planning and contractor engagement underway for focused magnetic, radiometric and gravity surveys to provide additional high-resolution data sets for target refinement and prioritization.
  • North Block offers significant potential for further polymetallic discoveries across its underexplored 20 sq km, expanding the critical minerals footprint of the Mojave Project.
  • Technical team advancing high priority targets to build on established REE potential at El Campo.

SAN BERNARDINO, Calif., Aug. 13, 2025 /PRNewswire/ -- Locksley Resources Limited (ASX: LKY; OTCQB: LKYRF) announced it will commence an expanded geological and structural mapping program within the North Block of the Mojave Project in California. The field program, expected to commence later this month, will focus on expanding knowledge gained from the recent structural mapping program completed at the Desert Antimony Prospect. Additionally, it will include regional mapping across prospective areas within the North Block claims with potential for REE mineralization. Additional details can be found here: https://cdn-api.markitdigital.com/apiman-gateway/ASX/asx-research/1.0/file/2924-02977959-6A1278092&v=4a466cc3f899e00730cfbfcd5ab8940c41f474b6.

These new mapping target areas complement the established prospect at El Campo, which has high grade rock chip results of up to 12.1% TREO and Nd/Pr up to 3.19%. "The program is set to expand REE potential into the North Block, which lies immediately adjacent to MP Materials' Mountain Pass Mine, the only rare earths mine currently operating in the U.S.," said Nathan Lude, chairman of Locksley Resources. He added that the recent decision by both the U.S. Department of Defense and Apple to make strategic investments in MP Materials highlight the recognition by government and industry of the importance of and need for critical minerals located within the U.S.

The additional field mapping programs are expected to provide additional field data that may provide new REE targets for follow up later in the year.

About Locksley Resources Limited

Locksley Resources is an Australian-based explorer focused on critical minerals and base metals, with assets in both the United States and Australia. The company is actively advancing exploration of its US asset.  The Mojave Project in California, targeting rare earth elements (REEs) and antimony, is located in the Mojave Desert in California and comprises more than 250 claims. The North Block area directly abuts claims held by MP Materials, while El Campo lies along strike of the Mountain Pass Mine and is enveloped by MP Materials' claims. In addition to rare earths, the Mojave Project hosts the historic "Desert Antimony Mine," which last operated in 1937. Despite the United States currently having limited domestic antimony production, demand for the metal runs high due to its essential role in defense systems, semiconductors and metal alloys. Locksley's position is strengthened by rising geopolitical urgency to diversify supply chains away from China, the global leader in both REE and antimony production. The Company's Mojave Project is uniquely positioned to align with U.S. strategic objectives around critical mineral independence and economic security.
