Competent Person’s Statement The information in this market announcement that relates to exploration results is based on information compiled by Mr Jason Beckton, who is a Member of the Australian Institute of Geoscientists. The information in this market announcement is an accurate representation of the available data for Montezuma project. Mr Beckton, who is Executive Director – Resource Development at Lode, has sufficient experience which is relevant to the style of mineralisation and type of deposit under consideration and to the activity which he is undertaking to qualify as a Competent Person as defined in the 2012 edition of the ‘Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves’. Mr Beckton has a beneficial interest as a shareholder and option holder of Lode and consents to the inclusion in this announcement of the matters based on the information in the form and context in which it appears. Equivalent Grades Used for Montezuma Antimony and Silver Project 1&2 1 LDR is reporting both antimony and silver equivalent grade figures due to interchanging dominance of these two metals from intercept to intercept. Metal equivalent grade figures are a method of demonstrating overall metal endowment for all significant metals’ grades in a single grade figure for each intercept and thus allowing a simpler comparison between intercepts. Montezuma’s reported antimony and silver equivalent figures are based on conversion factors as follows: SbEq(%) = Sb(%) + 0.00281*Ag(g/t) + 0.056*Pb(%) + 0.29*Cu(%) and AgEq(g/t) = Ag(g/t) + 355*Sb(%) + 20*Pb(%) + 101*Cu(%). Metal equivalent conversion factors were calculated using 30 December 2024 metal prices of US$34,747/t antimony, US$29.1/oz silver, US$1,912/t lead and US$8,705/t copper. The antimony price was calculated as an average of several antimony products in a number of markets. Metal equivalent conversion factors were calculated using a preliminary flotation test carried out by ALS Metallurgy (Burnie) in September 2019, where recoveries achieved were 74.5% antimony, 77.9% silver, 75.8% lead and 84.8% copper. It is Lode’s opinion that all the elements included in the metal equivalents calculation have a reasonable potential to be recovered and sold. 2 Tin and Gold assay figures are not included in equivalent figures as gold was not assayed in an early flotation test.
