Induced Polarisation Survey Identifies Large Anomaly at Yerbas Buenas

• Induced Polarisation survey over prospective copper & gold area completed

• Survey has identified large structure that extends from surface to over 400m in depth and is open to the east, south & north

▪ Second potential large structure identified to south

Freehill Mining Limited (“Freehill” or “the company”, ASX:FHS) is pleased to report the completion of the first round of geophysics over the copper prospective northern portion of its Yerbas Buenas project.

Last year Freehill commissioned ground magnetics and induced polarisation (IP) surveys at the Yerbas Buenas Project in Region IV, Chile. The IP survey targeted a potential source of significant copper mineralisation which is common at surface in the area which contains numerous artisanal copper and gold workings.

Data review work completed shows that the IP survey has outlined moderately strong chargeability anomalies in the north east portion of the survey area. The shallow portion of the anomaly is located in a pronounced quebrada (ravine) where the chargeable material may be located near surface.

High resistivities are associated with both the chargeability anomaly in the north-east part of the grid and with most of the strong magnetic anomalies in the northern portion of the grid. A significant break in resistivities immediately west of the major magnetic anomalies is indicative of a major structure or contact.

The geology of Yerbas Buenas shows a complex lithology consisting primarily of various types of andesites on the eastern portion of the grid and mixed andesites and diorites on the western portion of the grid.

Induced Polarisation Structure

Figure 1 shows the relative location of the magnetic structure YB7 relative to the newly identified IP structure. The map should be viewed in conjunction with Figure 3 that provides detailed plan views of the Induced Polarisation survey at varying depths. An additional structure to south appears at 200m depth and a new survey is currently under way to assess its size and geometry.

Figure 1- Yerbas Buenas Project displaying Ground Magnetic RTP Image & Location of IP Anomaly

Copper and gold sulphide mineralisation is common at a number of nearby deposits including Higuera, Dominga, and Caballo Blanco. Typically, the copper and gold mineralisation is located within or near the magnetite zones, but is generally associated with sulphide mineralisation events rather than the magnetite.

The copper and gold zones are often controlled both structurally and stratigraphically, with resulting complex geometries that can be difficult to understand during the initial stages of exploration. IP surveys are routinely used to identify sulphide mineralisation prior to drilling.

The Yerbas Buenas IP anomaly is located in the north-east corner of the project area immediately east of the YB7 magnetite target (see Fig 1).

The chargeability anomaly on the northeast portion of the grid correlates with copper-gold workings, tourmaline breccias, and a deep, weak to moderate magnetic anomaly. Consequently, the anomaly may be indicative of IOCG-style mineralization.

The shallow portion of the chargeability anomaly in the quebrada will be mapped and sampled in detail to determine the possible chargeable source. Following mapping, the chargeability anomaly east of the quebrada will be drilled.

Figure 2- Yerbas Buenas Interpretation Summary Showing Magnetic, Chargeability, and Resistivity Features.

Figure 2 above displays shallow strongly-magnetic targets (magnetite) in dark red and deeper moderatelymagnetic targets are shaded in beige.

The main shallow and deep chargeability anomalies are shaded in mauve and light blue. A resistive body that correlates closely with the YB3-YB8 body is shaded in pale green.

Interpreted structures are shown in black. The NNW-trending interpreted structure is based on a strong resistivity break on each of the IP lines. The WNW interpreted structure is based on distortion in the resistivity and chargeability anomalies on the southern 3 lines.

The 200m, 300m and 400m plan images all show the emergence of another IP structure on the southern most IP line and this is currently being surveyed with additional lines.

The chargeability inversion plots shown in plan and presented in Figure 3 all clearly show a structure that widens out to the east and extends to the north as it deepens. It is open to both the north and east.

Detailed cross sections for each IP line are provided in Figure 6. Line 6724100N shows the emergence of what appears to be another potential sulphide structure. Three additional IP lines have now been run and data is being interpreted.

Management Commentary

Freehill’s Chief Executive Officer Peter Hinner commented: “The completion of the IP survey is a significant step forward in verifying the presence of what we believe is a large sulphide structure that may host the copper and gold mineralisation typically found at surface in the area. A drilling program is already being planned for the second quarter that will target the anomaly.

“Yerbas Buenas is shaping up as a significant Chilean magnetite project with established offtake agreements and third party processing operations available to us only 30 kilometres from site. We look forward to updating shareholders with results from the recent drill campaign and geophysics survey. Discovering this large IP anomaly so close to other copper and gold mineralisation is a great development and substantially improves the project’s potential for gold and copper mineralisation.”
