Sampling shows abundant gold at Botswana’s Tati project

08 february 2024

Power Metal Resources, which recently conducted geochemical soil sampling, has verified the occurrence of three substantial gold-in-soil geochemical anomalies at the Tati gold property in Botswana.

The results confirm the ongoing consistency of the 8-kilometre gold trend at Tati.

The anomalies consist of the Northwest (NW), the Southwest (SW), and the Cherished Hope (CH) abnormalities.

The exploratory results encompass a comprehensive soil sample campaign conducted at Tati in 2023, which is a crucial stage in the exploration process for identifying regions with promising gold mineralization and uncovering new gold deposits.

A total of 446 soil samples were collected from four distinct grid areas.

The primary objective of the programme was to assess the presence of other gold-mineralised areas along the 8-kilometre gold-mineralised trend that stretches from northwest to southeast through Tati.

Out of the 446 samples collected, three showed gold levels exceeding 500 parts per billion (ppb). These samples had individual gold assay findings of 568 ppb, 831 ppb, and 1,076 ppb, which is equivalent to 1.08 grammes per tonne (g/t) of gold.

Twenty-nine samples have yielded gold concentrations of 100 ppb or above, with the majority of these samples being part of the CH anomaly.

“This gold soil sampling programme has delivered quite remarkable results in terms of a confirmation of the significant area mineralised and also the consistency of positive results across the areas tested,” said Power Metal Resources chief executive Sean Wade.

“Each stage of work at Tati has delivered extremely positive findings, and we are more confident than ever that the project holds very significant value for the company.”
