Barton Gold Holdings (OTCQB:BGDFF) has completed an expedited soil sampling program covering approximately 1.9km² at its Tolmer silver discovery within the South Australian Tarcoola Gold Project. The program collected ~380 samples with results expected in September 2025.

The sampling area extends around the recently expanded 2,882m RC drilling program and covers a broader area of ~1,700 metres by ~1,100 metres. This follows Barton's previous discovery of significant silver mineralization, which included exceptional intersections of 6m @ 4,747 g/t Ag from 46m, 14m @ 434 g/t Ag from 46m, and 4m @ 1,417 g/t Ag from 9m.

Barton Gold Holdings (OTCQB:BGDFF) ha completato un programma accelerato di campionamento del suolo che copre circa 1,9 km² presso la sua scoperta di argento Tolmer all'interno del progetto aurifero Tarcoola in Australia Meridionale. Il programma ha raccolto circa 380 campioni, con risultati attesi per settembre 2025.

L'area di campionamento si estende intorno al recentemente ampliato programma di perforazione RC di 2.882 m e copre un'area più ampia di circa 1.700 metri per 1.100 metri. Questo segue la precedente scoperta di Barton di mineralizzazione significativa di argento, che includeva intersezioni eccezionali di 6 m a 4.747 g/t Ag da 46 m, 14 m a 434 g/t Ag da 46 m e 4 m a 1.417 g/t Ag da 9 m.

El programa recolectó alrededor de 380 muestras, con resultados esperados para septiembre de 2025.

El área de muestreo se extiende alrededor del recientemente ampliado programa de perforación RC de 2.882 m y cubre un área más amplia de aproximadamente 1.700 metros por 1.100 metros. Esto sigue al descubrimiento previo de Barton de una mineralización significativa de plata, que incluyó intersecciones excepcionales de 6 m a 4.747 g/t Ag desde 46 m, 14 m a 434 g/t Ag desde 46 m y 4 m a 1.417 g/t Ag desde 9 m.

Barton Gold Holdings (OTCQB:BGDFF)는 남호주 타쿨라 금 프로젝트 내 톨머 은 발견 지역에서 약 1.9km²에 걸친 신속 토양 샘플링 프로그램을 완료했습니다. 이 프로그램은 약 380개의 샘플을 수집했으며 결과는 2025년 9월에 발표될 예정입니다.

샘플링 지역은 최근 확장된 2,882m RC 시추 프로그램 주변에 걸쳐 있으며, 약 1,700미터 x 1,100미터의 넓은 지역을 포함합니다. 이는 Barton이 이전에 발견한 중요한 은 광화 구간에 따른 것으로, 46m 지점에서 6m @ 4,747 g/t Ag, 46m 지점에서 14m @ 434 g/t Ag, 9m 지점에서 4m @ 1,417 g/t Ag의 뛰어난 교차 구간을 포함합니다.

Barton Gold Holdings (OTCQB:BGDFF) a achevé un programme accéléré d'échantillonnage du sol couvrant environ 1,9 km² sur sa découverte d'argent Tolmer dans le cadre du projet aurifère Tarcoola en Australie-Méridionale. Le programme a collecté environ 380 échantillons, dont les résultats sont attendus en septembre 2025.

La zone d'échantillonnage s'étend autour du programme de forage RC récemment étendu de 2 882 m et couvre une zone plus large d'environ 1 700 mètres par 1 100 mètres. Ceci fait suite à la précédente découverte par Barton d'une minéralisation argentifère significative, incluant des intersections remarquables de 6 m à 4 747 g/t Ag à partir de 46 m, 14 m à 434 g/t Ag à partir de 46 m, et 4 m à 1 417 g/t Ag à partir de 9 m.

Barton Gold Holdings (OTCQB:BGDFF) hat ein beschleunigtes Bodenprobenprogramm abgeschlossen, das etwa 1,9 km² bei seiner Tolmer-Silberentdeckung im süd-australischen Tarcoola-Goldprojekt abdeckt. Das Programm sammelte etwa 380 Proben, deren Ergebnisse im September 2025 erwartet werden.

Das Probenahmegebiet erstreckt sich um das kürzlich erweiterte 2.882 m RC-Bohrprogramm und umfasst ein größeres Gebiet von etwa 1.700 Metern mal 1.100 Metern. Dies folgt auf Bartons frühere Entdeckung signifikanter Silbermineralisierung, die außergewöhnliche Abschnitte von 6 m bei 4.747 g/t Ag ab 46 m, 14 m bei 434 g/t Ag ab 46 m und 4 m bei 1.417 g/t Ag ab 9 m beinhaltete.

Positive
  • Discovery of high-grade silver mineralization with exceptional grades up to 4,747 g/t Ag
  • Expansion of RC drilling program by 50% to cover ~400m x 250m area
  • Potential for larger mineralized footprint across 1.9km² area
Negative
  • Results from both soil sampling and RC drilling programs still pending
  • Timeline for complete analysis extends to September 2025

HIGHLIGHTS

  • Tolmer high-grade silver discovery: expedited soil geochemistry program completed over ~1.9km2 area surrounding recently expanded reverse circulation (RC) drilling program1

ADELAIDE, AUSTRALIA / ACCESS Newswire / July 13, 2025 / Barton Gold Holdings Limited (ASX:BGD)(FRA:BGD3)(OTCQB:BGDFF) (Barton or Company) is pleased to confirm that an expedited soil sampling program has been completed over a ~1.9km2 area surrounding the new 'Tolmer' high grade silver discovery at the Company's South Australian Tarcoola Gold Project (Tarcoola). ~380 samples have been collected with assay results expected during September 2025.1

Commenting on the geochemical program, Barton Managing Director Alexander Scanlon said:

"We recently expanded our Tolmer 'silver zone' drilling by ~50% to cover a ~400 metre by ~250 metre area based, in part, upon further geological surface reconnaissance. This program extends that reconnaissance to a broader area of ~1,700 metres by ~1,100 metres to see if we can potentially identify a larger mineralised footprint."

Program background

Barton identified Tolmer as a high-grade gold discovery in August 2024, and subsequently identified a new 'silver zone' ~500m west in a line of seven discovery holes with globally significant assays including 6m @ 4,747 g/t Ag from 46m, 14m @ 434 g/t Ag from 46m and 4m @ 1,417 g/t Ag from 9m.2

2,882m RC drilling was completed during June 2025 to test extensions of mineralisation in all directions, with the current geochemical sampling intended to potentially map a broader surface footprint.3
