Power Metal (AIM:POW) Tati Project, Botswana – 2023 Exploration Underway

Power Metal Resources PLC (LON:POW) the London listed exploration company seeking large-scale metal discoveries across its global project portfolio announces next stage exploration on its 100% owned and operated Tati Gold Project (“Tati” or the “Project”) located within the Tati Greenstone Belt near Francistown, Botswana, is underway.


–  To confirm the presence of a large gold-bearing system and delineate a deposit, through follow-on work over a larger portion of the approximately 8km long gold-in-soil anomaly.

–  Through Power Metal’s largest and most comprehensive exploration campaign across the Tati Project, to date.

 Programme will include mechanised trenching, geophysics surveys, high-resolution geochemical surveys, reverse circulation (“RC”) drilling and diamond core drilling.

 Both geophysical survey work and mechanised trenching are currently underway, with further soil sampling scheduled and RC and diamond drilling to follow on in order to test the emerging high priority gold targets.

Paul Johnson, Chief Executive Officer of Power Metal Resources plc commented:  

 The exploration campaign now underway is a key step forward for Power Metal with the various planned works tailored towards a single objective, namely the discovery of a large gold deposit.

Our exploration programmes in 2021 and 2022 have built a robust picture of the Project’s potential and we are particularly excited as we proceed with the next stage of exploration – the largest ever completed on the Project by Power Metal.

So far, we have confirmed near surface high-grade gold from reverse circulation drilling, conducted last year, which intersected the quartz reef structure near the Cherished Hope mine and delivered high-grade and bonanza-grade gold results. Figure 1 below provides an overview of those results.

Within the table immediately below is an overview of the work we are planning to undertake, with explanatory notes on the various steps to be implemented.”


Exploration Work

Rationale and Targeted Outcome


A circa 500 metre mechanised trenching programme (underway).

Trenching will be focused along various strike-length extensions of the known outcropping gold mineralised quartz reef structure.

Quartz reef as well as mineralised wall rock will be sampled when intersected within the exposed trenches.

This work will look to extend the already known strike length extension of the main quartz reef structure at the Cherished Hope gold mine (the “Cherished Hope”) within the Project licence area. The quartz reef currently remains open towards the northwest and southeast as well as down dip.

If the main quartz reef is successfully intercepted, the trenching would highlight quartz reef continuity between known historical workings at Cherished Hope, as well as to the northwest and southeast of current (~175m) strike length extents as defined by the recently completed RC drilling campaign.

By extending the surficial expression of the mineralised quartz reef structure beyond the currently defined 175m strike length, Power Metal will be able to follow up drill test these areas to prove the downdip continuity, therefore increasing the size of the mineralised system in multiple dimensions.


High-resolution soil geochemistry programme focussed on approximately 3km of strike-length (see red area highlighted on figure 1 below).

Approximately 500-600 individual soil samples are planned with follow up assay testing of samples.

Soil samples will be collected along a grid which will be focussed northwest of the 2022 RC drilling area. The goal is to improve the resolution and definition over several kilometres of the currently defined ~8km long gold-in-soil anomaly.

Historical soil sampling completed over the majority of the Tati Project was undertaken by previous operators along 400m spaced lines at 40m sample spacing.

This programme looks to infill the line spacing so that the definition and location of already proven Au-in-soil anomalies is vastly improved.

This work will then allow Power Metal to follow up with more focussed next exploration steps which could include trenching and RC drilling of these new areas during subsequent work programmes.

By completing this work, a much larger percentage of the 8km long Au-in-soil anomaly can move to next exploration steps therefore increasing the overall attractiveness of the Project as well as the size of the mineralised footprint.


A ground magnetometer geophysics survey focussed on the northwestern strike length extension of the Cherished Hope Mine (underway).

The goal of the magnetometer survey is to provide high-resolution imaging of any structures or geology which may have had an influence on the emplacement of mineralised quartz reef structures.

Prospective structures and geology identified by the magnetometer survey can then be upgraded to further work streams which may include geochemical sampling, trenching and RC & diamond drilling.


~15 RC drillholes are planned to an average planned  depth of ~100m for ~1,500m in total.

This RC programme is designed to test for the along strike and down dip extension of the main mineralised quartz reef structure.

The mechanised trenching programme will be completed prior to the RC drilling and will look to extend the known surficial expression of the mineralised quartz reef structure. Once the surface expression is well defined by trenching, RC drilling will be employed in order to test for the down dip or depth extension of the quartz reefs within the subsurface.

The goal is to prove continuity in the widths as well as grades of the quartz reef structure from surface down to depths targeted by the RC drilling.


~5 diamond drill holes are planned to an average expected depth of 100m for ~500m in total.

The diamond drilling programme is designed to drill test select portions of the quartz reef structures which were previously successfully delineated by the RC drilling conducted during fall 2022.

Diamond drilling provides full core rock samples, and therefore valuable information about structure, geology, and the nature of gold mineralisation.

The information extracted from diamond drilling will allow the company to gain a better understanding of the mineralised quartz reefs and surrounding wall rocks. This data will be important as exploration continues to develop across the broader Tati Project.


(1)  RC drilling involves a “hammer” piston which repeatedly strikes the target rock. Simultaneously, a powerful drill-bit at the end made of tungsten rotates at high speed. This creates small chips of rock known as drill cuttings that are sucked up with a vacuum and transported to a cyclone at the surface through dedicated tubes. The chips are then sorted into a variety of sampling bags, each of which represents a certain depth section of the drill hole. These bags are then sent off directly to the assay lab where their mineral content can be analysed. In turn, a picture of the rock types the hole encountered throughout its length can be established.

(2)  Diamond core drilling involves rotating a hollow drill bit embedded with diamonds into the ground to a certain depth before extracting the solid, intact core recovered for analysis.
